AL086 Regenerative resistor overload
Trigger condition
and cause
Condition: excessive energy in the capacitor of the servo drive is released to the
regenerative resistor causing overload of the resistor.
Cause:
1.
Incorrect selection of the regenerative resistor or no connection to an external
regenerative resistor.
2.
Incorrect parameter settings for P1.052 and P1.053.
3.
Other energy (such as interference) is input to the servo drive or the input
voltage is higher than the allowable rated voltage.
4.
Malfunction of the servo drive hardware.
Checking method
and corrective action
1.
Check the connection for the regenerative resistor and correctly set the values
of P1.052 and P1.053.
2.
Reassess whether the regenerative energy exceeds the value of P1.053.
If the regenerative energy exceeds the set value, replace the regenerative
resistor with a regenerative resistor that has a higher capacity.
3.
Use a voltmeter to measure if the input voltage from the power supply is within
the allowable rated voltage (refer to Appendix A Specifications). If the input
voltage exceeds the rated range, remove the interference source.
4.
Measure the voltage between P3 and
terminals. If it does not match the
displayed DC Bus voltage when you enter monitoring code 14 to P0.002,
the servo drive may be malfunctioning. Send your servo drive back to the
distributor or contact Delta.
5.
If you took the above actions and the issue persists, use a scope with a
differential carbon rod to measure whether the input voltage has high-frequency
signal interference. If there is interference, remove the interference source, and
use the right voltage source or connect the regulator in series.

AL085 Regeneration setting error
Trigger condition
and cause
Condition: regeneration control error.
Cause: regenerative resistor is not operating, but the regenerative voltage remains
at 400V for a period of time.
Checking method
and corrective action
Check the connection for the regenerative resistor, re-calculate the value for the
regenerative resistor, and correctly set the values of P1.052 and P1.053.
If the issue persists, send your servo drive back to Delta.
