C.4 MEMOBUS/Modbus Setup Parameters

H5-11: Communications Enter Function Selection
Selects if an Enter command is needed to change parameter values via MEMOBUS/Modbus communications.
Enter Command on page
No.
H5-11
Setting 0: Parameter changes applied and saved in drive on Enter command input
Parameter changes are applied on Enter command input and saved in EEPROM in the drive if 0900H in the Enter
command is set to 0. Input the Enter command only after completion of all of the parameter changes.
Setting 1: Parameter changes applied immediately and saved in drive on Enter command input
Parameter changes are applied as soon as they are made. The parameter changes are saved to EEPROM in the drive when
an Enter command with 0900H set to 0 is input.

H5-12: Run Command Method Selection
Selects the type of sequence used when the Run command source is set to MEMOBUS/Modbus communications (b1-02,
b1-16 = 2).
No.
H5-12
Setting 0: FWD/Stop, REV/Stop
Setting bit 0 of MEMOBUS/Modbus register 0001H will start and stop the drive in the forward direction. Setting bit 1
will start and stop the drive in reverse.
Setting 1: Run/Stop, FWD/REV
Setting bit 0 of MEMOBUS/Modbus register 0001H will start and stop the drive. Setting bit 1 changes the direction.

H5-17: Operation Selection when Unable to Write into EEPROM
There is normally no need to change this parameter from the default value.
Selects the operation to be carried out when an attempt is made to write data into EEPROM by MEMOBUS/Modbus
communications if writing into EEPROM is not enabled.
No.
H5-17
Setting 0: Cannot write into EEPROM.
Setting 1: Write in RAM only.

H5-18: Filter Time Constant for Motor Speed Monitoring
Sets the filter time constant for monitoring the motor speed from MEMOBUS/Modbus communications and
communication option.
Applicable MEMOBUS/Modbus registers: 3EH, 3FH, 44H, ACH, and ADH
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
No.
