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: After changing this parameter, the power must be cycled to enable the new setting.
For serial communications to work, each individual slave drive must be assigned a unique slave 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.
■
H5-02: Communication Speed Selection
Sets the MEMOBUS/Modbus communications speed.
Note: After changing this parameter, the power must be cycled to enable the new setting.
■ H5-03: Communication Parity Selection
Sets the parity used for MEMOBUS/Modbus communications.
Note: After changing this parameter, the power must be cycled to enable the new setting.
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.
Setting 0: Ramp to stop (uses the deceleration time currently enabled)
Setting 1: Fast Stop (uses the deceleration time in C1-09)
Setting 2: Coast to stop
Setting 3: Alarm only (continue operation)
■ H5-05: Communication Fault Detection Selection
Enables or disabled the communication error (CE) detection for MEMOBUS/Modbus communications.
No.
<1> If the address is set to 0, no response will be provided during communications.
