If TRAJECTORY TYPE = 1 and the last position was obtained
through jogging, the value of this parameter is a position rela-
tive to that position. If the last position was reached as a result
of a positioning command, then the value of this parameter
specifies a position relative to the last target position (whether
it was reached or not).
If TRAJECTORY TYPE = 2 the application will move in the pos-
itive direction until a touch probe position is defined. If a touch
probe position is already defined the application will move di-
rectly to that position.
A touch probe position is defined as the position at which the
“touch probe switch” input goes high plus the value of TARGET
POSITION.
A touch probe position is cleared by a high signal on the “reset
touch probe position” input. The output “Touch probe position
locked” is high if a touch probe position is defined. If TRAJEC-
TORY TYPE = 3 the application will move in the negative direc-
tion until a touch probe position is defined. If a touch probe
position is already defined the application will move directly to
that position.

This parameter is automatically updated depending on INDEX NUMBER.
19-25 Index ramp up time
Range:
Function:
5,000
[50....100,000 ms]
This setting is relevant during positioning with the current tra-
jectory index. The index ramp up time is defined as the time in
milliseconds it would take to ramp from standstill to the maxi-
mum allowed velocity (P3280).
NB!
This parameter is automatically updated depending on INDEX NUMBER.
19-26 Index ramp down time
Range:
Function:
5,000
[50....100,000 ms]
This setting is relevant during positioning with the current tra-
jectory index. The index ramp down time is defined as the time
in milliseconds it would take to ramp from the maximum allowed
velocity (P3280) to standstill.
NB!
This parameter is automatically updated depending on INDEX NUMBER.
