Err16 (Motor over-heat)
6.2 The reason and handling of alarm
Potential cause
Excess the rated load for
continuous duty operation
Encoder zero point changes
Check
Check the load factor and the
rise in temperature of motor
Check the encoder zero point
Handle
Reduce load or replace the servo driver
with bigger one.
Install the encoder again and adjust the
zero point.
Err17 (Overload of brake average power)
Potential cause
The voltage of input AC power
supply is too high
Regeneration energy too large
Check
Check the voltage of power
supply
Check the regeneration load
factor
Handle
Use correct power supply according with
the specifications.
z Slow down the starting and
stopping frequency.
z Increase acceleration /deceleration
time setting.
z Reduce the torque limit.
z Decreasing the load inertia.
z Replace the servo driver and
servomotor with bigger ones.
Err18 (IGBT model over-load)
Potential cause
Excess the rated load for continuous
duty operation
Encoder zero point changes
Check
Check current
Check the encoder zero
point
Handle
Reduce load or replace the servo driver
with bigger one.
Install the encoder again and adjust the
zero point.
Err20 (EEPROM Error)
Potential cause
EEPROM chip is damaged
Check
Handle
Turn on the power again If the error still exists, then replace the
and check
servo driver.
