Overview of Software
Speed controller
Attention: Motor will accelerate twice to 80% of
Base Speed now
Autotuning
• On the panel press button LOC; LOC is dis-
played in the panel status row.
• Select parameter
Contr Service (7.02)
=
Sp
Autotun
and confirm with ENTER.
• Within the next 30 seconds press the (I) button
on the panel. This starts the autotuning proce-
dure.
• Main contactor is switched On and motor will
start turning.
The autotuning procedure is successfully finished if
the panel displays the message
None
.
• Main contactor is switched Off.
After successful autotuning the following controller
parameters are set:
Speed Reg KP (5.07)
Speed controller proportional gain
Speed Reg TI (5.08)
Speed controller integral time constant
If the autotuning procedure failed the alarm message
Autotuning Failed
(A10)
is displayed. Detailed infor-
mation for the failure reason can be read from param-
eter
Diagnosis (7.03)
. More explanations to the diag-
nosis messages are available in the chapter Trouble-
shooting.
Pressing the LOC button on the panel again the
control is switched back to the input/output terminals.
The LOC message in the panel status row disap-
pears.
