The “Bipolar Cflct” alarm will be asserted if both of the following are true:
•
One or more of the following digital input functions are configured:
“Forward/Reverse”, “Run Forward”, “Run Reverse”, “Jog Forward”, “Jog
Reverse”.
•
[Direction Mode] is set to “Bipolar” or “Reverse Dis”.
Digital In Status
This parameter represents the current state of the digital inputs. It contains one
bit for each input. The bits are “1” when the input is closed and “0” when the
input is open.
Digital In Examples
