The causes of often occurred fautls:
Error Code Name Causes
Err.11
Voltage protection--controlling power shortage
While DSP is low voltage, inhibit process of EEPROM and display
error.
Err.12 overvoltage protection Occurs while voltage is over AC 260V.
Err.13
Voltage protection--main power shortage
Occurs while voltage is lower than AC 170V or connection of single
phase power isnot correct.
Err.18
Flyback overload protection
Occurs while DC-bus is over DC400V(AV283V), flyback rate is 100%,
the bench-mark of flyback limit is DC 368V, 0%, and DC 395V, 85%.
Err.20
Err.48
Err.21
Protection of faults of encoder A and B
Protection of fault of Z phase of encoder
Protection of faults of encoder communication
Verify whether connector of SIG encoder correctly connect to driver.
Verify connection of male and female connector of encoder cable is
correct.
Err.14
Err.99
Excessive current protection
Excessive current protection of driver hardware
Verify whether motor power(U,V,W) is short circuit or loose.
