Assigning I/O devices

External I/O signals for the servo amplifier can be assigned to I/O devices. Also, some signals can be assigned to the I/O
devices without wiring (Automatic ON). 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. Configure settings in
accordance with the system configuration.
Restrictions [G] [WG]
• "Automatic ON" can be set to some input devices, but not to other input devices. For the input devices to which "Automatic
ON" can be set, refer to [Pr. PD01 Input signal automatic ON selection 1].
Restrictions [A]
• "Automatic ON" can be set to some input devices, but not to other input devices. For the input devices to which "Automatic
ON" can be set, refer to [Pr. PD01 Input signal automatic ON selection 1], [Pr. PD41 Input signal automatic ON selection 3],
and [Pr. PD42 Input signal automatic ON selection 4].
• Particular devices such as ABS transfer mode (ABSM) or ABS request (ABSR), and particular connector pin numbers such
as CN3-22 may be changed in functions other than the device setting. In addition, each control mode has restrictions on its
usable devices.
Precautions
• If signals for machine protection such as the LSP (forward rotation stroke end) and LSN (reverse rotation stroke end) are
set to "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.
