• When the magnetic contactor drive output is disabled
When an alarm occurs, turn off the magnetic contactor using an external sequence and shut off the main circuit power supply.

Position command
*1 If an electromagnetic brake is installed externally, configure the circuit so that the electromagnetic brake operates with MBR as
described below.
ON: Electromagnetic brake is not activated
OFF: Electromagnetic brake is activated
*2 Give a position command after the externally-installed electromagnetic brake is released.
*3 When in the position control mode.
*4 In the drive unit parameters, set the delay time (Tb) from when the MBR shuts off at servo-off until base circuit shut-off.
*5 This is the case when in the ready-on status during servo-off. In the ready-off status, the base circuit is turned off at the same time as the
servo-on command is turned off. (Tb = 0)
