When, in final operation, we do not use one of the Index operation modes, we can exit the Test
Menu now. Where Index functions will be needed later, click to the ”Master Index” and the
”Slave Index” boxes to execute the following tests:
•
When you move the corresponding axis forward, you will find the number of encoder
pulses between two index pulses in the display window. Where the index comes from
the encoder itself, this is the ppr number of the encoder. Many times, when using
external index pulses from a proximity, the accurate number of pulses between two
markers is not exactly known and you can find it out by this test (see ”N”, ”K” and
”Factor1” in section 6. which is important for successful index operation!).
•
When we move slowly enough, we can also see the index pulses blinking in one of the
indicator boxes (Upper = HTL-index, Lower = TTL-index).
•
When we rotate to reverse direction, the display will not show our impulse number, but
its 16 bit complement which is ”65536 - impulse number”.
After performing the index tests, exit the test menu and get back to the main screen.
We must now adjust our Gain Total setting. This is to ensure the Slave drive receives the
correct speed reference voltage for the speeds it should run.
Select the Adjust function of the Tools menu.
The subsequent procedure assumes our Gain Correction is set to 100 and you do not touch Gain
correction before we have set Gain Total.
