parameter setting

[caddisfly]

I have a Haas VF-6 WITH A HR450 Indexer. A very heavy chuck has been
installed onto the indexer.
I would like to limit the indexer rapid feed rate. Is there a parameter
that can be set to limit the feed rate for the indexer rapids? A(AXIS)

thanks

Parameter 49 is A Acceleration, Parameter 50 is A maximum Speed.

It may be a good idea to lower the acceleration as well as the speed. I had a tool turret with some long heavy tools and found just lowering the speed was not enough, I had to lower the acceleration to avoid getting tool change alarms.

I will give that a try.

Geof,

What unit value do those to parameter settings represent?
And are there any other A axis parameter settings that could be adjusted ?

I also would like to do the same with the x and y axis.

What parmeters would control them?

Setting 34 in the Haas control will slow the fourth axis down depending on the part diameter. You have a range of 0 – 29.9”.

If you tried setting 34 and it still feeds too fast for your application then you can lower the acceleration.

Only adjust parameter 49 - Acceleration to a lower number. These are steps per second of the motor.



Please keep in mind that if you are contouring a part on the A-axis. The finish may be affected because by lowering the A-Axis acceleration you are now disturbing the synchronization of the axis.

If it’s just to position the 4th axis at a slower rate then it will be okay to lower the acceleration without a problem.

Parameter 7 is X acceleration, 8 X max speed, 21 Y accel., 22 Y max speed, 35 Z accel., 36 Z max speed.
