Description
When enabled by parameter
adds an additional step to the torque reference.
A second torque step can be added using pointer
parameters 26.43 Torque step pointer enable
Torque step source.
The two torque steps work independently of each other,
and are summed up to calculate the total torque step.
Note: For safety reasons, the torque steps are not
applied when an emergency stop is active.
WARNING!
If the total torque step exceeds the limits set
by parameters
and 25.12 Speed control max
stop may be impossible. Make sure the torque
step is reduced or disabled when a ramp stop
is required.
