Precautions When Using More Than One SERVOPACK
This section shows an example of the wiring when more than one SERVOPACK is
used and the precautions.
• Wiring Example (Analog pulse model)
Connect the alarm output (ALM) terminals for the three SERVOPACKs in series to
enable alarm detection relay 1RY to operate.
When the alarm occurs, the ALM output signal transistor is turned OFF.
