Conversion Stage 3 to Stage 4
1. Machine parameters
A new machine parameter MP 17 which pennits optional assignment of the MTB keys on the
manual panel with
Ne or PlC fUnctions has been introduced in Stage 4.
The parameter can
be assigned values between 0 and 15. The value specifies the number of Ne
keys. Ifcompatibility with version :r;£ Stage3 is tobe retained, the number 10 must be entered in these
parameters. The upper
10 keys ofthe manual panel are then assigned Ne functions, and the other
keys set bits in the PlC.
2. Write protection
There are lINo write protection switches on the control. One is accessible on the front panel of the
CP/MEM module (machine parameters). The second is mounted on the PlC board (PlC program).
If one of the switches or both switches is or are not switched to write protection, the control
signals this after power-up
or after the Reset key on the power supply unitis pressed. One or both
corresponding error messages are displayed, with softkey -PRESS TO CONTNUE" which must
be pressed (see Figure). After acknowledgment by the softkeys, the control reverses to group
operating mode Machine. If both switches are active, the control reverts directly
to group operating
mode MACHINE

Description Stage 4 Chapter 1
Definition, function:
CC lOOM
User Manual
Simulation provides graphic support before execution. It offers the possibility of checking and
optimizing the part program. The individual work steps of thE? part program are simulated in true-
to-~fe manner. The user sees the tool traverse movements with the current speed (GO,G1). The
speed can be varied via potentiometers.
The programmed contour becomes visible step by step from the workpiece which is displayed in
the correct position (zero shift, actual values), Note that the contour is produced from the traverse
paths
of the tool canter-point path. It is not a direct contour description. The control checks the
program for operability, collision risks and technological boundary conditions. The function is
available in group operating mode AUTOMATIC. The movements of the tool canter point are
visualized in a 2 112-0 display. The axes of the selected working plane are represented in a 2-D
image, whilst the third axis perpendicular
to the working plane is represented on a vertical "scale"
displayed next to the 2-D image.
Simulation always starts with the current machine position; traversing
of the machine is not
possible.
The simulation speed can be switched over at any time between the programmed speed (status:
NORMAL) and immediate display (without interpolation).

Definition:
The E axis can be rotated continuously. After one revol,~,Jtion (360°). the actual value is set to O.
Programmed traverse movements with angle> 3600 are subjected to operation -modulo 360-
and executed. The direction of rotation is detennined by the sign of the axis values. Interpolating
spindle mode of the E
axis (10 -3600): maximum 1 revolution. Continuous rotations are possible.
Preconditions:
.. The E axis must be defined as a rotary axis. Machine parameter 1 must be set to "N" for
this purpose (4th axis = rotary axis).
... Machine parameter 15 must be set to "Y". The axis position display for the E axis is
switched over to modulo display. The control automatically sets 0 in the case of 360°. The
programmed values are offset in modulo.
Effecl:
o Modal action
o Angle positions of the rotary axis or the angle of rotation are programmed in degrees
o G30 does notaffect positions of the linear axes (X, Y, Z)
o G30 does nol affecl zero shins (GS4 -G60, G160)
o Zero shifts are active; they are subjected to the Mmodulo 360- operation before execution.
o The rotary axis processes positive values .. The sign determines the direction of rotation.
o G3l resets G30 (consecutive degree display)
Programming:
G30 must be programmed separately in the Ne block. Ne addresses and other G functions are
not pennitted.

Coordinate rotation
G37 X_ Y _Z_A_
Definition:
A programmed contour is rotated by 8 specific angle about a defined canter of rotation.
The angle and canter of rotation must be defined in th~ part program.
Programminglcommand syntax:
Coordinate rotation is programmed with function G37, with the coordinate specification for the
canter of rotation (X, Y, Z) and the rotation angle (A). Other addresses are not pennitted.
Example: G37 X_ Y _A_
The canter of rotation is defined with two coordinates. Selection of the axes is dependent upon
the active working plane:
- if G17 is active, axis coordinates X and Y are selected
- if G18 is active, axis coordinates Z and X are selected
- if G19 is active, axis coordinates Yand Z are selected.
The axis entries are absolute values, referred to the active program datum.
G37 acts modelly.
G37. programmed without axis statements, resets active coordinate rotation.
Input range:
The rotation angle (A) is programmed with a value between -360' and 360'.
Negative angle entries define the coordinate rotation clockwise; apositive sign results in coordinate
rotation counterclockwise.
Interaction with other functions:
... Change of the group operating mode from AUTOMATIC to MACHINE or MACHINE to
AUTOMATIC resets G37.
... G37 is notpennitted in manual mode (group operating mode MACHINE). If a cycle in which
G37 is programmed is called in manual mode, this block is executed.
... The following functions reset G37: RESET, changing the working plane (G17, G18, G19),
switchover to polar coordinates (G20), G37 programmed separately, activate reference
pointapproach cycle (G74), G92 programmedseparately (reset to original machine coordina-
tes). G37 is not active after power-up of the control.
la" Coordinate rotation may not be programmed if radius compensation (G41. G42) is active.
G41/G42 with active G37 are permitted.
... The minimum and maximum values of the work area limits (G25, G26) may not be modified
when G37 is active.
