Return-To-Reference-Point - YASKAWA MOTIONPACK-110 Descriptive Information

Parameters #1504, #1704 and #1904 are for X-, Y- and Z-axes, respectively.
NOTE
The setting range covers up to 3200, but, actually, set values below the rapid
traverse feedrate set by #1500, #1700 and #1900.
5.7.3 RETURN-TO-REFERENCE-POINT CREEP FEEDRATE SETTING
(#1505, #1705, #1905) 1__ SET VALUE__ 3200
These parameters are for setting the creep feedrate for returning to the reference point. The
setting unit "1" represents 7.5 mm/min. Parameters #1505, #1705 and #1905 are for the X-,
Y- and Z-axes, respectively.
NOTE
The creep feedrate should be set below approach feedrates set by parameters
#1504, #1704 and #1904.
5.7.4 RETURN-TO-REFERENCE-POINT APPROACH DISTANCE
(#1556, #1756, #1956) I__SET VALUE <90000000
These parameters are for setting the final distance from the detection of the first reference
point pulse, after the dog trips the slowing LS, during the reference-return process.
The setting unit "1" represents 1 pulse (feedback pulse after 4 multipliers).
Parameters #1556, #1756 and #1956 are for the X-, Y- and Z-axes, respectively.
B
Set value = Approach distance (tt m) x A
NOTE
The approach distance must be set longer than the distance required to
decelerate from the approach feedrate to the creep feedrate. The final
. approach distance L is roughly calculated by the following formula:
Where, V, : approach feedrate
a : acceleration/deceleration constant
L= V°2
2a
5.7.5 REFERENCE POINT AREA (#1125) 0<SET VALUE <32767
This parameter sets the area in which the reference point signals (ZPX, ZPY, ZPZ) can be
turned on.
The setting unit "1" represents 0.001 mm. Setting the parameter top (mm) means
a reference point area of _P (mm).
