A5.2
Drive does not start running
- Spring-loaded safety brake does not open.
- Main contactor does not switch on.
Error No.
2,7,15-19,22-25
30
and
31
Range limit for parameters is achieved:
- Change the parameter value according to the reference.
32
Stop input !
Driving command has been fed although one parameter has still been changed.
0
Press any key to end parameterization.
11
RV1 or RV2
Error in the PLC: Both direction sets are fed at the same time.
12
RV1/RV2 is missing
Error in the PLC or line break:
- A driving command is fed without direction set.
29
Power stage
In case of a start-up trial, no voltage is fed at the motor:
- There should be no contactor between motor and power stage.
- The main contactor is to be switched on by means of contact "RB" or if a
driving command is fed at the latest.
A5.3
The drive switches off when accelerating or does not start running
- Brake opens
- Main contactor closes
8
Wrong direction
a) Drive turns up quickly to maximum speed and switches off after 2 seconds.
-> Exchange encoder connection ET2 and ET3.
b) Counter balance pulls cabin to the wrong direction.
- Check in general whether drive, brake and main contacter are okay.
9
No starting
The controller does not receive a encoder signal within the monitoring
time /ZA-INTERN/T_GUE.
a) Motor turns up quickly to maximum speed and switches off
-> Check the connection of the encoder (see A5.6).
b) Motor does not move, motor noise can be heard
->Motor blocks?
14
Encod. dop out
Speed transmitter signal (ET2/ET3) has broken down.
- See A5.6 "Checking the encoder".
35
N_PROG >> N_REAL
Drive is not able to follow programed value.
- check whether the correct encoder type has been set in
/INSTALLATION/GEBER (bar number probably to high).
A5.4
Drive switches off when decelerating
14
Encod. drop out
Speed encoder signal (ET2/ET3) has broken down.
- See A5.6 "Checking the encoder".
36
N_PROG << N_REAL
Drive does not decelerate:
- Brake winding is probably not connected correctly.
- /DECELERATING/A_MAX to high.
A5.5
Drive switches to trouble when stopping
37
MTR still rotate
Motor still turns although the mechanical brake should have come in before long.
Contact "MB" does not directly connect the mechanical brake.
