The complete torque motors can be operated in 4 quadrants. They can be connected to a
controlled or uncontrolled infeed unit.
Uncontrolled motor motion as a result of incorrect adjustment
The encoders are adjusted in the factory for SIEMENS drive converters. Another encoder
adjustment may be required when operating the motor with a third-party converter.
Incorrect adjustment of the encoder regarding motor EMF can lead to uncontrolled motion
which can cause injury and material damage.
• Only replace an encoder and adjust it if you are appropriately qualified to do so.
• When a belt-driven encoder is replaced, adjust the position of the encoder system with
respect to the motor EMF.
• You must re-reference the system when replacing an absolute encoder.
Note
Replacing a coaxially mounted encoder
When replacing a coaxially mounted encoder, you do not have to adjust the encoder system.
The
position with respect to the motor EMF is ensured using mechanical components.
