Closed Loop Current Limit
633 Startup Torque, Forward
Sets the startup torque for forward direction, if selected with par. 1.6.17.12.
634 Startup Torque, Reverse
Sets the startup torque for reverse direction, if selected with par. 1.6.17.13.
107 Current Limit
This parameter determines the maximum motor current from the frequency converter. The parameter value range
differs from size to size. On closed loop control mode, this limits torque (= torque producing current).
For example, if motor magnetizing current is 2.0A and current limit is 1.0A, total motor current can be:
l
d
2
+ l
q
2
I =
