AUTO-BRAKE MOTOR
19.2 SP1
SEZ_GB19
19-1 AUTO-BRAKE MOTOR
At least every 2 months or 500 stops, check and adjust the electromechanic braking device illustrated in fig.19.1.
Before carrying out any intervention on the motor, shut off the power by turning the padlockable main switch
to 0.
Electromagnet brake clearance
Distance between electromagnet and mobile core is called “air gap” and is adjusted during device construction.
Adjustment is required only in case of replacement of mobile core having glued to its surface a brake disk of
friction material being subject to wear .
Wear limit of friction disk is 3 mm.
Replacement is to be carried out only by technicians of SCM dealer.
Adjustment of braking unit
Braking efficacy reduction can be noticed by the increase of the time required to fully stop the cutterblock/spindle
(max. time 10 seconds) in case of tool of max. size and at the maximal permitted speed.
To reset the best braking torque proceed as follows:
- insert an 5-6 mm Allen wrench into the hole on cover for the fan in order ot reach the adjusting screw.
- progressively screw down screw in order to join the mobile elements and to eliminate distance (brake
clearance).
- unscrew screw by min. 1/4 turn (max. 1/3 turn) (corresponding to about 0.4mm air gap)
- start and stop the motor a few times to check the correct running.
