3-22 Getting Started
3. Checking the Auto Update feature enables the
Encoder Counts gauge.
4. Verify the Number of Poles and make sure the value
entered is correct for the motor you are using. The
default value is 4.
5. On the Amplifier Status Now! screen (Figure 3-3),
verify the data entered is complete. A percentage of
the Continuous Current Limit will be used to drive
the motor shaft.
6. Select the Check Encoder Counts button. The
motor shaft should rotate one revolution.
The Encoder Check screen should display
Configured Counts/Rev. and Measure Aprox.
Counts/Rev. As the shaft rotates the Encoder
Counts gauge reflects rotation and encoder counts.
7. If the motor shaft did not rotate, use the Motor
Command tuning slide to apply more current. Select
Check Encoder Counts again. The amount of
current applied is a percentage of the Continuous
Current Limit . Tune and select Check Encoder
Counts as necessary.
(For a more precise method of measuring
Approx. Counts, see Manual Encoder
Check in next section.)
8. Successful completion of the Encoder Checking
routine is signified by:
a. The near match of data displayed in Configure
Counts/Rev. and Measure Approx. Counts/
Rev. boxes.
b . The Index Sensed indicator alternates between
red and green as the index pulse is detected.
c. The Index captured indicator turns green to
signify that an index pulse was detected after one
full revolution of the shaft. Also, there is proper
synchronization of the index pulse to the A and B
encoder pulses.
