Preparation For Calset - Denso VS-G Series Installation & Maintenance Manual

Checking the 4th-axis position for VS-6556
The internal wiring is visible in the normal condition
as below.

Preparation for CALSET

The VS-G series has no mechanical stop on the 4th and 6th axes.
Press each of the 1st, 2nd, 3rd, and 5th axes manually against the associated
mechanical stop and get the actual position.
Since the 4th and 6th axes have no mechanical stop, you need to mount a CALSET jig
to set a temporary mechanical end for CALSET. Then press the 4th and 6th axes
against those mechanical ends and get those positions. When CALSETing the 6th axis,
you need to press also the 5th axis against the mechanical stop since CALSETing
requires the positional relationship between the 5th and 6th axes.
designated position.
Preparation before carrying out CALSET is finished now.
NOTE: If the step [2.4.2] is omitted, the 4th-axis CALSET position may be
mistaken by one rotation (360°). The internal wiring may be caught in
the crank and broken in such a case.
Mechanical Stops on Axes (VS-G)
On the 1st to 3rd and 5th axes
Mechanical stops provided
When the 4th-axis section is rotated from where it is
as shown on the left, the internal wiring is caught in
the crank and becomes invisible in the left figure.
(The figure below shows the crank at around 250°.)
