5.6 Other Output Signals
5.6.1 Servo Ready Output Signal
The servo ready output signal (/S-RDY) is a indicate signal that the servo unit can receive servo
ON (/S-ON) signals and command signals.
This signal is output under the following conditions:
The main circuit power is on. For details on the output timing of /S-RDY during power-on,
see “Power-up enable ON timing”.
Non-hardwired base blocking status.
No alarm occurred.
When using an absolute encoder, the SEN signal turns ON (H level).
1)
Parameter configuration of servo-ready
In the factory default digital output configuration, the signal is configured as CN1 25, 26 pin
(Pn613=0x00) by default. Please confirm before use.
2)
Wiring of servo ready
The servo ready signal is a general configurable Digital output. See “Sequence Output Circuit” for
wiring details.
5.6.2 Warning Output Signal
The warning output signal (/WARN) is a warning function before the alarm, which makes it easier
for the host device to judge the operation of the servo unit in advance. For detailed warning code,
please refer to “Warning Code”.
