c) Always Valid
Through the setting of parameters Pn610, Pn611 and Pn612, the configured input signal can
always be valid. For example, when Pn610=0x01 (servo enable), the servo is always in the
enabled ON state after power-on, and the external enable signal (/ S-ON) does not take effect.
3.8.3 Confirming the Input Status
The status of the input signal can be checked by input signal monitoring (Un100). The Un100
segment display and corresponding Pin No.s are as follows:

The upper SEG (LED) lights up when the input signal is OFF.
The lower SEG (LED) lights up when the input signal is ON.
The value (address: 0XE100) read over the communication is hexadecimal, for example, the read
value is 0x1FE. Under the default input configuration, it means that the input of /S-ON (CN1-40) is
ON, that is, servo enable, and the input of other input pins is OFF.
