Condition: regeneration control error.
Cause: regenerative resistor is not operating, but the generative 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 value of P1.052 and P1.053. If
this does not clear the alarm, please send the 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
voltage input is higher than the permissible rated voltage.
Causes:
1. Other energy (such as interference) is input to the servo drive or the
input voltage is higher than the permissible rated value.
2. Malfunction of the servo drive hardware.
1. 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.
2. If the voltmeter detects that the voltage from the main circuit is within
the permissible rated range, but the issue persists, then the servo drive
may be malfunctioning.
1. Use the correct voltage source or connect the voltage regulator in
series.
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.
