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 option SIF-485)
1 to 1 control: A PC or PLC controls one inverter (C49 communication address to 001 - 254).
1 to multiple inverters control: A PC or PLC controls several inverters (up to 254) inverters use
parameter C49 to set the communication address (001 - 254). When the communication address
=000, the inverter is controlled by serial communication regardless of the C49 setting.
2.) RS-232communication: (requires RS232 option SIF-232)
1 to 1 control: A PC or PLC controls one inverter (C49 communication address to 001 - 254).
NOTES: a .The BAUD RATE (C50) and communication format (C51/C52/C53) of the Host Computer
or PLC and inverter must be the same.
b. The inverter will validate the modified parameters after the parameters are modified by
the Host Computer or PLC.
c. Communication protocol: refer to the EV MODBUS communication protocol manual
d. Parameters C49 - C53 cannot be changed via the 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, disables the time out function.
Default: 00.0sec *Cannot be modified when in serial communication mode.
2.) Time out operation selection:
000: Deceleration to stop (F02: Deceleration time 1).
001: Free run (coast) to stop.
002: Deceleration to stop (C12: Deceleration time 2).
003: Continue operating.
Default=000 *Cannot be modified when in serial communication mode.
