10.1
Run-time errors
A run-time error is an error which occurs in a specific operation of module. It can happen as a result
of an error in the execution of the user's program (such as trying to write to a parameter that doesn't
exist, or trying to divide a value by zero), a misconfiguration or a system error such as processor
overload or watchdog time-out.
•
The action taken when an error occurs may be one or more of the following:
•
User program may be halted or prevented from starting
•
Drive may be tripped on SlotX Error (where X is the slot number) with the sub-trip providing
details of the exact fault.
•
Drive may be tripped on another option module related trip.
•
The ERROR task may be executed (if it exists).
Which of these occurs depends upon the type of error and the setting of the global run-time trip
enable parameter Pr
S.01.014
.
10.2
Drive trip display codes
If the option module detects an error during operation, it will force a trip on the drive. However, the
trip string displayed on the drive will only indicate which slot initiated the trip. The exact reason for
the trip will be indicated in the drive trip code parameters (Pr
10.020
and Pr
10.070
).
The table below shows the possible trips that will be displayed on the drive when a problem is
detected with the option module or when the option module initiates a trip.
Table 10-1 Trip indications
Trip
Description
SlotX HF
The drive has detected that an option module is present but is unable to
communicate with it due to a hardware fault.
SlotX Error
User trip generated by the option module
SlotX Not Fitted
This trip will occur if a drive slot was previously configured with an option
module but on power up, no option module was detected.
SlotX Different
This trip will occur if a drive slot was previously configured with an option
module but on power up, a different option module was detected. Replacing
the option module with another one of the same ID number will not initiate
this trip. The trip will also occur if an option module is installed to a
previously unused slot.
