Torque Mode
In the torque mode the drive does only control the current in the motor. This control loop is
very fast but the speed is moving with the load due to the constant current. This mode is
used in application with force control or as a fast power amplifier for position systems.
Encoder Mode
At encoder mode feedback information is coming from the encoder signals. The encoder is
mounted at the motor. The speed regulation has got a high performance at each load
condition and qualified for each application to control exactly the speed of a system
especially for low speed application. The maximum achievable speed in this mode is limited
through the encoder input frequency.
Analog Position Mode
The analog position mode is using a voltage feedback generated by a potentiometer which
is mounted e.g. on the motor axis. This mode can be used to control the movement or the
position of a flap, a wheel or a linear actuator. The range of the movement depends of
working range of the feedback system.
