    You must ensure that the new encoder contains the correct motor data. If it does not, the motor may perform uncontrolled motions, leading to considerable material damage. You can purchase a preprogrammed encoder module from the Siemens Service Center by quoting the relevant order number and serial number. If your encoder module is not preprogrammed, it must be programmed with the correct motor data prior to use.
