How to clear the
alarm?
Condition: regeneration control error.
Cause: regenerative resistor is not operating, but the regenerative voltage remains
at 400V for a period of time.
Check the connections for the regenerative resistor, re-calculate the value for the
regenerative resistor, and reset the values of P1.052 and P1.053. If this does not
clear the alarm, send your servo drive back to Delta.
DI.ARST
Condition: when the servo drive detects no regenerative power, but other
regenerative energy (such as interference) is input to the servo drive, or the input
voltage is higher than the permissible rated voltage.
Cause:
Other energy (such as interference) is input to the servo drive or the input
1.
voltage is higher than the permissible rated voltage.
Malfunction of the servo drive hardware.
2.
Use a voltmeter to measure if the input voltage from the power source is
1.
within the permissible rated voltage (see the servo drive specifications).
If the voltage exceeds the rated value, remove the interference source. If you
cannot eliminate the interference, the interference can be consumed with an
external resistor by setting P2.065 bit3 to 0 and P2.094 bit4 to 0.
If the voltmeter detects that the voltage input from the main circuit is within the
2.
permissible rated voltage but the issue persists, then the servo drive may be
malfunctioning.
Use the correct voltage source or connect the voltage regulator in series.
1.
Send your servo drive back to the distributor or contact Delta.
2.
Condition: too many motor control functions on the servo drive are enabled.
Cause: servo function overload warning.
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), or Notch filter (1
