16AC Servomotors/Servo Drives 1S-series Instruction Manual
Keeping Foreign Objects Out of Units
• Take measures during installation and operation to keep foreign objects such as metal parti-
cles, oil, machining oil, dust, or water out of the Servo Drive.
• Place a cover over the Servo Drive or take other preventive measures to keep foreign objects
such as drill filings out of the Servo Drive during installation. Be sure to remove the cover after
installation is complete. If the cover is left on during operation, heat dissipation from the Servo
Drive is blocked, which may result in malfunction.
Wiring Diagram
• The above diagram shows the wiring of Servomotor on the temperature protection.
• The length of integrated cable must be 50m or less.
*1
• Connect a leakage breaker and fuse as a protection element.
*1 The cable length does not meet the EMC Directives.
Refer to Compatibility Conditions of EU Directives.
Overload Characteristics (Electronic Thermal Function)
• Solid state motor overload protection is provided in each model.
• The overload protection (electronic thermal) function is built into the Servo Drive to protect the
Servo Drive and Servomotor from overloading. If an overload occurs, first eliminate the cause
of the error and then wait for the Servomotor temperature to drop before you turn ON the pow-
er again. If the error reset is repeated at short intervals, the motor windings may burn out.
• The Servo Drive parameter shall be set at no more than the full load current rating of the Ser-
vomotor.
