Installation and Connection
NOTE!
Remove the jumper between XC1:11 and 12 and install it between XC1:12 and 13 to use the digital
inputs as 'Active Low'.

Figure 3.19 - 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 3.6 - DIP-switches configuration for the selection of the signal type for the 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 table 3.7. If control wiring must cross other cables
(power cables for instance), make it cross perpendicular to the wiring and provide a minimum separation
of 5 cm (1.9 in) at the crossing point.
