BENTLY 3500/60 163179-01 Monitor card

Autotuning • On the panel press button LOC; LOC is displayed 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 procedure. • 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 information for the failure reason can be read from parameter Diagnosis (7.03). More explanations to the diagnosis messages are available in the chapter Troubleshooting. 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 disappears.

Field current controller

Autotuning • On the panel press button LOC; LOC is displayed 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 procedure. • 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 information for the failure reason can be read from parameter Diagnosis (7.03). More explanations to the diagnosis messages are available in the chapter Troubleshooting. 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 disappears. 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) switches 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.
