Spin up and down question

[andrew-h]

Hi.

In the spindle setup I asked for 5 seconds spin up and 20 secs spin down on a spindle that maxes at 14 000 rpm.

Does this mean that at 7000 rpm my values would be half of the requested values?

I have used a Delta VFD - an older EL series which responds very accurately to Masso's 10V signal. Additional to this I have programmed the VFD to have a minimum AVI signal (par 04.12) to limit the spindle to a minimum of 2000 rpm. All works perfectly except spin down and up have no bearing to the Masso formatted values.

Are the Delta Acc and Dec commands confusing the issue - parameters 01.09 and 01.10 - what must they be set at?

Thanks.

Andrew,

MASSOs spin up / down times are it's wait times before moving to the next Gcode command.

Arie.

OK - so a pre set delay to allow for a new S#### speed command to be in effect before moving on?

@andrew-h

Technically it's not related to the spindle RPM. Its merely a timer that pauses and waits for the countdown to complete before moving on. You have to test your machine to determine how much time your spindle will need.

Hope that helps!

Spindle Spin Up and Spin Down Enhancement Request

The Spindle Spin Up and Spin Down delays have become very important to us as we have recently implemented an Auto Tool Changer system. The Spin Down delay prevents a move-to, and engagement-of, the Tool Changer Rack before the tool has stopped spinning. This is all working very well, thanks to Masso.

But, there is still one concern, for which we will have to find a solution, or maybe Masso software update will help resolve.

With our new implemented Auto Tool Change system, manual Tool Change is still an occasional requirement, for this we have implemented a wired Push Button switch to the "Chuck Clamp Button" input pin, and when necessary it is used to: change, inspect, sharpen, etc. etc, to release the Tool Chuck. Thankfully, the Masso system does not allow the "Chuck Clamp Button" to be activated if the Spindle is in CW or CCW mode. BUT, our current Masso system does not respect the Spin Down Delay immediate after the Spindle is turn-off. A mis-pressed button could release a 30K rpm Tool onto table or into someones hand. Of course, we are skillful operators will try to avoid that kind of problem.

To help mitigate this problem (for our less skilled users), we plan to implement a lock-out for the "Chuck Clamp Button" line via a delay-relay triggered by the spindle CW/CCW enable line.

For the future, I would like to request a software enhancement that would deactivate the "Chuck Clamp Button" input-line during the configured Spin Down Time.



Thanks for your efforts
