7 - TROUBLE-SHOOTING USING ERROR CODES
49'1329 e GV3000/SE 7 - 7
How to Access and Read the Results from Torque Self-Tuning:
A result code is entered into vector parameter U.009 with each performance of self-tuning. When a fault
occurs during self-tuning, the display may or may not show a blinking self-tuning fault code.
If more than 1 fault should occur during self-tuning, the front panel will only display the first fault code.
All other faults will be logged into the error log in sequential order including the self-tuning fault code.
Therefore, the error log must be accessed to see any additional faults. There is NO visual indicator to
the user that the error log contains any additional fault codes which occurred during self-tuning.
To Access the Self-Tuning Result code (displayed in Parameter U.009):
Note: This procedure assumes that the password for the second menu list (P.006) has already been entered.
Action Display / Notes
1. Press the PROGRAM key. Display shows 'P.---' - General Parameters.
The PROGRAM LED goes ON.
2.
Press the
⇓
key.
Display shows 'U.---' - Vector parameters.
3. Press the ENTER key. Display shows 'U.000' - the first Vector parameter.
4.
Pressing the
⇑
key or
⇓
key. Step through the
vector parameter list until the display shows
'U.009' - (results of torque control self-tuning).
Display will step through the vector parameter list.
5. Press the ENTER key. Display shows e.g.' 5' - the result of self-tuning.
(Refer to Section 6 for more information on U.009 Torque
Self-Tune Results.)
6. Press the PROGRAM key. Display shows 'U.009' - Returning to vector parameter list.
7.
Press the
⇓
key.
NOTE: After checking vector parameter U.009 for
the self-tuning result code, always check the
error log for additional fault entries.
Display shows 'Err' - Error Log.
Table 7.3 Vector Mode Self-Tuning : Result checking of U.009 value (See also Parameter U.009)
C. Self-Tuning
status Type of Fault Cause and Action
SF U.009 = 1
U.009 = 2 User stop or Emergency
stop/fault during self tuning A user stop has been pressed, or a fault occurred during
self-tuning. (Once the motor stops, clear the faults (both
parameter and hardware) and again perform self-tuning.)
U.009 = 3 Motor or pulse tach direction
reverse The motor is rotating in wrong direction. (Motor rotation
should be in a counter clockwise direction facing the motor
drive end).
If the motor rotation is correct, check that the pulse tach is
wired correctly. (Refer to 49'1327 Sect. 3, control wiring.)
Change controller U and V phases with one another,
if tach wiring is correct.
U.009 = 4 Pulse tach PPR wrong Check that the pulse tach's PPR is one of the four tach
PPR's allowed for usage with the controller.
If not one of the four, replace the tach.
Check that the pulse tach is wired correctly.
(Refer to 49'1327 Section 3, control wiring.)
U.009 = 5 % Motor Magnetising Current
out of range Check that parameters U.002 (Motor Poles), U.003 (Motor
Base Frequency), U.004 (Motor Nameplate Amps), and
U.005 (Motor Nameplate RPM) are set correctly.
U.009 = 6 DC Bus voltage out of range If the line voltage is within limits, contact ROCKWELL
AUTOMATION. Disconnect load from motor.
U.009 = 7 Current limit exceeded Check that parameters U.002 (Motor Poles), U.003 (Motor
Base Frequency), U.004 (Motor Nameplate Amps), and
U.005 (Motor Nameplate RPM) are set correctly.
