4.3 Wiring the Power Supply to the SERVOPACK
4.3.3 Power Supply Wiring Diagrams
4-10
Using More Than One SERVOPACK
The following diagram shows the wiring to stop all of the Servomotors when there is an alarm
for any one SERVOPACK.
More than one SERVOPACK can share a single Noise Filter. However, always select a Noise Fil-
ter that has a large enough capacity to handle the total power supply capacity of all the
SERVOPACKs. Be sure to consider the load conditions.
Note: When you shut OFF the power supply with a magnetic contactor or other device, do so before the insulated
AC/DC converter for the power supply.
