Operation
4-6-2 Parameter Details
Setting Explanation
• This parameter sets the Servomotor’s direction of rotation.
Setting Explanation
• Select the stopping method for when the servo is turned OFF or an alarm occurs.
Note 1. If function switch 6 is OFF to enable the function switch settings, this parameter is ignored
and the setting on function switch 2 (dynamic brake setting) is used.
Note 2. If the parameter is set to 0 or 1 and the Servomotor is turned by an external force to 20 r/min
or faster after the dynamic brake has stopped the Servomotor, the Servo ON status will not
be entered even if the RUN signal turns ON.
Note 3. The dynamic brake will operate when the main circuit power supply or the control power sup-
ply is OFF regardless of the setting of this parameter.
