7-2-1 Turning ON the Servo
7-2 Turning ON the Servo
You can turn the Servo ON or OFF to enable or disable sending operation commands to the Servo
Drive. The MC_Power (Power Servo) motion control instruction is used.
Specify the axis to move with the Axis in-out variable. Change the Enable input variable for MC_Power
to TRUE to turn ON the Servo. Change Enable to FALSE to turn OFF the Servo.
Precautions for Correct UsePrecautions for Correct Use
⢠If you change Enable to FALSE while the axis is moving, the command stops immediately and
all motion control instructions for that axis are disabled.
⢠If you use an NX-series Pulse Output Unit, you must provide a separate means to turn the
power supply to the motor drive ON and OFF. Refer to the NX-series Position Interface Units
Userās Manual (Cat. No. W524) for details.
If an OMRON 1S-series Servomotor or G5-series Servomotor with an absolute encoder is used,
or if an OMRON G5-series Linear Motor Type Servomotor/Servo Drive with built-in EtherCAT
communications is used with an absolute external scale, home is defined when the Enable input
variable to the MC_Power instruction changes to TRUE.
For a CPU Unit with unit version 1.10 or later, if an OMRON 1S-series Servomotor or G5-series
Servomotor with an absolute encoder is used, or if an OMRON G5-series Linear Motor Type
Servomotor/Servo Drive with built-in EtherCAT communications is used with an absolute exter-
nal scale, home is also defined when EtherCAT process data communications change from a
non-established to an established state, in addition to the step shown in the above Additional
Information.
