Card Cage Gain Setting Procedure
The motion control cards are pre-adjusted in the assembly area by commanding a move of 0.2048” and
adjusting the gain pot so the analog is
5
volts. This adjustment can be made on the machine as well, but
some parameters should be noted before making the adjustments.
Note 1:
Before making any adjustments on the Centurion 6 make sure that the AXIS parameters “Velocity
Gain” are set to zero and the machine is re-homed.
Note
2:
The offset pots should be adjusted to show zero following error when the machine is at rest
before making gain adjustments.
The gain adjustments done in the assembly area are done for moves on axes that have 10,000
pulses/inch. If the PPU on the machine is
something other than 10,000 you must move a different
distance. The 5 volts should be tuned in for a 2,048 pulse move.
Example 1:
A rotary axis has 500 pulses/degree. You should see 5 volts after a move of 4,096 degrees, (I.E.
10,000/500 x 0.2048)
Example 2:
A machine has a PPU of 10,160. You should see
5
volts after moving 0.2016 inches (I.E. 10,000/10,160
x 0.2048). In most cases this small difference is not significant.
Note
3: The encoder multiplier parameter will have no affect on the above adjustments.
