Chapter 10 Troubleshooting
AL085：Regeneration error
Causes
Choose wrong
regenerative resistor or
does not connect to
external regenerative
resistor.
Parameter P1-53 is not
set to zero when the
regenerative resistor is
not in use.
Wrong parameter setting
AL086：Input voltage is too high
Causes
The servo drive detects
no regenerative power,
but other regenerative
energy (such as
interference) is input to
the servo drive, or
voltage input is higher
than the permissible
rated voltage.
Servo drive (hardware)
malfunction
AL095：The servo drive does not connect to external regenerative resistor
Causes
The input of regenerative
resistor capacity is over 0
and the servo drive does
not connect to external
regenerative resistor
Checking Method
Check the connection of
regenerative resistor.
Check if parameter P1-53 of
regenerative resister is set to zero.
Check the setting value of
parameters P1-52 and P1-53.
Checking Method
Use a voltmeter to measure if the
input voltage from the power
source is within the permissible
rated value (see the servo drive
specifications). If the voltage
exceeds the rated value, please
remove the interference source.
Check if the issue persists when
the voltmeter detects that the
voltage from the main circuit is
within the permissible rated
range.
Checking Method
1. Check if it is connected to
regenerative resistor.
2. Check if the setting value of
P1-53 is 0.
Corrective Actions
Calculate the value of the
regenerative resistor again and
correctly set the values of P1-52
and P1-53. If the issue persists,
please send the drive back to the
distributors or contact Delta.
Set parameter P1-53 of
regenerative resistor to zero when
it is not applying.
Correctly reset the values of P1-52
and P1-53.
Corrective Actions
Use the correct voltage source or
connect the voltage regulator in
series.
Please send the drive back to
distributors or contact Delta.
Corrective Actions
1. If wishing to apply regenerative
brake, please connect to
external regenerative resistor.
Then, check if the setting of
P1-53 is correct.
2. If not applying to regenerative
brake, please set P1-53 to 0.
3. If the issue persists after
conducting the above two
steps, please send the drive
back to distributors or contact
Delta.
