Attention! − After changing motion profiles, you should test the automatic se-
quence of motion blocks at reduced speed. The scaled speed func-
tion can be activated via parameter
Speed Override 1236. For the
test, an emergency stop device must be provided in order to be able
to stop the drive immediately in the case of extraordinary move-
ments.
−
If the load moment is changed while motion blocks are being proc-
essed, the target position may not be reached. The deceleration va-
lue set in the motion block is too low in this case in order to stop the
axis at the target position.

4.3.2 VTable
The control software VPlus enables access to the parameters of the frequency in-
verter. The additional program VTable which is included in VPlus enables easy and
comfortable access to all 32 motion blocks at the same time. Motion blocks 1 to 32
are entered in VTable via index 1 to 32. Index 0 can be used in order to set a value
in all motion blocks at the same time.
The parameters in the motion
blocks perform one of three
functions:
[A] Target position incl. speed
[B] Next motion block logic

Setting of digital signal
The parameterized indices for
Mux Input 1252 are independ-
ent from the motion block and
can be used by the multiplexer
for different digital signals [D].
