TB011 Rev1 Parameter Setting for Rotary Tables
Steps
*Set the Machine Configuration as below for the 4th axis only
*DO NOT CHANGE THE VALUES FOR 1 2 3 AXIS!
1 For systems with an RTK2 PLC place jumpers on the RTK2 B H1 between pins 1 and 2 and pins 3 and 4
Go to the proper screens as follows F1 Setup F3 Config Password = 137 Enter ; then F3 Params or F2
Machine as instructed below Always be sure to use F10 Save before exiting
2 In the F2 Machine configuration set the #4 Axis label to W or a label that you prefer and edit this same line as
indicated below to replicate the proper configuration for the proper rotary table
NOTE The numbers in the HOME +/ field can vary from machine to machine Refer to the schematic for the machine
that you are working with for the proper input number
Parameters are as follows
Rotary Table Gear

Note The Max rate for the rotary tables is set by running F5 Tune from the PID menu start with fast jog value to run
autotune
3 To figure your Revs/degree you need to divide the Gear ratio by 360 See table above
4 In the F3 Params screen change parameter 94 to 1 0 this will flag that axis as rotary The conversational software
will then display degrees minutes and seconds for that axis in linear moves Also change parameter 98 to 45 0 the
autotune move distance
*To find feedrate for a rotary axis in degrees/min you must do the following
Surface Velocity/Part Diameter * 114 591559 = Deg/Min The Deg/Min is the input required for the feedrate
5 From the main screen of CNC10 press F6 Edit and open the file "c cnc10cnc10m hom" cnc10t hom for lathe
Add these lines at the end of the file for homing the rotary axis
If you have a home/limit switch add these lines
M92/W
M26/W
6 Some earlier Centroid Controls may require an updated RTK2 assembly if you find that H1 is not installed on the
circuit board and/or a PLC Program modification in order to use the "Clamp" feature Call Tech Support if this applies
*Special Note For Centroid Golden Sun with DC brush motor
The Kd parameter will need to be adjusted for the 17 lb motor that is installed in the table รข
Follow the instructions below
Go to the proper screens as follows F1 Setup F3 Config Password = 137 Enter ; then F4 PID F1 PID Use the
right arrow key to move over to the Kd column then the down arrow key to get to the correct row and axis in this case W
Change the value in this field to 5 000 Always be sure to use F10 Save before exiting
Testing
รขยข Check the clamp * With proper air supply press F3 MDI and then isue an M10 clamp on Verify that the table
is clamped or locked into position so that it cannot rotate Then issue an M11 clamp off to unclamp the table
รขยข Jog the 4th axis in both directions to verify proper motor wiring Note If the motor power leads are reversed an
axis will move the same direction a small amount no matter which jog key is pressed If this is the case call Tech
Support
รขยข Verify proper homing * During homing sequence the table will turn at the slow jog rate to the switch and then
come off the switch at 24 deg/min a short amount before setting home Note If the input is not connected the
table will turn at 24deg/min indefinitely
รขยข Go into MDI If the rotary table is labeled W enter the following commands W0 cycle start W360 cycle start
Verify that the table completes one revolution
รขยข If the table is the 4th axis set parameter 98 to 45 This will cause autotune to move 45 degrees on the rotary
table See chapter 10 in the manual Run Autotune
* Note Centroid RI 5C is not equipped with a clamp or home switch
Field upgrade checklist
รขยข A new PLC program for 4 axis system
รขยข A new wiring diagram
รขยข A 4th axis drive similar to the one in the machine i e is the 3 axis 12 12 15 brake? or a 12 12 12? etc
รขยข A new limit switch cable that goes from the PLC to the drive
รขยข A wiring harness for the inside of the Magnetics cabinet and tools to install the connector in the bottom of the
Magnetics cabinet If applicable
