 Description Note
(bit) 
AC
1: Signals an ongoing positioning job
Pulses are output at device output Q1 or Q2.
also during jog mode or during the braking
ramp and also after S_ is set to 0.

0: Signals that there is no ongoing positioning
job.

E1
Error output
1: in the event of incorrect parameters, such
as:
- FO < FS
(operating frequency < start frequency)
- PF < FS
(jog frequency < start frequency)
No positioning commands if the function
block detects incorrect parameters.
If the function block detects an incorrect
parameter change during an active pos-
itioning job, the step sequence frequency
is reduced according to the braking ramp
and the motor is gently braked to a stop.
