Overview of Software
4.5.9 Service Procedures, Contr Service (7.02)
Armature current controller
(Motor does not turn)
Autotuning
• On the panel press button LOC; LOC is dis-
played in the panel status row.
• Select parameter Contr Service (7.02) = Arm
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.
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:
Arm Cur Reg KP (3.09)
Current controller proportional gain
Arm Cur Reg TI (3.10)
Current controller integral time constant
Cont Cur Lim (3.11)
Continuous current limit
Arm Inductance (3.12)
Armature motor inductance
Arm Resistance (3.13)
Armature motor resistance
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.
Field current controller
(Motor does not turn)
Autotuning
• On the panel press button LOC; LOC is dis-
played in the panel status row.
• Select parameter Contr Service (7.02) = Fld
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.
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:
Field Cur KP (4.03)
Field current controller proportional gain
Field Cur TI (4.04)
Field current controller integral time constant
EMF Reg KP (4.11)
EMF controller proportional gain
EMF Reg TI (4.12)
EMF 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.
Manual Tuning
(Motor does not turn)
Preparation:
• Set Commis Ref 1 (7.15) = 0
• Commis Ref 2 (7.16) = 4096.
• Set Squarewave Per (7.17) = 5s.
The output of the Squarewave Generator (7.18) switch-
es between 0 and 4096. 4096 corresponds to the set
nominal field current (Field Cur Nom 1.03).
• Assign the actual current value (4.02) to analog
output AO1 Ass (6.05) or AO2 Ass (6.06) and
measure it or check the field current with a
current probe.
Activate tuning:
• Set parameter Contr Service (7.02) = Fld Man.
• Switch on and enable the drive via the terminal
block (ON=1, RUN=1) or switch on (I) the drive
with operating panel in the LOCAL mode.
• Main contactor is switched On.
• The field current is flowing, but there is no
armature current. The reference value of the field
current is now following the output limited to 0 to
4096 of the Squarewave Generator (7.18).
Tuning:
• Now set the field current controller with the
parameters Field Cur KP (4.03) and Field Cur TI
(4.04). The procedure can aborted by setting the
parameter Contr Services (7.02) = none or
switching the drive off (ON=0, RUN=0). In this
case, Contr Service (7.02) is reset automatically.
• Main contactor is switched Off.
