3.4.2 Analogue input used as digital input
The analogue input is used as digital input in some modes.
This can for example be in Homing mode where the input can be connected to an exter-
nal sensor that detects when the motor have reached the mechanical zero point.
The default trigger level is 7.5V meaning that a voltage above 7.5V is seen as logic high
(active) and a voltage below 7.5V is seen as logic low (passive).
Chaining the input trigger level
The trigger level can be changed by inserting an offset voltage in the offset field/register.
Example:
If 5V is desired as trigger level an offset voltage of 7.5V - 5V = +2.5 must be inserted in
the offset register.
Below is shown how this is done in MacTalk.
