CSTCA: Torque control with commutation angle

CSTCA is the abbreviation for "Cyclic synchronous torque with commutation angle".

This operation mode is a current control similar to CST. In addition the user can specify the commutation angle.

You cannot use TwinCAT NC to specify speed and commutation angle. The variable “Commutation angle” can be used to set an angle that is to be maintained with a defined set current of the variable “Target torque”. By specifying a leading angle, a movement can be achieved in this operation mode.
