8207 TARGET 1 LO
8208 TARGET 1 HI
Target position 1 reference values. See example on page 100.
8209 TARGET 2 LO
8210 TARGET 2 HI
Target position 2 reference values. See example on page 100.
8213 POS DELAY
Stop delay scaling factor at positioning mode 9. Stop time at turning points can be scaled with this
parameter. If the parameter value is zero, then the delay is always zero.
Delay [ms] =
POS DELAY
* 40 / Positioning frequency reference (Hz).
8215 POS MODE
Positioning mode selection.
4 =
RELAT MOVE
1
Selected target position is relative to previous target position. When start command is given, the position
counter is first reset to zero and then corrected with the distance between actual and desired stopping
position. The purpose of this is to prevent the axis to “creep” from its original home position. Correction is
only made, when the previous move has reached the target window area. If two targets are used, make sure
that target reference is changed only at stop-state!
5 =
ABS MOVE
1
Selected target position is absolute. Position counter is not reset when start command is given. This mode is
typically used when the load is moved between two positions.
6 = A
BS MOVE CC
1
Basic operation as in mode 5. Cyclic correction added. Positioning counter is set to the value of home
position parameters 8225
HOME POS LO
and 8226
HOME POS HI
, when digital input 3 (DI3) state changes from
inactive to active state.
7 = A
BS MOVE CC
2
Basic operation as in mode 5. Cyclic correction added. Positioning counter is set to the value of home
position parameters 8225
HOME POS LO
and 8226
HOME POS HI
, when digital input 3 (DI3) state changes from
active to inactive state.
8 =
RELAT MOVE
2
Same as mode 4, except that the position counter starts counting from the value set with parameters 8225
HOME POS LO
and 8226
HOME POS HI
every time when Start command is given. This position mode provides
no position correction possibilities.
9 =
CONT MOVE
1
Selected target is absolute. Continuous move between home and target1 position. Used for example for
spinning wires. A position time delay parameter 8213
POS DELAY
and external frequency reference
parameter 8217
AUX POS CMD
can be defined.
