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 model)
The alarm output (ALM) terminals in each SERVOPACK individually operate differ-
ent alarm detection relays: 1Ry, 2Ry, and 3Ry respectively.
When the alarm occurs, the ALM output signal transistor is turned OFF.
