Test the Zero pulses of the incemental encoder system over the whole travel range ’reference

error’ 20

After activating the reference error menu the position counter is permanently active so the manu-

ally moved distance will be counted to. The Zero pulses are only counted at the automatic posi-

tioning to back to the programmed position (Zeropoint count between Start and End signal).

The count pulses before the first Zero pulse and after the last Zeropulse are counted and titled as

’Error per Zeropulse’.

These are not count errors.

Alternatively to the manuell movement of the axis and the automatic scrolling back for the mea-

surement you can also run a continous run for a Tracksignal and zero pulse check. Therefore run

a positioning over the full travel range with more then 2 seconds waiting time at each position. So

you are able to ’start for measurement’ at one position and stop the measurement at the other po-

sition. After stop the result is displayed. If you run continus run for multiple distances the Zero

pulse counter count on; the position counter count positive and negative according the moving di-

rection.

axis can be shown

nection’ menu.

20.3.3 Assessing the Axis Dynamic Signal (also for ’Beginner’Mode)

The SIPLACE Axis Tester uses the (signal) option 1 menu as a default for displaying axis dynamic

signals. To reconfigure this setting please refer to Fig. 20.3 - 1, Chapter 20.3.2.1.

Adjusting the

tacho: The ta-

cho signal is di-

rectly

connected

from the servo/

adjustment

board pins to

the oscillo-

scope input.

Assessing the

positioning

quality:

Measuring the

traversing

time/over-

shoots.

Fig. 20.3 - 6 SAT’ operating sequence

The sequence of steps for setting the axis dynamic depends on the operating sequence and con-

nection descriptions for the relevant machine type.

20.3.3.1 Default Terminal Assignment of SAT BNC Outputs for Assessment of Dynamics

– V

nom

. is emitted at the SAT BNC output 1.

– SAT BNC output 2 supplies the nominal current for an AC axis with

Vreg (uncommuted current

signal). However, this is only connected for AC star axes with full digital control. The oscillo-

scope input CH3 can be used for this

Vreg signal. For both DC (Z, DP) and "analog AC"(X,Y)

axes CH3 is free for

actual

servo current signals.

–A

nom

signal (force output at axis controller/at the axis test box) is provided at BNC output 3.

This is the additional acceleration signal for the gantry axes or the force limitation signal for the

Z-axis.

– A connection for the

end signal is provided at SAT BNC output 4. This signal is generally used

as a trigger signal (exeption Z-Axes).

Appendix

– The deviation of position signal of the respective Axes are (without any further action) dis-

played and analysed on the SAT LCD-Display.

The

Positioning time is the ’whole travel time of a positioning’ (Start signal to End signal).

The

Control time is the time from start to the first arrival at the target position.

The

Pull off Time is the time to control the generated overshoots down to limits.

Positioning time = Control time + Pull OFF time

– With ’Return’ <

, ’Oscilloscope-Mode’, and ’Signal line (2 or) 3’ we connect the deviation of

position signal of the respective Axis to the SAT BNC output. We can measure with the free

Osci-input CH2 (CH3) the deviation of position signal synchronous to the other dynamic sig-

nals.

20.3.3.2 SIPLACE Axis Tester ’SAT’ Display

The diagram in the SAT display

shows a typical overshoot (as in

Fig. 20.3 - 7 at the top) and the

corresponding analysis

times.The delays between posi-

tionings should be set long

enough to allow the values to be

read and assessed.

Confirm with <

and select ’PWM

mode’ and ’dynamic’ to display

the position deviation signal on

the oscilloscope. If no overshoot

occurs during the positioning pro-

cess (see Fig. 20.3 - 7 at the bot-

tom) (asymptotic approach), the

positioning time (pos) and the

control time (CTRL) will be

switched simultaneously. There

is therefore no

’pull off time’

(pull off)

during which the over-

shoot is corrected.

PLEASE NOTE:

The display is automatically

scaled to the overshoot size and

time!
