Control Inputs And Outputs (X1) - WEG SCA06 User Manual

Installation and Connection
NOTE
At the end of the useful life, do not dispose of the battery in common garbage, but in a proper place
for batteries.

3.2.4.3 Control Inputs and Outputs (X1)

The control connections (analog inputs/outputs, digital inputs/outputs) must be done to connector X1 of the SCA06.
The typical connection functions are shown in

For the correct installation of the control wiring, 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 in X1 with shielded cable and separated from the other wiring (power, control in 110 / 220 Vac, etc.),
according to Table 3.4 on page
a perpendicular way, keeping the minimum distance of 5 cm (1.96 in) in this point.
4. Relays, contactors, solenoids or coils of electromechanical brakes installed close to servo drives may occasionally
generate interference in the control circuitry. In order 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.
