Check the connection for the regenerative resistor and correctly set the values
1.
of P1.052 and P1.053.
Reassess whether the regenerative energy exceeds the value of P1.053.
2.
If so, replace the regenerative resistor with a regenerative resistor that has a
higher capacity.
Use a voltmeter to measure if the input voltage from the power supply is within
3.
the allowable rated voltage (refer to Appendix A Specifications). If the input
voltage exceeds the rated range, remove the interference source.
Measure the voltage between P3 and
4.
displayed DC Bus voltage when you enter the monitoring code 14 to P0.002,
the servo drive may be malfunctioning. Send your servo drive back to the
distributor or contact Delta.
If you took the preceding actions and the issue persists, use a scope with a
5.
differential probe 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.

Hardware device is in error.
Send your servo drive back to the distributor or contact Delta.
N/A
Condition: too many motor control functions on the servo drive are enabled.
Cause: servo function operational alarm.
If using a filter, see if using this filter is necessary.
Disable the filter if it is not required, such as the low-pass filter (P1.006 - P1.008),
moving filter (P1.068), low-frequency vibration suppression (P1.025 - P1.028),
vibration elimination (P1.089 - P1.094), Notch filter (1
