Bit Explanation:

Master_Motor_Enable: When the Master sets (1) this bit the motor movements are allowed (from digital inputs and from fieldbus) unless an emergency occurs. If the Master resets (0) this bit no motor movement will be allowed and the bit Motor_Movement_Not_Executed in the Drive_Register object will be set if a motor movement command is received via fieldbus or via digital inputs. Also the power to the motor is no supplied any more (the feedback feature is disabled as well). When the Master sets this bit again it is necessary to waits 3-4 seconds before issuing new movement commands. It is recommended to perform an homing procedure since the motor position (Position_Actual_Value object) is not valid any more.

Master_Motor_Fast_Stop: When the Master sets (1) this bit the motor will perform a immediate stop (without ramp) if the motor is running.

Master_Alarm_Reset: When the Master sets (1) this bit the Error_Register object, and the bits #4, 5, 6, 7, 8, 14 of Drive_Register object are cleared.

Reset_Feedback_Displacement: When the Master sets (1) this bit the Feedback Displacement is reset. See Closed Loop Modality for details.

Feedback_Calibration_Strong: When the Master sets (1) this bit the Feedback Calibration Strong is forced. See Closed Loop Modality for details.

Master_Watchdog: The master have to toggle (0/1) this bit each time it writes the Master_Register object. If drive don’t receive a write access to this object within the Master_Watchdog_Timeout the bit Master_Watchdog_Timouted of Drive_Register object is set.

Notes:

The checking for the Master_Watchdog bit starts the first time the master perform a write access to this object. The Master_Motor_Enable bit is set (1) by default to enable motor movement when the drive acts as standalone or when the master do not want to handle the Master_Register object. The default value of bit #0 depends on the value of the bit #5 of Drive_Working_Settings_Extended.
