Please make sure the mechanical axis is within the range of motion and travelled distance
should not be too long to avoid collision.
Set optimal velocity and acceleration for trial run (not too high!)
Do not modify any gain related parameters during motion to avoid vibration.
Please refer to “Section 3.5 AF_Vog Trial Run” for detailed explanations on how to
perform trial run using front panel operation
4.1.4 Motor rotational direction settings
Motor rotational direction can be changed through Pr0.06 without changing the polarity of
the input command.

Polarity of the command is not inversed. The direction of rotation is
consistent with the polarity of command.
1
Polarity of command is inversed. The direction of rotation is opposite to the
polarity of command.
Note: Rotational direction of the motor is recommended to be set through object dictionary 607E.
However, Pr0.06 has higher priority than object dictionary 607E. 607E only takes effect when
Pr0.06 = 0.
4.1.5 Holding Brake Settings
Holding brake is designed to hold the axis in position to prevent it from sliding due to
applied external forces when the driver is disabled. Holding brake is optional and depends
on the model of motor chosen for the application.
Please only use holding brake when motor is stopped. No applicable when motor is in
motion.
Holding brake coil has no polarity.
Motor should be disabled after stopped.
There is some noise when motors with brake are in motion but that doesn’t affect its
functionality.
Magnetic sensors might be affected when the holding brake is on. Please be aware.
