AL017 Abnormal EEPROM
Trigger condition
and cause
Checking method
and corrective action
Condition: temperature of IGBT is too high.
Cause:
The load is over the rated range and the servo drive is in a persistent overload
1.
condition.
Servo drive has a short-circuit or fault to ground (frame).
2.
Check if the motor is overloaded or over-current. Then, try increasing the
1.
motor's capacity or reducing the load.
Check if the wiring of servo drive output is correct.
2.
DI.ARST
Condition: error occurs when DSP accesses EEPROM.
Cause:
1. Parameter writing error or the value exceeds the permissible range. This error
occurs when parameters are restored to the default and servo drive type is
incorrect.
2. Data in ROM is damaged or there is no data in ROM. This occurs when the
system is in Servo On status. If this alarm occurs, send your servo drive back
to the distributor or contact Delta.
Press the SHIFT key on the panel and "EXGAB" is displayed.
X = 1, 2, 3
G = Group number of the parameter
AB = Parameter number in hexadecimal format
If the panel displays E320A, this is parameter P2.010. If E3610 is displayed,
this is P6.016. Check the value for the displayed parameter.
Press the SHIFT key to display the parameter code. If this alarm occurs when
1.
power is supplied to the drive, it means a parameter value has exceeded the
range. Modify the value and then cycle the power. If the error occurs during
normal operation, it means an error occurred when writing the parameter.
Use DI.ARST to clear this alarm.
Press the SHIFT key on the panel and E100X is displayed. If this alarm occurs
2.
while parameters are being restored to the default, it means the servo model
type setting is incorrect. Please correct it.
Press the SHIFT key on the panel and E0001 is displayed. If this alarm occurs
3.
while power is being supplied, it is usually because the data in ROM is
damaged or there is no data in the ROM. Send your servo drive back to the
distributor or contact Delta.
