RS485 Communication to DZ using MC1XDZ Advanced Motion Controls • 3805 Calle Tecate Camarillo CA. 93012 • Tel: (805) 389-1935 • www.a-m-c.com AN-002 Introduction The DZRALTE-012L080 servo drive supports RS485 communication in addition to the standard RS232 communication. The drive ships from the factory set for RS232 communication. Default communication parameters are 9600 baud and drive address 63. Configuring the DZRALTE for RS485 In order for the drive to communicate via RS485, the RS485 selection jumper must be installed on the DZRALTE. The J3 jumper is pictured below on the DZRALTE mounted to a MC1XDZ. DZRALTE-012L080 and MC1XDZ Jumper Locations on MC1XDZ Once the jumper is installed, the drive must be power cycled to enable RS485 communications. The default RS485 communication parameters are 9600 baud and address 63 respectively. Configuring the MC1XDZ for RS485 The MC1XDZ mounting card must also be configured properly to support RS485 communication. The factory default is RS232 communication and CAN. To enable RS485 communication, jumpers JF2 and JF3 must be moved so that pins 2 and 3 are shorted together via the jumper. The factory default is RS232 communication with pins 1 and 2 of JF2 and JF3 shorted. Jumper Locations on MC1XDZ Jumper Settings on MC1XDZ DZRALTE communication jumper J3.
