1. RS-485 communication: (requires RS485 port device)
1 to 1 control: PC or PLC or controller controls one inverter (C49 is set to 001~254).
1 to multiple drives control: PC or PLC or other controllers control several inverters (The
maximum of inverter could be controlled is 32). When the communication address =000, the
inverter is controlled by communication regardless of the C49 setting.
2. RS-232communication: (requires RS232 port)
1 to 1 control: PC or PLC or controller controls one inverter (C49 is set to 001~254).
Note: a
. The BAUD RATE(C50) and communication format (C51/C52/C53) of PC (or PLC or
other controller) and inverter should be the same.
b
. The inverter will validate the modified parameters after the parameters modified by PC.
c
. Communication protocol: refer to EV communication protocol description.
d
. Parameter C49~C53 can’t be changed via communication module
C54/ C55
Communication time-out detection time / Communication time-out operation
selection
(1)
Time-out detection time: 00.0~25.5sec; setting 00.0 sec: disable time-out function.
Default: 00.0sec
Communication time-out detection enable or not is according to C54
，
not relationship with
Run/Frequency command.
*Cannot be modified during communication.
(2)
Time-out operation selection:
000: Deceleration to stop (F02: Deceleration time 1).
001: Free run to stop.
002: Deceleration to stop (C12: Deceleration time 2).
003: Continue operating.
Default=000
Reset method:
a. Push the “Reset” button directly.
b. Receive correct Modbus data from Master.
After communication time-out, the motor decelerates to stop (C55 = 000, 001, 002). And the
motor does not run automatic after reset, the inverter must set the run command again to
restart.
*Cannot be modified during communication.
*Detail list please see Appendix.
