Configuration to connect the RS485:
S1.3 = ON and S1.4 = ON: terminal RS485 ON.
„
S1.3 = OFF and S1.4 = OFF: terminal RS485 OFF.

Any other combination of the switches is not allowed.
For the correct connection of the control, use:
1) Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2) Maximum torque: 0.5 N.m (4.50 lbf.in).
3) Wiring of the plug-in module connector with shielded cables separated from the
other wiring (power, command in 110 V / 220 Vac, etc.), according to
Cable Separation
perpendicularly, keeping the minimum separation distance of 5 cm (1.97 in) at the
crossing point.
Connect the shield according to the figure below:
4) Relays, contactors, solenoids or coils of electromechanical brakes installed close to
the drives may occasionally generate interference in the control circuitry. To eliminate
this effect, RC suppressors (with AC power supply) or freewheel diodes (with DC
power supply) must be connected in parallel to the coils of these devices.
5) When using the external HMIR (refer to
connects to the drive must be separated from the other cables in the installation,
keeping a minimum distance of 10 cm (3.94 in).
6) When using analog reference (AI1) and the frequency oscillates (problem of
electromagnetic interference), interconnect the GND of the connector of the plug-in
module to the drive grounding connection.
