Step 1. Stop the drive.
Step 2. Check the value of the output parameter ARMATURE VOLTAGE (P.289).
If the value is 0: Go to step 5.
If the value is not zero: Go to step 3.
Step 3. Adjust ARM VOLTAGE ZERO (P.205). If ARMATURE VOLTAGE was more
than 0 (positive), adjust ARM VOLTAGE ZERO to a negative value. If it was
less than 0 (negative), adjust ARM VOLTAGE ZERO to a positive value.
Step 4. Repeat steps 2 and 3 until ARMATURE VOLTAGE is zero.
Step 5. Record the final value of ARM VOLTAGE ZERO in table 3.1.
Step 6. Check the value of output parameter ANALOG TACH FEEDBACK (P.291).
If the value is 0: Go to step 9.
If the value is not zero: Go to step 7
Step 7. Adjust ANALOG TACH ZERO (P.202). If ANALOG TACH FEEDBACK was
more than 0 (positive), adjust ANALOG TACH ZERO to a negative value. If it
was less than 0 (negative), adjust ANALOG TACH ZERO to a positive value.
Step 8. Repeat steps 2 and 3 until ANALOG TACH FEEDBACK is zero.
Step 9. Record the final value of ANALOG TACH ZERO in table 3.1.
3.9 Make Final Adjustments
Set the quick start parameters and perform drive self-tuning, as described in the OIM
instruction manual.
When Quick Start and self-tuning are complete, adjust the nominal AC line frequency
and volts as follows. See the OIM instruction manual for information on setting
parameters.
Step 1. The default value of parameter NOMINAL AC LINE FREQ ((P.306) is 60 Hz.
Adjust the frequency to the nominal value of the line frequency for your
application.
Step 2. The default value of parameter NOMINAL AC LINE VOLT (P.307) is 230 VAC.
Adjust the voltage to the nominal value of the line RMS voltage for your
application.
!
ATTENTION: The incorrect setting of the parameters described below
can cause an overspeed condition. These parameters must be set by a
qualified person who understands the significance of setting them
accurately. Verify that the value of these parameters is accurate for your
application. Failure to observe this precaution could result in bodily injury.
