*1. Do not close the circuit between D24V and D0V terminals. Failure to obey will cause damage to the drive.
*2. Do not close the circuit between HC and D0V terminals. Failure to obey will cause damage to the drive.
*3. Do not set functions that frequently switch ON/OFF to MFDO because this will decrease the performance life of the relay contacts.
*4. Select DIP switch S2 to ON to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
