3.3.5 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)
The following example shows the Σ-V series SGDV SERVOPACK (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.
Note: For M-II model, M-III model, and command option attachable type SERVOPACKs, the
pin number of ALM+ terminal is CN1-3, and that of ALM − terminal is CN1-4.
