4.2 Analog I/O
The FlexDrive
II
provides as standard:
H
1 analog input on the connector block X3 (command input)
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).
