Zero speed time at start
After giving the start command the drive will remain at zero speed for the time
defined by this parameter. The ramp is released to follow the set frequency/speed
reference after this time has elapsed.
616
Zero speed time at stop
The drive will remain at zero speed with controllers active for the time defined by this
parameter after reaching the zero speed when a stop command is given. This
parameter has no effect, if the selected stop function (P1.4.7) is coasting.
621
Start-up torque
This parameter selects the start-up torque.
Torque Memory is used in crane applications. Start-up Torque FWD/REV can be used
in other applications to help the speed controller.
0 = Not Used
1 = TorqMemory
2 = Torque Ref
3 = Torq.Fwd/Rev
633
Start-up torque, forward
Sets the start-up torque for forward direction, if selected with par. 1.6.17.12.
634
Start-up torque, reverse
Sets the start-up 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 2.0 A and current limit is 1.0 A, total
motor current can be:
