10 Troubleshooting
The following guidelines will help you to troubleshoot some of the most common fault messages that appear during
the initial installation of the RBPC:
10.1 Backwards movement detected
If this fault occurs while doing the initial setup it means that the resolver is not set to turn in the correct direction.
Change the direction of the resolver signals in the supervisor menu. This feature can be changed in the
Supervisor
Menu → Resolver Settings → Set Work Direction
.
If this fault occurs after the setup and running of the press is complete, it could be cause by a loose gear on the
resolver. A temporary fix would be to increase the Backwards detection window. This is done in the
Supervisor Menu
→ Resolver Settings → Movement Detection
.
Please refer to the
Resolver settings
section of the RBPC User's Manual for further details and step-by-step
instructions.
10.2 Resolver check not found
This fault could occur because the resolver offset or zero position is not set correctly. To set the resolver offset go to
the
Supervisor menu → Resolver settings → Resolver offset
.
This fault also could be generated because the Proximity switch, which is used for the top dead center check,
(resolver check) is not being activated properly. Check the proximity switch and input on J7-3. There are small LED
above the inputs used to verify activation of the sensor.
Please refer to the
Resolver settings
section of the RBPC User's Manual for further details and step-by-step
instructions.
10.3 Brake time exceeded
This fault is generated because the stopping time of the press exceeds the programmed value in the RBPC. Check
the stopping time of the press using the Brake Wear hot key and change the parameters of the brake settings in the
supervisor menu to correspond to the viewed value. This can be done through the
Supervisor menu → Braking
settings
. View section 14 of the User’s Manual on all the details for the brake settings.
Please refer to the
Braking settings
section of the RBPC User's Manual for further details and step-by-step
instructions.
