Example with Normal mode:
Set parameter:FO = 3000 Hz, FS = 200 Hz, RF = BF = 1000
Result: n

= n

Example with Normal mode:
1000 = Frequency change by 1 Hz per step
P1: Number of pulses in Jog mode,
Jog mode
Jog mode (TP = 1) can be activated for diagnostics and testing purposes.
For this coil PO..TP is actuated. The following parameters are required for
Jog mode:
The behavior of the function block in Jog mode varies according to the length
of the signal at coil PO..TP:
1. TP on duration < 0.5 seconds:
The function block generates at the device output the number of pulses
defined at P1 with the starting frequency defined at FS.
see range “A“ in
2. TP on duration
≥
0.5 seconds:
The function block generates at the device output the start frequency set at
FS for 0.5 s and then accelerates up to the Jog frequency PF.
The pulse operation can be interrupted at any time by a 0 signal at the
TP input.
If Jog mode is deactivated (TP = 0) while a pulse sequence is output at the
device output with a Jog frequency (time point E), the pulse sequence is
continuously reduced to the start frequency (braking phase) see Range B in
