Assigning I/O devices
Signals can be assigned to the external I/O signal of the servo amplifier. Also, the signals can be set to be automatically
turned on without wiring. In addition, if the external input signal causes chattering due to noise or other factors, the input filter
can be used to suppress the effect of noise. The polarity of the DI pin can also be set. Set in accordance with the system
configuration.
Restrictions
• Some input devices can be set for automatic on, and some cannot. For the input devices that can be set for automatic on,
refer to [Pr. PD01 Input signal automatic ON selection 1].
Precautions
• If signals for machine protection such as the LSP (forward rotation stroke end) and LSN (reverse rotation stroke end) are
set for automatic on, protection by the servo amplifier is disabled. Therefore, ensure the safety for the entire system.
• If the polarity of the DI pin is set to "ON with 0 V input", the DI pin may turn on when the input circuit malfunctions. For this
reason, it is not recommended to set the polarity of DI pins to which signals related to machine protection such as LSP
(forward rotation stroke end) or LSN (reverse rotation stroke end) are assigned to "ON with 0 V input". If doing this setting,
ensure the safety in the entire system.
