8 Inputs and Outputs
8.1 Input circuit
8.1.1 IN A / IN B control inputs
The following logic table applies to the IN A / IN B control inputs:
IN A= 0 AND IN B = 0 => free-wheeling
IN A= 1 AND IN B = 0 => clockwise (positive): Target value, as it comes from the characteristic curve
IN A= 0 AND IN B = 1 => counter-clockwise (negative): Target value multiplied by -1
IN A= 1 AND IN B = 1 => brake / position
The IN A / IN B control inputs are prioritised higher than the position, speed and current target value. If the IN A / IN B control inputs were used
to set “brake”, the software brakes the drive and keeps it at a standstill as long as “brake” is activated.
The control type of the IN A / IN B control inputs can still be changed by the change in rotational direction (this has higher priority).
The “free-wheeling” state has the same meaning as “Motor_Quit” or “Motor_OFF” and is active if IN A AND IN B are set to 0.
If the input parameters Mode 1 and Mode 2 are set to IN A logic and B logic, the drive can be enabled, if the physical IN A / IN B control input
requests = 0 / 0 (= free-wheeling)
OR
the IN 1 / IN 2 inputs request = 0 / 0 (= free-wheeling).
If the input parameters Mode 1 and Mode 2 are set to IN A logic and B logic, and the IN 1 / IN 2 inputs map the IN A / IN B behaviour, the
familiar IN A- / B-Logic can be used:
IN A / IN B = 0 / 0 = enable
IN A / IN B = 1 / 0 = clockwise
IN A / IN B = 0 / 2 = counter-clockwise
IN A / IN B = 1 / 1 = brake / position
