The maximum torque of the drive is limited by the following:
– Dimensioning
If BOSCH ASC is dimensioned too small the necessary torque is
automatically limited due to a motor current which is too low.
– Programming the Motor Parameters CP.25 - CP.30
Dependent on the adjusted motor data a speed-dependent limit
curve (see below) is set. The value of the calculated maximum
torque is automatically written in parameter CP.9
Parameter CP.31 (Load motor dependent parameter) activates
the motor data and the respective limit curve.
See table on page GB48 for the factory setting of the motor
parameter!
