Alarm
Code
Name Reason Countermeasure
Failure of the encoder
・ Replace the motor pump
Failure of the controller
・ Replace the controller
Failure of the encoder
・
Replace the motor pump
Failure of the controller
・ Replace the controller
E12
Overspeed
Motor rotation speed exceeded
120% of the maximum rotational
speed
Noise
・ Add a noise filter
Short circuit of the regenerative
resistor
・
Replace the regenerative resistor
Resistance value of the
regenerative resistor is too
small.
・ Check the resistance value of the
regenerative
E13
Regenerative brake overcurrent
Regenerative current exceeded the
specified value.
Motor regenerative energy is too
large.
・
Increase the
acceleration/deceleration time
・ Lighten the load
Power supply voltage is out of
the specification range
・ Check the power supply voltage
in monitor mode [n12: main
circuit voltage], and make it in
the required range
E14
Regenerative brake overload
Overload protection of regenerative
resistor is activated.
During deceleration the braking
force is too large
・ Reduce the parameter value of "
P13 ~ P28: deceleration time
setting"
・ Reduce the value of "P05: Load
command rate at the time of
regeneration", "P06: Regenerative
load ratio command at the time of
deceleration"
The power supply voltage is low
・ Check the power supply voltage
in monitor mode [n12: main
circuit voltage], and make it in
the required range
Re-turn on the power when the
display is not completely
disappeared
・ Re-power when the display is
completely disappeared
E15
Undervoltage
Main circuit voltage becomes less
than DC190V
Failure of the controller
・
Replace the controller
Power supply voltage is high
・ Check the power supply voltage
in monitor mode [n12: main
circuit voltage], and make it in
the required range
Failure of the controller
・
Replace the controller
E16
Overvoltage
Main circuit voltage becomes more
than DC400V
Rapid deceleration in PQ
selection switching
・ Reduce the parameter value of "
P13 ~ P28: deceleration time
setting"
・
Reduce the value of "P05: Load
command rate at the time of
regeneration", "P06: Regenerative
load ratio command at the time of
deceleration"
Load torque is large
・ Replace the motor pump
Defects in motor control due to
the effect of noise
・ Replace the controller
E17
Motor electronic thermal error
Overload protection is activated by
electronic thermal
Defects in motor control due to
the effect of noise
・ Add a noise filter
