Pars. 1 to 5 only apply when the Remote Operator is being used as a Modbus or AP ASCII network
gateway. => the Modbus Module Instructions for details.
Remote Operator Reset pushbutton is always enabled.
RS485 Network reset and forced communication trip functions are always enabled.
N.B.!:
Remote Operator Par. 9

normalises the displayed motor current and analog
output for models MCD5-0021B ~ MCD5-0068B. Use Par. 9 in conjunction with Par. 6
Motor
FLC
as follows:
1.
Set Par. 6 to a value 10 times greater than the actual motor nameplate FLC (e.g. for
actual FLC = 4.6 A, set Par. 6 to 46).
2.
Set Par. 9 = 1.
