MEMOBUS/Modbus Parameters

H5-01: Drive Node Address
n
This parameter tells the PLC what the node address is for the individual drive.
No. Name
H5-01 Drive Node Address
*If the address is set to 0, no response will be provided during communications.
For serial communciations to work, each individual slave drive must be assigned a unique node address. Setting H5-01 to any value besides 0 assigns the
drive its address in the network. Slave address don't need to be assigned in sequential order, but each address needs to be unique so that no two drives
have the same address. The power to the drive needs to be cycled after setting the address for the node address to take affect.
H5-02: Communication Speed Selection
n
H5-03: Communication Parity Selection
n
These parameters set the communication speed and the parity.
No. Name
H5-02 Communication Speed Selection
H5-03 Communication Parity Selection
Detailed Description
Parameters H5-02 and H5-03 should be set according to the network specifications run by the master controller. Because the power to the drive needs to
be cycled in order for these parameter settings to take affect, the application will have to be stopped to change these settings.
H5-04: Stopping Method After Communication Error
n
Tells the drive how it should stop the motor when a communication error occurs.
No. Name
Stopping Method After
H5-04
Communication Error
H5-05: Communication Fault Detection Selection
n
Enables or disables the communications time-out fault (CE).
No. Name
Communication Fault Detection
H5-05
Selection
If H5-05 is set to 1, a fault will occur if the master controller does not receive a response from the drive after two seconds. The power to the drive needs
to be cycled for the setting in H5-05 to take affect.
H5-06: Drive Transmit Wait Time
n
Sets how long the drive should wait to send a response after it receives data.
No. Name
H5-06 Drive Transmit Wait Time
Drive power needs to be cycled for the setting in H5-06 to take effect.
332
Description
Selects drive station node number (address) for MEMOBUS/Modbus terminals R+, R-, S
+, S-.
Cycle power for the setting to take effect.
Selects the baud rate for MEMOBUS/Modbus terminals R+, R-, S+ and S-.
Cycle power for the setting to take effect.
0 : 1200 bps
1 : 2400 bps
2 : 4800 bps
3 : 9600 bps
4 : 19200 bps
5 : 38400 bps
6 : 57600 bps
7 : 76800 bps
8 : 115200 bps
Selects the communication parity for MEMOBUS/Modbus terminals R+, R-, S+
and S-.
Cycle power for the setting to take effect.
0: No parity
1: Even parity
2: Odd parity
0: Ramp to stop (decelerates according to C1-02)
1: Coast to stop2: Fast-Stop3: Alarm only
0: Disabled - A communication loss will not cause a communication fault.
1: Enabled - If communication is lost for more than two seconds, a CE fault will
occur.
Description
Set the delay time from when the drive receives data to when the drive sends data.
