SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
The target position approach is defined using the parameters of the
selected traversing block.
Table 6-71
Parameters for ”spindle positioning”
Parame-
ters
Parameter text
Value and description
P0080:N
Block number
0... 63
P0081:N
Item
Target position in degrees
P0082:N
Velocity
Search velocity in degrees/min. The velocity is always referred to the load
side, i.e. for a ratio of 4:1 (motor/load), the motor rotates 4 x faster.
P0083:N
Acceleration
override
This allows the acceleration to be influenced, referred to P0103.
P0084:N
Deceleration
override
This allows the deceleration to be influenced, referred to P0104.
P0087:N
Mode
U0W0
Hex
U = target position input
0: Input via traversing block (P0081:N)
1: Input via PROFIBUS–DP; control word XSP (Signal No. 50109)
W = Positioning mode
The behavior when approaching the target position is defined in parame-
ter P0087. The behavior depends on whether the ”spindle positioning”
function is already active and the 1st position was approached or not.
Behavior for nset
active
Behavior if the
1st target position
has already been reached
W = 0 ABSO-
LUTE
(Standard)
The position is ap-
proached with the
actual direction of
rotation
The new target position is ap-
proached through the short-
est distance
W = 1 RELATIVE
Not possible
The new position is incremen-
tally approached.
W = 2 ABS_POS
The position is
approached in the
positive direction.
The new target position is ap-
proached in absolute terms
and in the positive direction
(clockwise rotation)
W = 3 ABS_NEG
The position is
approached in the
negative direction.
The new target position is ap-
proached in absolute terms
and in the negative direction
(counter–clockwise).
