C.4 MEMOBUS/Modbus Setup Parameters
◆ MEMOBUS/Modbus Serial Communication
This section describes parameters necessary to set up MEMOBUS/Modbus communications.
■
H5-01: Drive Slave Address
Sets the drive slave address used for MEMOBUS/Modbus communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No.
H5-01
<1> If the address is set to 0, no response will be provided during communications.
Each slave drive must be assigned a unique slave address for serial communications to work. Setting H5-01 to any value
besides 0 assigns the drive its address in the network. Slave addresses do not need to be assigned in sequential order, but
no two drives may share the same address.
■
H5-02: Communication Speed Selection
Sets the MEMOBUS/Modbus communications speed.
Note: Cycle the power after changing this parameter to enable the new setting.

■
H5-03: Communication Parity Selection
Sets the parity used for MEMOBUS/Modbus communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No.
H5-03
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
■
H5-04: Stopping Method after Communication Error
Selects the stopping method after a communications error (CE) has occurred.
No.
H5-04
Setting 0: Ramp to stop (uses the deceleration ramp currently enabled)
Setting 1: Fast Stop (uses the deceleration ramp in C1-09)
Setting 2: Coast to stop
Setting 3: Alarm only (continue operation)
