No.
- / real32Defines the maximum position limit.
If the actual position exceeds this value, a stop
command is activated, and Error stop indicated by
74.10 Position control actual status.
Note:
• The deceleration and jerk rates for stopping (75.31
and 75.32 respectively) must be higher than those
used for the base movement. Otherwise the
position limit is ignored and a warning (E205 Fast
Stop configuration) generated.
• The limit is ignored if homing is not done with a
non-absolute encoder (bit 6 or 7 of 86.1 Axis status
= 0).
• The maximum and minimum limits are disabled
if 86.60 and 86.61 are set to the same value, or if
modulo operation is in use (86.18 Modulo range
numerator > 0).

- / real32Defines the minimum position limit.
If the actual position falls below this value, a stop
command is activated, and Error stop indicated by
74.10 Position control actual status.

- / uint32Selects the signal source of the maximum position limit
switch. If the signal is removed, a stop command is
activated, and Error stop indicated by 74.10 Position
control actual status. Running in the forward direction
is prevented.
For the selections, see parameter 86.56 Latch 1 SW
input source.

Enable / uint32Determines whether the backup position value (86.102
Raw axis position backup retain) is used to preset 86.2
Actual position upon the initialization after power-up.
0 = Actual position is read from the selected actual
position source upon initialization.
1 = 86.2 is set according to the value of 86.102 upon
initialization.
