applies in either direction when the machine is producing regenerating torque. The symmetrical current limit can override either motoring or
regenerating current limit if it is set at a lower value than either limit.
and so Pr 4.08 should be used for fast updating if required.
When this parameter is set to 1, 2 or 3 the ramps are not active while the drive is in the run state. When the drive is taken out of the run state, but not
disabled, the appropriate stopping mode is used. It is recommended that coast stopping or stopping without ramps are used. However, if ramp stop
mode is used the ramp output is pre-loaded with the actual speed at the changeover point to avoid unwanted jumps in the speed reference.
0: Speed control mode
The torque demand is equal to the speed loop output.
1: Torque control
The torque demand is given by the sum of the torque reference and the torque offset, if enabled. The speed is not limited in any way, however, the
drive will trip at the overspeed threshold if runaway occurs. When ‘RUN FWD / RUN REV’ is removed while in ‘Torque mode’, the drive will stop
in the method selected by Pr 6.01 .
