Note: When using a reversing cam, the maximum distance must be set appropriately long.
p2607 EPOS search for reference reference cam present / Ref_cam pres
CU250S_V (EPOS) Access level: 1
CU250S_V_CAN
Can be changed: U, T

Unit group: -
CU250S_V_DP

0
CU250S_V_PN
(EPOS)
Description: Sets whether or not a reference cam is present for the search for reference.
Value = 1: Reference cam present.
Value = 0: No reference cam present.
Dependency: Refer to: p2595, p2597, p2604, p2605, p2606
p2608 EPOS search for reference approach velocity zero mark / v_appr ref_ZM
CU250S_V (EPOS) Access level: 1
CU250S_V_CAN
Can be changed: U, T
(EPOS)
Unit group: -
CU250S_V_DP

(EPOS)
1 [1000 LU/min]
CU250S_V_PN
(EPOS)
Description: Sets the approach velocity after detecting the reference cam to search for the zero mark for the search for reference.
Dependency: If there is no reference cam (p2607 = 0), the search for reference immediately starts with the axis traversing to the
zero mark.
Refer to: p2595, p2597, p2604, p2607, p2609, p2610
Caution: If the reference cam is not adjusted so that at each search for reference the same zero mark for synchronization is
detected, then an "incorrect" axis reference point is obtained.
After the reference cam has been left, the search for the zero mark is activated with a time delay due to internal
factors. This is the reason that the reference cam should be adjusted in this center between two zero marks and the
approach velocity should be adapted to the distance between two zero marks.
Note: The velocity override is not effective when traversing to the zero mark.
p2609 EPOS search for reference max distance ref cam and zero mark / Max s ref_cam ZM
CU250S_V (EPOS) Access level: 1
CU250S_V_CAN
Can be changed: U, T
(EPOS)
Unit group: -
CU250S_V_DP

(EPOS)
0 [LU]
CU250S_V_PN
(EPOS)
Description: Sets the maximum distance after leaving the reference cam when traversing to the zero mark.
Dependency: Refer to: p2595, p2597, p2604, p2607, p2608, p2610
Refer to: F07459
p2610 EPOS search for ref. tol. bandwidth for distance to zero mark / Tol_band to ZM
CU250S_V (EPOS) Access level: 1
CU250S_V_CAN
Can be changed: U, T
(EPOS)
Unit group: -
CU250S_V_DP
Min
(EPOS)
0 [LU]
CU250S_V_PN
(EPOS)
Description: Sets the tolerance bandwidth for the distance to the zero mark
The zero mark is evaluated within the maximum distance between the reference cam and zero mark (p2609) minus
the tolerance bandwidth for the distance to the zero mark (p2610).
