- Drive direction UP or DOWN is missing at the end of the travel
o Controller: Delay for switch off the direction!
- Drive direction UP or DOWN is missing at the end of the travel
o Safety circuit, check the door management!
- Drive direction UP or DOWN is missing at the end of the travel
–> Delay time for switching off the contactors to 1500 ms.
You must only have one direction of travel -> In case of a certain controller, which works only with one
direction, please change the parameter setting in the inverter!
- Please change the encoder channels A/B, because the machine rotates in the wrong direction!
- Perhaps it is the wrong type of encoder? -> Menu A4 Motor/Gearbox -> Encoder system
- The number of pulses are wrong? -> Menu A4 Motor/Gearbox -> Encoder Pulses
- The encoder wire is out of order or too long ( >30m) ! -> Please increase the encoder voltage!
- The encoder-shield is not connected to both sides -> Change it immediately!
- The encoder wire is parallel to the motor wire -> Change it immediately!
- The encoder coupling or the encoder is not mechanically fixed with the motor wave -> Please check
– The motor works, but the encoder is out of order or connected incorrectly. -> Control the pin-
ning!

- The encoder-shield is not connected to both sides -> Change it immediately!
- The encoder wire is parallel to the motor wire -> Change it immediately!
- The motor and his metal socket are grounded very poorly -> Change it immediately!
- The frequency inverter is not connected to the ground -> Change it immediately!
- The motorwire-shield is not connected to both sides -> Change it immediately!
- The brake resistor wire-shield is not connected on both sides -> Change it immediately!
- The encoder coupling or the encoder is not mechanical fixed with the motor wave -> Please
check it!
- The frequency inverter has a current limit (full power) -> Power class too low
- Is the car easily running? Have the fixing shoes enough oil? Is the half-load OK?
- The motor works, but the encoder is out of order or incorrectly connected. -> Control the pin-
ning!

:
- After switching ON the inverter, the DC-voltage is too low -> Ground connection of the brake
resistor wire
- After switching ON the inverter, the DC-voltage is too low -> Ground connection of the brake
resistor wire
- After switchinf ON the inverter, the DC-voltage is too low -> The little two fuses into the inverter are
Release Change during the travel – Lift controller error
– Error of the lift controller or wrong settings in the parameter oft the controller / inverter!
Liftbus communication during the travel is out of:
- Wrong Liftbus parameter!
- Wrong Liftbus cable or the shield not connected
