7.5 Setting Up the SERVOPACK
7-25
As shown in the table above, the P-OT signal can be allocated to any input terminal from CN1-7 to
CN1-13. P-OT is always invalid. When Pn50A.3 is set to 7, and so the SERVOPACK will always be in
forward run prohibited status.
The P-OT signal is not used when Pn50A.3 is set to 8. This setting is used in the following instances.
• When the factory set input signals are to be replaced by another input signal.
• When the forward run prohibited (P-OT) and the reverse run prohibited (N-OT) input signals are not
required in the system configuration for trial or normal operation.
The forward run prohibited (P-OT) and the reverse run prohibited (N-OT) input signals are valid when OFF (high
level). The input terminals must therefore be wired so that these signals remain ON (low level) in systems where
they are not required. The need to wire these terminals can be eliminated by setting the Pn50A.3 to 8.
Signals are input with OR logic when multiple signals are allocated to the same input circuit.
