Wiring Requirements for the I/O Signal Cables
● I/O signals include analog input (AI), analog output (AO), digital input (DI), digital
output (DO) and relay output signals. Before wiring the I/O terminals, disconnect
the main power supply and ensure that the danger indicator of the AC drive is off.
● To avoid interference on the I/O signals, separate the I/O signal cables at least 30
cm from the main circuit cables (three‑phase R/S/T and U/V/W, or single‑phase L1/
L2) and other power cables (or power lines).
● To avoid malfunction of the AC drive and equipment, separate the cable
connecting the relay output terminal from other I/O signal cables by more than 30
cm.
