s word and actual speed on lathe spindle
« on: April 13, 2015, 07:22:08 AM »
Hello Chaps
Talking about speed and ratio on lathe spindle
My Machine has a gearbox with 12 gear ratios. I am using
an Omron drive controller

I have a 1400 motor and for this query I have selected
pulley number one and manually selected gear ratio that would give
spindle speed 80 rpm

When setting pulley ratio in the pulley ratio drop box
I have entered the following in the  .
pulley number 1
minimum speed 20
maximum speed 1400
ratio 1.01

With this setting when I say S1400 M4  then the speed actual reads 140 rpm and
a tachometer check on the spindle confirms that the spindle is actually
running at 140 rpm

While running as above the s word DRO is reading 1400 which confirms the speed that the
motor is running at.

this is means that the s word is referring to the motor speed.

I would have expected the s word to refer to spindle speed??

How do i get the s word to refer to spindle speed??

Regardfs
