3 BASIC FUNCTION
3.16 Electromagnetic brake interlock function
■
Alarm occurrence
When an alarm occurs, the servo motor stops using the same method as with the dynamic brake.
Page 127 Stopping with dynamic brake
■
When both the main circuit power supply and the control circuit power supply are turned off
The same timing chart shown in "When both the main circuit power supply and the control circuit power supply are turned off"
applies here when using the forced stop deceleration function.
Page 138 When both the main circuit power supply and the control circuit power supply are turned off
■
When the main circuit power supply is turned off and the control circuit power supply is on
When a voltage drop is detected, 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

Ready-off command from controller [G] [WG]
The same timing chart shown in "Ready-off command from controller" when using the forced stop deceleration function,
applies here.
