For 0 pulses/s, set the torque to be used during stall
prevention operation.
For 400k pulses/s, set the torque command to be used
during stall prevention operation.
Set the torque current limit level.
The torque limit setting value is used for limiting the torque
current level.

Constant torque
command
The torque is constant
unless the output limit of
the torque current is
reached. (The torque
current is limited.)
