n151 RS-422A/485 communications
timeover detection selection
(The time between receiving
PLC signals is monitored, Tim-
eout time: 2 s.)
0: Detects time-over, fatal error, and the Inverter
coasts to a stop.
1: Detects time-over, detects fatal error, and the
Inverter decelerates to a stop in deceleration time
1.
2: Detects time-over, detects fatal error, and the
Inverter decelerates to a stop in deceleration time
2.
3: Detects time-over, detects nonfatal error warn-
ing, and the Inverter continues operating.
4: No time-over is detected.
