COMPAX XX60: electronic gear units
Range of application:
Synchronous angle control, synchronous speed
control, processing while in motion.
Depending on the operating mode, COMPAX XX60
can read and process an external master signal ei-
ther as an alternative to or in conjunction with the
internal master. The external master signal can be
generated by:
! an encoder on a master axis or
! an encoder emulation from COMPAX and/or SV
drive, if these are controlling the master drive.
It is recorded via an interface in COMPAX. The en-
coder pulse assessment is set using parameters.
This makes it possible to run a slave drive unit syn-
chronously to the master unit. A ratio of 1:1, or a ra-
tio in a large setting range (i>1 or i<1) can be se-
lected via parameters. A negative prefix can be used
to signify reversed direction of rotation. COMPAX
XX60 has two parameters for determining standard
ratio factors.
The external master input can be controlled by two
real time inputs (delay time 1ms). In addition to the
enable input, which approves the external master
signal for the controller, there is the option of
switching between the two standard ratio factors.
Example:
Internal reference as dimensional refer-
ence
When the dimension reference is an internal refer-
ence, the internal nominal value specifications are
applied to the datum point of the slave drive. Exter-
nal command pulses are added to the current posi-
tion as relative positioning. External nominal value
specifications do not move the datum point.
absolute positioning to 100mm
external reference value +70mm
relative positioning by +30mm
absolute positioning to 0mm
P0 P1 P2 P3
! Absolute positioning to 100 mm (P1).
! Approval of external nominal value (E16="1"). Unit
travels up to +70 mm in response to impulses from
a command sensor (P2).
! Relative positioning by +30mm (P3)
! Absolute command to datum point (P0)
Master position as dimensional refer-
ence
If the dimensional reference is a master position, the
internal datum point of the slave drive is shifted by
the externally specified nominal value. The internal
reference system is altered (can be corrected again
by a reference journey).
Superimposed movements are possible in this oper-
ating mode. You can carry out positioning relative to
the master position. This can be used to undertake
an internal machining program on a moved work-
piece.

Clarification of this operating mode is provided in the
figure. This figure is based on the positioning cycle
shown previously. Initially, the following axis is refer-
enced to the internal datum point (P0). When the
external nominal value is read, the datum point is
shifted by the value specified.
When using the absolute command for the datum
point (POSA 0), the system is positioned to P0`. P0`
is shifted by the value of the external positioning
relative to P0.
The external nominal value can also be activated
during an internal running move and the internal po-
sitioning superimposed.
Special inputs and outputs:
E14:switching the dimensions reference to internal
reference or master position.
E15:external switching of transmission factor.
E16:engaging external nominal value.
