Tune Interrupted
The drive was prevented from completing an auto-tune, because either the drive enable or the drive run signals were
removed.
Recommended actions:
•
Ensure the drive enable signal is active for the entire auto-tune. This can be checked using
Sequencer Input and
Output Indicators
(P1.11)
•
Ensure a run signal (Run Forward, Run Reverse or Run) is active for the entire auto-tune. This can be checked using
Run & Direction Indicators
(P1.12)
•
If these signals are supplied by a digital input, check the states of the IO using
Digital IO Indicators
(P1.25)
E020
Motor Temp
The drive has estimated that the motor has become too hot based on the
Motor Rated Current
(P3.01) and
Thermal
Protection Action
(P3.21).
Motor Thermal Percentage
(P1.22) displays the motor temperature as a percentage of the maximum value. The error
occurs when this parameter reaches 100 %.
Recommended actions:
•
Ensure the load is not jammed / sticking
•
Check the load on the motor has not changed
•
Ensure the motor rated current is correct.
E021
Drive Temp 1
An IGBT junction over-temperature has been detected.
Recommended actions:
•
Check enclosure temperature
•
Check enclosure / drive fans are still functioning correctly
•
Clean the fan filter if being used
•
Check enclosure ventilation paths
•
Check enclosure door filters
•
Increase ventilation
•
Reduce duty cycle
•
Increase acceleration / deceleration rate parameter values
•
Reduce motor load
•
Ensure all three supply phases are present and balanced
•
Confirm the drive is correctly sized for the application
•
Use a drive with larger current / power rating
E023
Drive Temp 2
A power stage over-temperature has been detected.
Recommended actions:
•
See Drive Temp 1
E027
Drive Temp 3
A D.C. bus component over temperature has been detected.
Recommended actions:
•
See Drive Temp 1.
E028
An In 1 Current
A current loss was detected in T2 analog input 1 and the input type is set to 4-20 mA Error (6). Loss of input is detected if
the current falls below 3 mA.
Recommended actions:
•
Check control wiring is correct
•
Check control wiring is undamaged
•
Check T2
Analog Input 1 Type
(P6.01)
•
Check the current signal is present and greater than 3 mA
