Force/torque mode
7.2.1
Function: Current regulation
In the force/torque mode, the motor controller receives the force/torque setpoint value (current set-
point value) via the control interface (fieldbus/analogue input/Festo Configuration Tool (FCT)). The
current regulator processes the deviation between the “current setpoint value” and the “actual current
value” and thus controls the output stage and the connected motor.
All specifications on forces/torques refer to the motor nominal torque or the motor nom-
inal current. Since force/torque are proportional to the motor current, only the current
regulator is activated in this operating case.
