SFC commissioning, rotational
drive without encoder
Prerequisite:
• The motor specified for the application is connected.
• Control terminals wired according to
terminal assignment 2,
see page 3-14.
•A K
EYPAD KP200 or a PC with DRIVEMANAGER (version V2.3 or
higher) is connected. For operation see section 4.6 and 4.7.
Attention: Make sure the rotating drive in your machine cannot cause
any damage (e.g. overrunning its stop limit) during commis-
sioning.
Step Action Comment
1
Connect the KEYPAD or the PC to the
inverter module and switch on the
power to the inverter module.
After power-up the inverter module per-
forms a self-test (lasting approx. 1... 3
s).
2
Check that your drive can be run at
the rotating field frequency and with
the ramps as per the factory setting.
Rotating field frequency (FMAX) = 50Hz
with reference (R1) = 10 V
Acceleration ramp = 20 Hz/s
1)
Deceleration and stop ramp = 20 Hz/s
1)
If this is not possible, change the
parameters shown adjacent.

Close ENPO contact, set parameter
163-ENSC to START.
Automatic motor identification started,
lasts approx. 3-4 min., then automati-
cally jumps to STOP.
6
Select parameter 300-CFCON, set to
SFC, confirm.
Control mode:
Sensorless Flux Control (SFC) selected
7
Back-up the setting in subject area
_15FC with parameter 150-SAVE.
1) Factory setting from BG1
to BG5 (15 kW ) = 20 Hz/s, as
from BG6 (22 kW) to
BG8 = 5 Hz/s
Remember to
save the set-
ting.
