Fault Code Name Possible Causes Solution Level
Err05
Overvoltage
during
acceleration
The input voltage is
too high.
• Check whether the input voltage is too high.
• Observe whether the bus voltage is too high
(normal: 540 to 580 V for 380 voltage input).
5A
The resistance of
the braking resistor
is excessive, or the
braking unit fails.
• Check for the balance coefcient.
• Check whether the bus voltage rises too
quickly during running. If yes, the braking
resistor does not work or its model is
improper:
a. Check whether the cable connecting the
braking resistor is damaged, whether the
cooper wire touches the ground, and whether
the connection is reliable.
b. Check whether the resistance is proper
based on the recommendation and select a
proper braking resistor.
If the resistance of the braking 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.
The acceleration rate
is too short.
Reduce the acceleration rate.
Err06
Overvoltage
during
deceleration
The input voltage is
too high.
• Check whether the input voltage is too high.
• Observe whether the bus voltage is too high
(normal: 540 to 580 V for 380 voltage input).
