7.3 Alarm cause and handling
139
Err18 (IGBT model over-load)
Potential cause Check Handle
Excess the rated load for
continuous duty operation
Check current
Reduce load or replace the servo driver
with bigger one.
Encoder zero point changes Check the encoder zero point
Install the encoder again and adjust the
zero point.
Err20 (EEPROM Error)
Potential cause Check Handle
EEPROM chip is damaged
Turn on the power again and
check
If the error still exists, then replace the
servo driver.
Err21 (Logic circuit error)
Potential cause Check Handle
Control circuit fault
Turn on the power again and
check
If the error still exists, then replace the
servo driver.
Err22 (Power panel and control panel does not match)
Potential cause Check Handle
Power panel and control panel
does not match
Whether to change control
board
Use and power board to match the panel
Err23 (AD conversion error)
Potential cause Check Handle
Current sensor and connector
fault
Check the main circuit
If the error still exists, then replace the
servo driver.
AD converter and analog
amplifier fault
Check the control circuit
If the error still exists, then replace the
servo driver.
Err25 (FPGA verification error)
Potential cause Check Handle
FPGA verification error Re-energize and check
If the error still exists, then replace the
servo driver.
