F532

Drive motor parameters setup incomplete.

Before a motor can be enabled, you must configure a minimum set of parameters. These parameters have not been configured.

Issue the command DRV.SETUPREQLIST to display the list of the parameters that you must configure. Configure these parameters either manually or automatically. You can manually configure these parameters in three ways: (1) set each parameter individually; (2) use the setup wizard to select the motor; or (3) select the motor type from the motor data base in the Motor window (MOTOR.AUTOSET must be set to 0 (off)). If you use the Motor window, you must first select the feedback type. If the motor has Biss Analog, Endat, or SFD feedback (feedback with memory), then these parameters are set automatically when MOTOR.AUTOSET is set to 1 (on).

F534

Failed to read motor parameters from feedback device.

Motor either does not have motor feedback memory, or the motor feedback memory is not programmed properly so the parameters cannot be read.

Try to read parameters again by clicking the Disable and Clear Faults button, or by issuing the DRV.CLRFAULTS command. If this attempt is not successful, then set MOTOR.AUTOSET to 0 (off) and program the parameters using the setup wizard or manually set up the parameters. If the motor has motor memory (Biss Analog, Endat, and SFD motors have motor memory), return the motor to have the memory programmed.
