13.8.1 Servo ON/OFF
All axis servo ON: Y1
This function executes servo ON/OFF of the servo amplifiers connected to the Simple
Motion module.
By establishing the servo ON status with the servo ON command, servo motor
operation is enabled.
The following two signals can be used to execute servo ON/OFF.
All axis servo ON [Y1]
[Cd.100] Servo OFF command (Buffer memory addresses:
1551+100n[QD77MS2/QD77MS4]/4351+100n[QD77MS16])
A list of the "All axis servo ON [Y1]" and "[Cd.100] Servo OFF command" is given

When the delay time of "Electromagnetic brake sequence output (PC02)" is used,
execute the servo ON to OFF by "[Cd.100] Servo OFF command". (When all axis
servo ON [Y1] is turned ON to OFF, set "1" in "[Cd.100] Servo OFF command" and
execute the servo OFF. Then, turn off [Y1] after delay time passes.)
Refer to each servo amplifier instruction manual for details of servo ON command
