    The ACS 400 drive can receive control information from multiple sources, including digital I/O, analog I/O, keypad, and Modbus fieldbus. To control the ACS 400 via the serial communication channel 1 (Modbus fieldbus), it must be programmed to accept control commands and/or frequency references from this channel. To accept control from serial communications, ACS 400 must be in remote control.
