Trouble-shooting & Common Questions (cont’d)
Code 31 = No. of Teeth of the Pickup Gear
(Feedback Reference Resolution)
Code 34 = 1800
(Maximum Motor Speed, typically 1800 RPM)
•
After the above step, the unit of the set point should be in RPM of the reducer shaft
•
Run the system, and verify the speed of the reducer shaft
•
If the actual speed of the reducer shaft does not match the set point, please verify, calculate
and change the values of the above codes
9. System Needs Help to Start to Rotate:
•
Connect only A1 and A2 terminals on DC motor to ZeDrive A1 and A2 terminals, respec-
tively. Leave F1 and F2 terminals unconnected
•
If a shunt motor is used, check the wiring diagram
10. System Turns at Wrong Direction:
•
Swap A1 and A2 wires should change the direction
11. It Takes Very Long Time to Ramp Up:
•
Check Code 16 for acceleration time
•
Smaller the value, lesser the time for the motor to ramp up. However, it may increase the
chance to damage the pump, due to the quick pressure build-up caused by the restriction
down the stream of the pump
12. It Takes Very Long Time to Slow Down or Stop:
•
Check Code 17 for deceleration time
•
Smaller the value, lesser the time for the motor to stop.
13. Simple Way to Verify Feedback Signal:
•
Power up ZeDrive
•
Click
button
•
Turn the reducer shaft by a wrench
•
Non-zero number should be shown on the top display, whenever the shaft turns
If there always is “0” on the top display, something is wrong related to feedback. Please refer to
“Trouble-shooting” section
14. Tach Reads Incorrectly:
•
Verify the values for the following codes:
Code 61 = 1
(“Primary Active Output Format” set to “Master”)
Code 20 = 1800 / Gear Ratio (Maximum Reducer Speed in RPM)
Code 22 = 1800 / Gear Ratio (Maximum Reducer Speed Display in RPM)
Code 31 = No. of Teeth of the Pickup Gear
(Feedback Reference Resolution)
Code 34 = 1800
(Maximum Motor Speed, typically 1800 RPM)
