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
5AThe regen. resistance is too
large, or the braking unit fails.
◆
◆
Check whether the bus voltage rises too
quickly during running. If yes, the braking
resistor does not work or its model is im-
proper:
◆
Check whether the cable connecting the
braking resistor is damaged, whether the
cooper wire touches the ground, and wheth-
er the connection is reliable.
◆
Check whether the resistance is proper
based on the recommendation in chapter 4
and select a proper braking resistor.
◆
If a braking unit is used, check whether the
braking unit works properly and whether
the model is proper. 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.
