CAUTION
The hardware limit switch is low active.
For a
0 signal, the drive stops with the OFF3 ramp-down time (p1135), status signal r2684.13 = 1 is set, saved and the
corresponding fault is output. After the fault has been acknowledged, only motion moving away from the hardware
limit switch is permitted.
For a 0/1 signal and valid travel direction, when the hardware limit switch is exited, this is detected and status signal
r2684.13 is set to 0.

Description: Signal for the hardware limit switch in the positive direction of travel.
Recommendation: Set the OFF3 ramp-down time (p1135) so that after the axis reaches the hardware limit switch at maximum velocity,
the braking dis
tance traveled by the axis is not greater than the distance that is available.

CAUTION
The hardware limit switch is low active.
For a 0 signal
the
drive stops with the OFF3 ramp-down time (p1135), status signal r2684.14 = 1 is set, saved and the corresponding
fault is output. After the fault has been acknowledged, only motion moving away from the hardware limit switch is
permitted.
For a 0/1 signal
and valid travel direction, when the hardware limit switch is exited, this is detected and status signal r2684.14 is set to
0.

Description: Sets the maximum velocity for the "basic positioner" function (EPOS).
Dependency: See also: p2503, p2504, p2505, p2506
Note
The maximum velocity is active in all of t

The maximum velocity for the basic positioner should be aligned with the maximum speed/velocity of the speed/velocity

Rotary encoders:
p2571[1000 LU/min] = min(p1082, p1083, |p1086|)[rpm] x p2505/p2504 x p2506/1000
Linear encoders:
p2571[1000 LU/min] = min(p1082, p1083, |p1086|)[m/min] x p2503/10[m]
