4.8.2.3 CODE 134: Friction Feed Forward Constant
This is a tuning parameter for adjusting the machine’s friction characteristics. It is set at the factory
by
running a ballbar plot using a measurement probe device, such as one made by Renishaw, and adjusted
to obtain minimal error. It is not recommended to change the values unless told to do so by a service
representative.
4.8.2.4 Code 400: Update Foreign Language MLS Files
If you have received a foreign language update for your machine, you can put it on a USB flash drive,
and enter this service code to update your control.
4.8.2.5 Code 501: Set Z Tool Change Height
Sets the location, relative to home, where the Z axis will change its tools for the Automatic Tool Changer.
This will need to be set if the Z motor or Z ballscrew is ever replaced. Major changes to the Z limit
switches or limit switch cams may also require this. See service code screen for instructions.
4.8.2.6 Code 505: Over Travel Limits
When entering this service code, both the soft limits will be disabled so as to allow for setup or
troubleshooting. If a soft limit is triggered, it will stop the motor from moving any further, but will not
fault out or kill power to the motor.
In addition to the DRO, the motor index angle for each axis relative to the limit switch can be seen. This
is to ensure that the index pulse for the motor is close to 180 degrees when it hits the limit switch. This
is done to obtain maximum reliability when the machine performs its homing routine. The angle should
be 180 d/- 45 degrees. Values from 135 to 225 degrees are acceptable. Failure to set this
correctly may cause the machine to not home properly which can lead to major problems.
1.
SOFT LIMIT ON / OFF
–
You can choose to toggle the soft limits on or off. They will default to
off when entering this service code, but will always turn back on after exiting.
2.
In order to find the index angle, you manually select the desired axis and then carefully move it
using the handwheel. When the home switch banner lights up on the screen you are able to
view the index angle.
4.8.2.17 Code 510: Electronic Spindle Setup
Use these service codes to setup or troubleshoot the electronic spindle.
1.
CAL RPM
–
Running this routine will automatically calibrate the spindle over several increments from
its minimum to maximum rated speed. The process should take between 1-2 minutes to complete.
2.
ORIENT SPINDLE
–
This sets the orientation of the spindle in relation to the ATC when the
machine performs a tool change. Follow the instructions on screen to set or verify the orientation of
the spindle.
a) ATC IN
–
brings the ATC in towards the spindle. Make sure the Z axis is high enough to clear
the ATC before using.
b) ATC OUT
–
moves the ATC back out and away from the spindle.
