8.7. ADJUSTING THE UP-DOWN MOTOR CURRENT LIMITER
Figure 8.7-1
1. Carry out the procedures described in
paragraph 7.16. “Disassembling the
electronic circuit boards”.
The operations described below must be
carried out with the machine powered
up; they should be performed
exclusively by a QUALIFIED
TECHNICIAN who must ensure that
there are no unauthorized persons near
the machine.
2. To adjust the current limiter setting, turn the
screw of trimmer R68 on the driver board
using a small flat-blade screwdriver, until the
optimal level is attained.
WARNING: do not move this trimmer
unless absolutely necessary. In any case,
always check the reason why the current
increase is necessary (increased friction,
mechanical parts obstructing the
movement, electrical problems with the
motor) before adjusting the trimmer.
WARNING: after adjusting the trimmer
to increase the motor current, always
check that its value does not exceed 5 A,
which is the maximum current
permitted by the motor.
