IMO iDrive EDX 100V series 1-ph/0.2 – 0.75kW (0.25 – 1HP) Owner's Manual page 65

1. RS-485 communication: (requires RS485 option card)(Option)
1 to 1 control : PC, PLC or other device can control one iDrive on the communication link at
any given time. Each iDrive requires that b77 is set between 001~254. Only the iDrive with
the correct address will reply to the master with an Acknowledge/Not Acknowledge
message.
1 to many control: PC, PLC or other device can send a 'broadcast' message to all iDrive's on
the communication link by sending to address 000. In this transmission mode all of the
connected iDrive's each receive the same command (regardless of setting b77 on each iDrive )
but do not reply to the master.
2. RS-232 communication: (requires RS232 port device)(Option)
1 to 1 control: PC or PLC or controller controls one inverter (b77 is set to 001~254).
※Note: a . The baud rate (b78) and communication format (b79/b80/b81) of PC (or PLC or other
controller) and iDrive should be the same.
b . The iDrive will validate any modified parameters after the parameters are modified by
PLC or PC etc.
c . Communication protocol: refer to EDX communication protocol description.
d . Parameters b77~b81 cannot be changed in communication mode.

Communication error detection time (s)
b83
Communication error – inverter response
(1) Time-out detection time: 00.0~25.5sec; setting 00.0 sec: disable time-out function.
Default = 00.0sec
*Cannot be changed in communication mode.
(2) Time-out operation selection:
000 : Deceleration to stop (A05 : Deceleration time 1).
001 : Coast-to-stop.
002 : Deceleration to stop (b01 : Deceleration time 2).
003 : Continue operating (Ignore error).
Default = 000
*Cannot be changed in communication mode.
