Revision December, 2017
Condition: main circuit current is over 1.5 times of the maximum
instantaneous current of the motor.
Causes:
1. Motor has a short-circuit or fault to ground (frame).
2. Motor wiring is wrong.
3. IGBT is abnormal.
4. Parameter setting is wrong.
5. Control command setting is wrong.
1. Check the connection between the motor and servo drive and make
sure that the wire is not short-circuited. Do not expose the metal part of
the wiring. Check if you have followed the wiring sequence of the motor
and servo drive as described in this manual.
2. If the temperature of the heat sink is abnormal, please send the servo
drive back to the distributor or contact Delta. Check if the setting value
is much greater than the default. It is suggested that you reset the servo
drive to the factory default settings and then modify the settings one by
one.
3. Check if the target Torque/Speed/Position commanded changes
greatly. If so, please modify the rate of change in the command or
enable the filter.
DI.ARST
Condition: main circuit voltage exceeds the rated value.
Causes:
1. The input voltage of the main circuit is higher than the rated voltage.
2. Wrong power input (wrong power system).
3. Malfunction of the servo drive hardware.
1. Use a voltmeter to check if the input voltage of the main circuit is within
the rated range (refer to Appendix A Specifications). Use the right
voltage source or connect the regulator in series. Use a voltmeter to
check if the power system complies with the specifications. If not, use
the right voltage source or connect the transformer in series.
2. Check if the input voltage of the main circuit is within the rated range. If
the issue persists, please send the servo drive back to the distributor or
