Alarm occurrence timing chart
In the torque mode, the forced stop deceleration function is not available.
To deactivate the alarm, cycle the control circuit power, give the error reset command from the controller, or perform network
communication reset. However, the alarm cannot be deactivated unless its cause is removed.
When you use the forced stop deceleration function
• To enable the function, set "2 _ _ _ (initial value)" in [Pr. PA04].
• Disable the forced stop deceleration function for a machine in which multiple axes are connected together,
such as a tandem structure. If an alarm occurs with the forced stop deceleration function disabled, the servo
motor will stop with the dynamic brake.
When the forced stop deceleration function is enabled
*1 The model speed command is a speed command generated in the servo amplifier for forced stop deceleration of the servo motor.
CAUTION
• When an alarm has occurred, remove its cause, make sure that the operation signal is not being input, ensure safety, and reset the alarm before restarting
operation.
