Fault

Level
Err05
Overvoltage
during
acceleration
● The input voltage is too
high.
● The regeneration power
of the motor is too high.
● The braking resistance is
too large, or the braking
unit fails.
● The acceleration rate is
too short.
1. Check whether the input voltage is too
high. Observe whether the bus voltage is
too high (normal: 540–580 V for 380 voltage
input).
2. Check for the balance coefcient.
3. Check whether the bus voltage rises too
quickly during running. If yes, the regen.
resistor does not work or its model is
improper:
● Check whether the cable connecting the
regen. resistor is damaged, whether the
cooper wire touches the ground, and
whether the connection is reliable.
● Check whether the resistance is proper
based on the recommendation in chapter
4 and select a proper regen. resistor.
● If a braking unit is used, check whether
the braking unit works properly and
whether the model is proper.
4. If the resistance of the regen. resistor is
proper and overvoltage occurs each time
when the elevator reaches the target speed,
decrease the values of F2-01 or F2-04 to
reduce the curve following error and prevent
overvoltage due to system overshoot.
5. Check whether the acceleration/
deceleration rate is too short when Err05 and
Err06 is reported.

Err06
Overvoltage
during
deceleration
● The input voltage is too
high.
● The braking resistance is
too large, or the braking
unit fails.
● The deceleration rate is
too short.
5A
Err07
Overvoltage at
constant speed
● The input voltage is too
high.
● The braking resistance is
too large, or the braking
unit fails.
5A
Err08
Maintenance
notication
period reached
The elevator is not maintained
within the notication period.
● Power-off and maintain the elevator.
● Disable the maintenance notication
function by setting F9-13 to 0.
● Contact us or directly our agent.
5A
Err09 Undervoltage
● Instantaneous power
failure occurs on the input
power supply.
● The input voltage is too
low.
● The drive control board
fails.
● Check whether the external power
voltage is too low.
● Check whether the power fails during
running.
● Check whether wiring of all power input
cables is secure.
● Contact us or directly our agent.
