C51 Stop bit
000: 1 Stop bit
001: 2 Stop bit
C52 Parity bit
000: No parity
001: Even parity
002: Odd parity
C53 Data bits
000: 8 bits data
001: 7 bits data
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 (up to 254
inverters with C49 set as 001~254). 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 error detection time / Communication error operation selection
(1) Time –out detection time: 00.0~25.5sec; setting 00.0 sec: disable time-out function.
Default: 00.0sec
*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
*Cannot be modified during communication.
