3.2.9.1 Recommendations for Analogue Signals Wiring
a) Use a shielded cable as follows: inner wire connects the live signal to the drive analog input ;
shield connects the signal ground to the drive GND.
b) If the signal source output voltage is out of the range 0-3.3V, use a 2-resistor differential
divider, located near the IPS110 I/O connector. Choose the divider resistances as low as
possible, close to the signal source output current limit, to minimize the noise
