The plotted 0.4 MPa point is below the specified 0.5 MPa operating minimum and does not extend the permitted operating range. The curve is a theoretical reference, not a measured rating of an individual unit.
Source discrepancy: the specification and theoretical curve both give 5.7 T at 0.6 MPa. The dimension-page force table instead prints 4.7 T for NPM60T70X15. This description uses the matching specification/curve value as the reference and records the conflicting dimension-page value; “60T” remains a nominal 6.0 T class code, not a guaranteed 6.0 T output at 0.6 MPa.

Operating sequence
During release, air enters the upper pneumatic chamber and drives the pneumatic piston downward. The oil pressure increases and pushes out the hydraulic piston rod to release the tool.
During return, air enters the lower pneumatic chamber and raises the pneumatic rod; the hydraulic piston rod returns under spring force.
At the tool-release end position, the two small air passages align and automatically enable spindle blowing. Adjust the blowing flow at the dedicated connector.
Where fitted, an L-shaped plate operates the microswitch at the stroke limit. Its signal belongs in the tool-change control sequence and must be coordinated with the other machine motions.
Installation and commissioning
Install vertically above a vertical spindle on a rigid support. Keep the support mounting face perpendicular to the spindle axis within 0.05 mm per 100 mm; misalignment produces reaction force and reduces service life.
Set the hydraulic release position before operation. With the upper chamber supplied and the tool-release cylinder fully extended, adjust the release bolt so that the tool is released by the required amount. The source examples are BT30: 0.2–0.4 mm, BT40: 0.4–0.7 mm and BT50: 0.5–1.0 mm. Do not use less than the required minimum release amount.
Loosen the locking-coil screw to set clearance A between the fixing screw and drawbar, test release repeatedly, then lock the setting. Excessive projection can bend the drawbar or damage the spindle.
With no release command, the spindle drawbar must not contact the pneumatic-cylinder screw. If contact occurs, reduce the drawbar length or use an appropriate longer-stroke cylinder.
When microswitches are fitted, adjust them separately at both travel ends. Move the switch toward the plate until it operates, then depress a further 0.5–1.5 mm and fix it. Set the PLC delay so release and tool-pulling motions do not cause premature pulling or excessive pulling.
Oil, air supply and maintenance
The installation guidance recommends stable 0.6–0.8 MPa air and a pressure switch to enforce the minimum machine pressure. This recommendation is narrower than the general 0.5–0.8 MPa specification. Excess pressure shortens seal life; insufficient pressure reduces release force.
Use clean air and drain the air-treatment unit regularly. Prefer a dedicated supply; where machines share a supply, size the air receiver to reduce pressure fluctuation.
The oil reservoir recommendation is ISO VG32 anti-wear hydraulic oil. Cycle the cylinder repeatedly after initial filling to purge air, and keep the oil level within its marked range.
Inspect the reservoir periodically and replenish or replace oil. The source suggests an initial replenishment interval of six months or more; if replenishment becomes necessary about monthly, renew the oil. Use the same manufacturer and grade when replenishing; do not mix other oils.
The reservoir float contains a magnet and supports G-profile CMSG / DMSG / EMSG sensing for low liquid level. This is reservoir-level detection, not a claim that the hydraulic piston accepts the same sensor.
Choose sufficient release force for the spindle; the catalog guide uses roughly 3–4 times the spindle clamping force and gives typical classes of 3.5 T for a 40-size spindle, 4.5 T for a 50-size spindle and 6 T for a high-power 50-size spindle. Validate the actual machine requirement.
Secure microswitches, use correctly dimensioned drawbars and tool holders, and avoid over-long or over-short parts that cause sticking or damage. Remove the last tool from the spindle before shutdown rather than leaving it installed as the spindle cools.

The listed G-profile sensors are separately ordered alternatives for the NPM oil-reservoir magnetic float and low liquid-level signal. They do not detect hydraulic-piston position or replace the separate L-option mechanical end-position microswitches. Select a sensor circuit and controller supply independently of the main solenoid-valve voltage. A final -H on a CMS order code selects the high-temperature reed version.
CMSG reed sensors are limited to 100 mA, 10 W and 200 Hz, with no internal consumption or leakage. Standard/A05 voltage drop is at most 2.5 V at 100 mA DC; versions with the final -H suffix have no residual voltage or indicator LED.
Two-wire DMSG and EMSG require 2.5–100 mA loads, up to 2.8 W and 1,000 Hz. Maximum consumption, residual voltage and leakage are 3 mA, 3.5 V and 0.06 mA respectively.
NPN/PNP DMSG outputs are rated to 30 V / 200 mA, 6 W and 1,000 Hz. Maximum consumption, residual voltage and leakage are 5 mA, 0.7 V and 0.01 mA respectively. Check controller input compatibility as well as load ratings.
Sensor and female-cable endings 020/030/050/100 mean 2/3/5/10 m. M08/M12 sensors have M8/M12 male connectors on 0.5 m leads; M08010/M08020/M08030 and M12010/M12020/M12030 give 1/2/3 m leads. Select lead length for the reservoir installation and control cabinet independently of the tool-release stroke.
Match female cables to the male connector size and wire count; direct-lead sensors need none. B pinout: 1 brown (+), 4 blue (−), 3 unused. C pinout: 1 brown (+), 3 blue (−), 4 black output. Check the mating cable and connector ratings separately.
A05 flex-resistant robotics cable and A06 oil-resistant flex cable have a recommended minimum bend radius of 19 mm. Both are two-wire direct-lead types, without M8/M12, NPN/PNP or W options; A05-CMSG also excludes the final high-temperature -H suffix. W means waterproof: DMSG-W has direct leads only; the listed EMSG-W options also include connectors.
Sensor temperature limits are −10 to +70°C, or −10 to +125°C for CMSG versions with the final -H suffix. The NPM unit remains limited to −5 to +60°C, so the common range is −5 to +60°C subject to the other installed components. Ordinary, high-temperature and A05 sensors are IP64; W/A06 are IP68. These ratings do not extend to the reservoir, connectors or whole assembly; a sensor rating does not authorize immersion in hydraulic oil.
CMS has no protection circuit; DMS/EMS have reverse-polarity and surge protection, and EMS also has temperature-overload protection. Reed, two-wire electronic, NPN and PNP circuits are not interchangeable. Complete and insulate wiring before powering it; keep it separate from power/high-voltage wiring. For direct leads, connect brown and blue in series with the load on two-wire types; do not connect the switch alone across the supply. On three-wire types, brown is positive supply, blue is negative and black is output; connect an NPN load to positive and a PNP load to negative.
Fit the selected G-profile sensor at the NPM reservoir sensor location shown for its magnetic float, and verify switching at the required low oil level after installation. Do not infer a hydraulic-cylinder body groove or use this signal as a tool-release end-position confirmation. Loosen the sensor locking screw so it does not project below the sensor base, position the sensor, then tighten. Recommended sensor-screw torque is 0.15–0.20 N·m, never over 0.25 N·m; this is not a reservoir or cylinder mounting torque. Keep cables free of strain, avoid unnecessary bending and impacts, and inspect fixings, wiring and indication.
Keep ordinary sensors dry and do not immerse waterproof types for long periods. Avoid explosive gas, aggressive chemicals, sudden temperature changes, welding interference and magnetic debris. Provide suitable protection for A05 cables exposed to heat, dust, water or oil, and for A06 cables exposed to weld spatter.
Matching valve service parts and tube order examples
These separately ordered service options match the integrated valve and tube families already identified for this NPM configuration. They are replacement choices, not an extra operating-valve set or a required accessory bundle. Confirm the installed revision, sealing face, mounting and electrical entry before service.
4M31010F: 12 V DC; DIN plug entry; PT3/8 supply P and PT1/4 exhaust R/S; NAMUR work faceMatching complete-order reference for service replacement of the integrated 4M310 valve.
CDA092F: 12 V DC; DIN coil; 092 family for 4M300Matching replacement coil for the existing valve, selected instead of replacing the whole valve.
4V210-005-P1, 4V210-005-P3: Alternative DIN terminals: P1 plain AC/DC; P3 DC green indicatorChoose one terminal for the selected CDA092 coil; these are alternatives, not a pair.
US98A060040100MBK: Black polyester-PU tube, 6 mm OD × 4 mm ID, 100 m rollComplete packaging example for the existing tube-1 family; cut to the measured installed length.
US98A100065100MBK: Black polyester-PU tube, 10 mm OD × 6.5 mm ID, 100 m rollComplete packaging example for the existing tube-2 family; cut to the measured installed length.
The matched valve uses PT3/8 at supply P and PT1/4 at exhaust R/S; A/B connect through its NAMUR mating face. Do not treat A/B as threaded tube ports. Retain the original NPM release, return and spindle-blowing arrangement. No replacement NAMUR seal or mounting-kit order code is established here.
The selected 12 V DC valve permits ±10% supply variation and consumes 2.5 W. For DIN entry, select either the plain terminal or the listed DC indicator terminal; connect terminal 1 positive and terminal 2 negative. Reversing polarity can leave the indicator off while the valve still operates. Whole-valve and coil-only replacements are alternatives; neither changes the original microswitch option.
Keep the NPM operating limits of 0.5–0.8 MPa and −5 to +60°C, including the original recommendation for stable 0.6–0.8 MPa machine supply. The valve range is 0.15–0.8 MPa and −20 to +70°C; its wider limits do not widen the NPM rating. Actual machine sequencing, release force and air capacity remain governed by the original installation requirements.
The two black 100 m rolls complete the existing PU family codes as packaging examples, not required installed lengths or additional hydraulic piping. Both are rated to 1 MPa at 23°C and −20 to +70°C, subject to temperature derating; minimum bend radii are 15 mm for 6×4 mm and 25 mm for 10×6.5 mm. Match the existing routing, tube dimensions and fittings, cut to actual length, and apply the lowest component limit.Weight reference
