Function
This parameter defines the type of reference to be used. The torque control may
be set up (see section Torque Control (VTC and FOC Only) as well).
When the Torque control with speed limit mode is used, the drive will limit the
motor rotation to the rpm set in parameter C029 (C072, C115).
This function can be used to automatically toggle from the torque control mode
to the speed control mode: when the torque control mode is implemented, the
motor speed can reach any value included in the “AB” area (see figure below).
If the limit speed is attained due to particular load conditions, the drive will
automatically switch to the speed control (“BC” zone). The controlled torque is
no longer maintained.
If the torque returns to its setpoint value, the drive wi
ll automatically switch to the
torque control again (“AB” zone).
