3.1 Precautions on Wiring
E-19
English
„ Other Precautions
• Make sure that the emergency-stop circuit turns OFF the /S-ON signal as well as the power supply of the main
circuit. Refer to 3.14 EMG Sequence.
• An overtravel function is not provided for the SERVOPACK.
For system safety, include a sequence so that the /S-ON signal will turn OFF when the limit switch is activated.
• If the servomotor is used to drive a vertical axis, install a safety device with an alarm function to prevent the
workpiece from falling down. Failure to observe this precaution may result in injury or damage to the equipment
from fallen workpieces.
• Install an interlock system in the circuit to avoid any accident when opening or closing the machine’s protective
cover.
• Whether the electricity is served or not to the motor, do not use the motor being rotated from the outside.
• When restarting the power supply soon after turning OFF, alarm may occur to the SERVOPACK. Refer to the
power supply holding time in the following table to restart the power supply correctly.
