I I I I I ERRCLR
An option card error can be cleared via the
ERRCLR command. However, the cause of the
error must be eliminated first, otherwise the same
error alarm will occur again. If, in the meantime,
another un-corrected error occurs, then only the
first error will be canceled.
Summary
Error cancellation
Syntax
ERRCLR
The ERRCLR command should only be used in a
subroutine for error handling (see ON ERROR
GOSUB).
NB!
ERRCLR contains the command MOTOR
ON, which automatically turns on the control
again. (The motor is position controlled at the
current position.)
UP TO VERSION 3.00
ERRCLR is only resetting option card errors,
VLT alarms must be reset via a digital input
or the LCP .
NEW
As of Version 3.1x ERRCLR also resets Bit 7 of the
control word of the VLT. Then the VLT messages no
longer need to be deleted.

I I I I I ERRNO
ERRNO is a system variable which is available in
all the programs, and contains the momentary error
code. All error codes are explained in the chapter
Messages and Error Reference.
If, at the time of inquiry no error has occurred, then
ERRNO will contain a 0.
