• If the operation mode is changed to Homing mode during the motor operation, the motor performs 
the stop operation according to the setting of Halt option code (605D hex).
• If a motion command of Homing mode or Profile position mode is input during a deceleration stop 
operation, the motor starts the Homing operation or Profile position operation.
If you change the operation mode to another mode while the motor is performing the homing operation, 
a command error will occur.
You can check the actual operation mode from the Modes of operation display (6061 hex).
Some of the bits in the Statusword (6041 hex) are dependent on the operation mode. Their relation-
ship with Modes of operation display (6061 hex) is shown in the following table:
