246 Parameters
26.41 Torque step When enabled by parameter 26.42 Torque step enable, adds
an additional step to the torque reference.
A second torque step can be added using pointer parameters
26.43 Torque step pointer enable and 26.44 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 25.11 Speed control min torque and
25.12 Speed control max torque, a ramp stop may be
impossible. Make sure the torque step is reduced or disabled
when a ramp stop is required.
