Modbus communication can perform the following operations regardless of the settings in b1-01 and b1-02:
1. Monitor the operation status of the Drive.
2. Set and read Drive parameters.
3. Reset faults.
4. Input multi-function digital input commands.
5. Control multi-function digital and analog outputs.

Table D.2 Serial Communication Related Parameters
Selects the frequency reference input source.
0: Operator - Digital preset speed U1-01 or d1-01 to d1-17.
1: Terminals - Analog input terminal A1 (or terminal A2 based on
parameter H3-13).
2: Serial Com - Modbus RS-422/485 terminals R+, R-, S+, and S-.
3: Option PCB - Option board connected to 2CN.
4: Pulse Input (Terminal RP)
Selects the run command input source.
0: Operator - RUN and STOP keys on Digital Operator.
1: Terminals - Contact closure on terminals S1 or S2.
2: Serial Com - Modbus RS-422/485 terminals R+, R-, S+, and S-.
3: Option PCB - Option board connected to 2CN.
Selects Drive station node number (address) for Modbus terminals
R+, R-, S+, S-. The Drive's power must be cycled for the setting to
take effect. Set H5-01 to 0 to disable Drive responses to Modbus
communications.
Selects the baud rate for Modbus terminals R+, R-, S+ and S-. The
Drive's power must be cycled for the setting to take effect.
0: 1200 bps
1: 2400 bps
2: 4800 bps
3: 9600 bps
4: 19200 bps
Selects the communication parity for Modbus terminals R+, R-, S+
and S-. The Drive's power must be cycled for the setting to take
effect.
0: No Parity
1: Even Parity
2: Odd Parity
Selects the stopping method when a communication timeout fault
(CE) is detected.
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
4: Run at d1-04
Enables or disables the communications timeout fault (CE).
0: Disabled - A communication loss will not cause a
communication fault.
1: Enabled - If communication is lost for more than 2 seconds, a
CE fault will occur.
Set the delay time from when the Drive receives data to when the
Drive sends data.
Enables or disables "request to send" (RTS) control:
0: Disabled (RTS is always on)
1: Enabled (RTS turns on only when sending)
An OR operation is performed between the multi-function command input from the master device and the
command input from multi-function digital input terminals S3 to S8.
