3.2.25.2 Output of an analog signal
For this purpose, set code C0540 = 0. The value applied at input DFOUT−AN−IN is converted into a
frequency.
Transfer function
f [Hz] + DFOUT * AN * IN [%] @
No. of increments from C0030

@ C0011
60
Example:
DFOUT−AN−IN = 50 %
C0030 = 3, this corresponds to a number of increments of 2048 inc/rev.
C0011 = 3000 rpm
f [Hz] + 50 % @ 2048

Generating a zero pulse
An artificial zero pulse can be generated for the output frequency.
1. Activate the function through a LOW
® HIGH edge at the input DFOUT−SYN−RDY.
2. A LOW
® HIGH edge at terminal X5/E5 causes the generation of the zero pulse after 360°.
After this, every 360° a zero pulse is generated according to the setting in C0030.
3. The zero pulse is automatically shifted by the value C0545.
)
Note!
This procedure must be done after every mains switching.
3.2.25.3 Output of a speed signal
l Set C0540 = 1.
– This setting only converts the value at input DFOUT−DF−IN into a frequency.
Transfer function
f [Hz] + DFOUT−DF−IN [rpm] @
No. of increments from C0030
60
Example:
DFOUT−DF−IN = 3000 rpm
C0030 = 3, this corresponds to a number of increments of 2048 inc/rev.
f [Hz] + 3000 [rpm] @ 2048

+ 102400 [Hz]
Generating a zero pulse
An artificial zero pulse can be generated for the output frequency.
1. Set input DFOUT−SYN−RDY = edge from LOW
® HIGH.
2. A LOW−HIGH edge at terminal X5/E5 causes the generation of the zero pulse after 360°. After
this, every 360° a zero pulse is generated according to the setting in C0030.
3. The zero pulse can be shifted by +360° via C0545 (65536 inc = 360°).
