C.5 MEMOBUS/Modbus Setup Parameters C.5 MEMOBUS/Modbus Setup Parameters u MEMOBUS/Modbus Serial Communication This section describes parameters necessary to set up MEMOBUS/Modbus communications. n 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. If the address is set to 0, no response will be provided during communications. 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. Sets the MEMOBUS/Modbus communications speed. n H5-02: Communication Speed Selection Note: After changing this parameter, the power must be cycled to enable the new setting. n 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 n H5-04: Stopping Method after Communication Error Selects the stopping method after a communications error (CE) has occurred.
Setting 0: Ramp to Stop Using Current Accel/Decel Time Setting 1: Coast to Stop Setting 2: Fast-stop Using C1-09 MEMOBUS/Modbus Communications Setting 3: Alarm Only, Continue Operation n H5-05: Communication Fault Detection Selection Enables or disabled the communication error (CE) detection for MEMOBUS/Modbus communications.
