Setpoint management
The setpoint for the torque and speed control modes can be set via a setpoint management system.
Possible setpoint sources are:
3 analogue inputs:
AIN 0, AIN 1, and AIN 2
3 fixed values:
First value: depending on the controller enabling logic:
Fixed value 1 or
RS232 interface or
CANopen bus interface or
PROFIBUS-DP interface or
Sercos interface
Second and third value: fixed values 2 and 3
Process controller
SYNC input
Additional incremental encoder input [X10]
If no setpoint source is activated, the setpoint is zero.
The setpoint management system has a ramp generator with a preceding adder. Via the corresponding selectors, any of the
above mentioned setpoint sources can be selected and run through the ramp generator. Additional sources can be selected as
setpoints by way of two additional selectors. These, however, cannot be run through the ramp generator. The total setpoint is
the sum of all of the values. The ramp can be parameterised as the acceleration or deceleration time depending on the
direction.

Torque-controlled mode
In the torque-controlled mode, a certain torque is preset and generated in the motor by the servo positioning controller. In this
case, only the current controller is activated, since the torque is proportional to the motor current.
