* Set H5-01 to 0 to disable Drive responses to Modbus communications.
Modbus communication can perform the following operations regardless of the settings in b1-01 and b1-02:
1. Monitoring operation status of the Drive
2. Setting and reading Drive parameters
3. Resetting faults
4. Input multi-function commands

Parameter Name
Selects the speed command (frequency reference)
input source.
0: Operator - Digital preset speed d1-01
1: Terminals - Analog Input Terminal A1
(or Terminal A2 see parameter H3-13)
2: Serial Com - RS-485 terminals R+, R-, S+ and S-
3: Option PCB - Option board connected at 2CN
Selects the Run command input source.
0: Operator - "Hand" and "Off" keys on digital oper-
ator
1: Terminal - Contact Closure on Terminal S1
2: Serial Com - RS-485 terminals R+, R-, S+ and S-
3: Option PCB - Option board connected at 2CN
Selects drive station node number (address) for
terminals R+, R-, S+, S-.*
Selects the baud rate for terminals R+, R-, S+
and S-*.
0: 1200 Baud
1: 2400 Baud
2: 4800 Baud
3: 9600 Baud
4: 19200 Baud
Selects the communication parity for terminals R+,
R-, S+ and S-.*
0: No Parity
1: Even Parity
2: Odd Parity
Selects the stopping method when a communication
error is detected.
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
4: Run at D1-04 - available when
H5-08 = "1: N2 METASYS" or
"2: FLN APOGEE"
Enables or disables the communications timout
detection function.
0: Disabled - A communications loss will NOT
cause a communications fault.
1: Enabled - If communications is lost for more
than the time specified in parameter H5-09, a
communications fault will occur.
Sets the time from when the drive receives data to
when the drive sends data.
Enables or disables request to send (RTS) control:
0: Disabled
1: Enabled
Selects the communication protocol.
0: Modbus
1: N2 (Metasys)
2: FLN (APOGEE)
Determines how long communications must be lost
before a fault is annunciated. Works in conjunction
with parameters H5-05 and H5-04.
* After these parameters are changed drive power
must be cycled before the changes will take effect.
An OR operation is performed between the multi-function command input from the PLC and the command
input from multi-function digital input terminals S3 to S7.
