711 VLT local mode
VLT MANUAL
712 Positive direction
POS. DIRECTION
MG.50.P3.02 - VLT is a registered Danfoss trademark
Positioning Controller
Default Range
value
0 0 = Pos control
1 = VLT control
1 -2 = right rotation
-1 = left rotation
1 = right rotation
2 = left rotation
Description
P722 motor/encoder gear ratio denominator
For VLT 5000 Flux the following
parameters influence the result and must
be set correctly beforehand:
P205 maximum reference rpm
P713 encoder type
P714 encoder resolution
P721 motor/encoder gear ratio numerator
P722 motor/encoder gear ratio
denominator
NB! If you change any one of these para-
meters you should prompt a recalculation,
since the optimum value of 702, 703, 704
and 707 will have changed.
By setting this parameter to 1 the VLT
changes to setup "2" Manual running of the
VLT is now possible.
Here you specify which encoder direction
is considered positive. If you change this
setting the current actual position (P795)
will also change sign.
1 = standard, position is counting positive
when the drive is running forward.
-1 = position is counting negative when the
drive is running forward.
2 = as "1", but with opposite sign of the
reference to the drive. This can be
used as alternative to swapping two
motor phases if direction of motor
rotation is wrong.
-2 = as "-1", but with opposite sign of the
reference to the drive. This can be
used as alternative to swapping two
motor phases if direction of motor
rotation is wrong.
