Wiring
• Provide the specified clearances between the SERVOPACK and the control panel or with
other devices.
Failure to observe this caution may result in fire or malfunction.
• Do not apply any strong impact.
Failure to observe this caution may result in malfunction.
• Connect the ground terminal
to electrical codes (ground resistance: 100
Ω
or less).
Improper grounding may result in electric shock or fire.
• Use the thermal protector built into the servomotor according to either of the two following methods.
SGMVH servomotors are cooled by a fan. If the fan is defective or power to the fan is disconnected, heat from the
motor may result in burns or fire.
Method 1:
• Wire the output from the thermal protector to the host controller and turn OFF the servo when the thermal
protector operates.
Method 2:
• Wire the thermal protector to the operating circuit of the main circuit magnetic contactors or the host
controller and turn OFF the main circuit magnetic contactor when the thermal protector operates.
