5.1.10 Communication error measures
When executing run commands or applying command data via RS-485, it is possible to continue
running the inverter without tripping the alarm, even if there is a transmission error, by
implementing the following measures. The following examples show communication alarms
(keypad displays er5 ) generated when operating the inverter from the master side.
(a) H32 = 0; Forced stop (Forced stop: idling stop during alarm)
(b) H32 = 1; Idling stop after set time elapses following transmission error
(Operation stops after continuing for timer set time, H33: timer time = 5.00 s)
(c) H32 = 2; Operation continues if cause of transmission error is resolved within timer time set in
(b) above.
(Operation stops after error continues beyond timer set time, H33: timer time = 5.00 s)
(d) H32 = 3; Operation continues even after transmission error occurs (continued operation).
