Installation and Connection
NOTE!
In order to use the digital inputs as "active low", remove the jumper between XC1:11 and 12 and
install it between XC1:12 and 13.

Figure 3.20 - Connector XC1 and DIP-switches for selecting the signal type of the analog inputs and outputs
The analog inputs and outputs are factory set to operate in the range from 0 to 10 V; this setting may be
changed by using DIP-switch S1.
Table 3.7 - Configuration of DIP-switches for selecting the signal type of analog inputs and outputs
Signal
AI1 Speed reference (remote)
AI2 No function
AO1 Speed
AO2 Motor current
Parameters related to the analog inputs and outputs (AI1, AI2, AO1, and AO2) shall be programmed according
to the DIP-switches settings and desired values.
Follow instructions below for the proper installation of the control wiring:
1. Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum tightening torque: 0.50 N.m (4.50 lbf.in).
3. Use shielded cables for the connections in XC1 and run the cables separated from the remaining circuits
(power, 110 V / 220 Vac control, etc.), as presented in
cross other cables, it must be done perpendicularly among them, keeping a minimum of 5 cm (1.9 in) distance
at the crossing point.
