4.2 Analog I/O
The FlexDrive
1 analog input on the connector block X3 (demand input)
H
The analog input is not optically isolated from internal power rails, so care must be taken to
avoid earth/ground loops and similar associated problems. The input buffers provide low pass
filtering of the applied voltage.
To minimize the effects of noise, the analog input signal should be connected to the system
using individual shielded / screened cable (a twisted pair cable in the case of differential
operation) with an overall shield. The overall shield should then be connected to the chassis
at one end only. No other connection should be made to the shield.
If the input is unused, then it is advisable to connect it to the AGND pin. Do not leave the input
unconnected (floating).
