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 out-
side 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 –

By setting this parameter (to 1) the VLT is informed
that the positive software limit switch is to be moni-
tored. In this case it is checked whether the target
position is located outside of the permissible move-
ment range during every movement. If necessary
an error message is issued and the drive control 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.
In the impulse mode an error can only be recogni-
zed 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

The Inte Integration limit Inte Inte gration limit gration limit gration limit KILIM indicates the maximum
Inte gration limit
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.
