6.1 Manufacturer function blocks
Description Note

FS Start Frequency Integer value range:
0…5000 Hz
FO Operating frequency Integer value range:
0…5000 Hz
RF Frequency change in
the acceleration phase [mHz/step]
Integer value range:
0…65 535
Value for changing the frequency during
the acceleration in 0.001Hz per step.
Example: f-REF = 0-10V
0 = No frequency change
100 = Frequency increased by
0.1 Hz per step
BF Frequency change in
the braking phase [mHz/step]
Value for changing the frequency during
braking in 0.001Hz per step.
Example: f-REF = 0-10V
1000 = Frequency reduction by
1 Hz per step
Integer value range:
0…65 535
P1 Number of steps in jog mode If you only define a very low number of
steps, the start pulse at the TP function
block input must likewise only be very
short. Otherwise the function block will out-
put several pulse sequences that will
cause the distance A to be covered sev-
eral times. In extreme cases generate
short start pulses at TP using a T... timing
relay.
Integer value range:
0…65 535
PF Frequency in Jog mode Integer value range:
0…5000 Hz
Assigning operands
You can assign the following operands to the function block inputs that are numeric
inputs.
Operands Value inputs

MD, MW, MB - Markers x
NB, NW, ND - NET markers x
nNB, nND, nND- NET markers
NET stations n
x
IA - Analog input x
QA - Analog output x
QV - QV - Numeric output of a FB x
You can assign the following operands to the function block inputs that are bit inputs:
