4.1 Introduction
This section describes the various digital and analog input and output capabilities of the
MintDrive
II
, with descriptions of each of the connectors on the front panel.
The following conventions will be used to refer to the inputs and outputs:
I/O Input / Output . . . . . . . . . . . . . .
DIN Digital Input . . . . . . . . . . . . .
DOUT Digital Output . . . . . . . . . . .
AIN Analog Input . . . . . . . . . . . . .
AOUT Analog Output . . . . . . . . . . .
CH Encoder channel . . . . . . . . . . . . .
4.2 Analog I/O
The MintDrive
II
provides as standard:
H
1 analog input on the connector block X3 (demand input)
H
1 analog input on the connector block X4
H
2 analog outputs on the connector block X4
The analog inputs are 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, each analog input signal should be connected to the system
using individual shielded/screened cable (a twisted pair cable in the case of the differential
inputs) 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 any inputs are unused, then it is advisable to connect them to the AGND pin. Do not leave
the inputs unconnected (floating).
