Shinko ACS-13A Communication Instruction Manual

COMMUNICATION INSTRUCTION MANUAL
This manual contains instructions for communication functions of the ACS-13A.
Serial communication and Console communication cannot be used together.
When performing Serial communication, remove the exclusive cable (CMA) from the USB port of the PC and
loader connector of the ACS-13A.
When performing Console communication, it is not required to remove the Serial communication cables.
However, do not send a command from the master side.

Shielded wire
Connect only one side of the shielded wire to the FG terminal so that current cannot flow to the shielded wire.
If both sides of the shielded wire are connected to the FG terminal, the circuit will be closed between the
shielded wire and the ground. As a result, current will run through the shielded wire and this may cause noise.
Be sure to ground FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted pair
cable.)
Terminator (Terminal resistor)
Communication converter IF-400 (sold separately) has a built-in terminator.
The terminator is mounted at the end of the wire when connecting a personal computer with multiple
peripheral devices. The terminator prevents signal reflection and disturbance.
Do not connect terminator with the communication line because each ACS-13A has built-in pull-up
and pull-down resistors instead of a terminator.
