3 BASIC FUNCTION
3.16 Electromagnetic brake interlock function
■
When both the main circuit power supply and the control circuit power supply are turned off
When the base circuit is turned off, the servo motor is stopped with the dynamic brake and electromagnetic brake.
*1 The length of time varies depending on the operation status.
*2 ON: Electromagnetic brake is not activated
OFF: Electromagnetic brake is activated
■
When the main circuit power supply is turned off and the control circuit power supply is on
In the torque mode and continuous operation to torque control mode, the forced stop deceleration function
cannot be used.
Forced stop deceleration starts when a voltage drop is detected, and after the base circuit is turned off the servo motor is
stopped with the dynamic brake and the electromagnetic brake.
*1 ON: Electromagnetic brake is not activated
OFF: Electromagnetic brake is activated
*2 The length of time varies depending on the operation status.
