19 SWNEGLIMACT
By setting this parameter (to 1) the VLT is informed
that the negative software limit switch should be
monitored. Then it is checked whether the target
position is located outside of the permissible
movement range during every movement. In this
case an error message is issued and the drive
control is switched off.
In the positioning mode this means that the corres-
ponding positioning process is not started and the
error can be cleared with the ERRCLR command.
In the impulse mode an error can only be recog-
nized after the limit has been exceeded, thus when
the error message is issued the drive is already
outside of the permissible area of movement. In
this case, it is necessary to move the drive, by
hand, back to the admissible area, and to erase
the error – or in the menu "CONTROLLER" →
"PARAMETERS" → "AXIS" to temporarily turn off
Software limit switch Software limit switch
the corresponding Software limit switch Software limit switch and then Software limit switch
delete the error.

By setting this parameter (to 1) the VLT is informed
that the positive software limit switch is to be mo-
nitored. In this case it is checked whether the tar-
get position is located outside of the permissible
movement range during every movement. If neces-
sary an error message is issued and the drive con-
trol is switched off.
In the positioning mode this means that the cor-
responding positioning process is not started and
the error can be cleared with the ERRCLR
command.

21 KILIM (705)
The Integration limit Integration limit Integration limit Integration limit KILIM indicates the maxi- Integration limit
mum value that can be inputted into the PID filter
via the integral factor. Thus it can be prevented
that due to a high additive error too strong of
counter control is used which would cause the
system to swing.
