6.1 Manufacturer function blocks
 P1 = Number of steps in jog mode = 6000
 TP=1 on duration = 3 seconds
The sample parameters yield the following distance:
 A: Complete distance = P1 = Number of steps in jog mode
 B: Start phase with FS for 0.5 seconds = 100 steps
 C: Acceleration phase with RF= 0.5 Hz/step to reach PF-FS= 800 Hz = 1600 steps
 D: Jog frequency = 1000 Hz with an assumed on time of 3 seconds for TP=1 =
3000 steps
 E: Deceleration phase with BF = 2 Hz/step to reach PF-FS= 800 Hz = 400 steps
 F: P1-(B+C+D+E) = 6000 - 5100 = 900 steps
The run-on distance (phase F) is 900 steps.
The BR function block input is not evaluated during jog mode.
Connecting a pulse output function block
Prerequisites
l
A control relay with 24 VDC must be selected for the pro-
ject.
Evaluation of a pulse output contact
You can use bit outputs AC (positioning job in progress) and E1 (error) to check
whether a positioning or jog mode job has been activated. You can use error output
E1 to check whether your parameters are correct.
Resetting a pulse output function block
To reset (Reset) the pulse output function block, switch the EN bit input from 1 to
0
