MICRO GEARLESS XAP1-CE
Permanent magnet synchronous motor for commercial lifts

- check the correct function by operating several succeeding
releases and stops.
- adjust the second micro-switch in the same way.
- connect the micro-contacts and the supply of the brakes.
RATED CURRENT
10 ma to 100 ma at 24 VDc.
the maximum lifetime of the micro-switch is only guaranteed
when switching under resistive load.

BRAKE AND MICRO-SWITCH
TOOLS NEEDED
- male hexagon angular offset spanner (2,5 mm) : DIn 911
(extended version : l=90)
- Kit of feeler gauges : 0,1 mm, 0,3 mm et 0,6 mm
- male hexagon angular offset spanner (8 mm) : DIn 911 (non
extended)
- male hexagon angular offset spanner (4 mm) : DIn 911 (non
extended)
- torque spanner for hexagon screw m10 (8 mm) : 30-60 nm

- Grease
- thread glue loctite 242 or equivalent.
Procedure for encoder
7.1 -
replacement
secure the load before any operation on the motor.
make sure that no torque applies to the rotor!
Encoder dismantling procedure
7.1.1 -
- Disconnect the encoder (17)
- Unscrew the 2 socket hex screws cHc m5 (15) from the base
of the encoder (16).
- Remove the base (16) by unscrewing the 2 socket hex screws
cHc m5 (15) and the 2 socket hex screws cHc m3 (14) from
the flexible coupling of the encoder.

TO REMOvE THE ENCODER
- Unscrew the plastic screw on the top of the encoder.
- Unscrew the socket hex crew cHc m5 inside the encoder with
a male angular hexagon offset spanner (4 mm).
- Fit the m6 screw instead of the m5 screw which has just been
removed.
- Remove the encoder and the screw m6 inside of it.
- Unscrew the 2 socket hex crews CHc M3 (14) from the flexible
coupling of the encoder, in order to remove the encoder base
plate.
Reassembly of the encoder
7.1.2 -
- assemble the encoder base plate to the encoder with the 2
socket hex screws (14) on the flexible coupling.
- Place the m5 screw inside the encoder (without putting the
encoder in place).
- Put a drop of loctite on the thread of the m5 screw.
- screw the encoder onto the rotor.
- screw the plastic screw on the top of the encoder.
- Fix the encoder base plate, at the back of the 2 brakes, with
the 2 socket hex screws m5 (15).
Adjusting the encoder (see § 6.2)

disc.
secure the load before any operation on the motor.
make sure that no torque applies to the rotor!
- Disconnect the brake
Fitting the new brake
7.2.3 -
CAUTION !
Do not touch or put any grease or oil on the brake lining!
Use gloves or wash hands if necessary.
- Put a little grease on the rotor splines
- Put the brake disc with its o-rings on the splines, the shoulder
showing forward.
- Push the brake disc to the friction face of the non-drive
endschield of the motor.
- Mount the first brake coil unit.
- Place the 3 spacers on the 3 fixing screws of the brake coil
unit.
- Position the brake coil unit in the right position in relation to
the non-drive endshield of the motor.
- Turn the 3 fixing screws until contact.
- Tighten the 3 fixing screws with torque 44Nm ±10% in the
following order: screw on the top (1), screw on the bottom (2)
and screw in the middle (3), see fig.3.
Note
: Secure the fixing screws (safety washer or thermoplastic
liquid such as loctite)
- Remove the transport screw, see fig.3.
- Proceed to all electrical connections.
- carry out a few successive draws and releases.
- check the airgap (see §6.1).
