NOTE!
Configuration to connect the RS485:

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 cable and separated from the other
wiring (power, command in 110 V / 220 Vac, etc), according to
Distance on page
perpendicularly among them, keeping the minimum separation distance of 5 cm at the
crossing point.
Connect the shield according to the figure below:
Inverter
4. Relays, contactors, solenoids or coils of electromechanical brake installed close to the
inverters 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 HMI (refer to
that connects to the inverter must be separated from the other cables in the installation,
keeping a minimum distance of 10 cm.
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 inverter
grounding connection.
