4.11.4 14-3* Current Limit Control
The frequency converter features an integral current limit
controller which is activated when the motor current, and
thus the torque, is higher than the torque limits set in
parameter 4-16 Torque Limit Motor Mode
and
parameter 4-17 Torque Limit Generator Mode
.
When the current limit is reached during motor operation
or regenerative operation, the frequency converter tries to
reduce torque below the preset torque limits as quickly as
possible without losing control of the motor.
While the current control is active, the frequency converter
can only be stopped by setting a digital input to
[2] Coast
inverse
or
[3]Coast and reset inv.
