No.
Action
1
Open manual mode window.
2
Approach start position
3
Speed control mode control setting (set high rigidity, for smooth running)
4
Set the teaching direction if necessary:
P 445[0] - CON_TAB_TeachDir
Default: POS(1)= teaching routine in positive direction.
5
Set the offset and delta if necessary using:
P 442[0] - CON_TAB_PosStart
, default 0
P 443[0] - CON_TAB_PosDelta
, default 1000 inc/TabElement
= e.g. (endpos inc - startpos inc) / 4000 elements
6
Set the input tuning if necessary using:
P 447[0] - CON_TAB_Tune.TimeDelay
, default 0
P 447[1] - CON_TAB_Tune.PosShift
, default 0
7
Start control
8
Run motor at low speed (≤ 1 rpm).
9
Set the position source for the teaching, activate teaching: Select
P 385[0] - CON_TCoggTeachCon= (5)TeachUserRefPos
or select
P 385[0] - CON_TCoggTeachCon= (7)TeachPosEncPcon
or select
P 385[0] - CON_TCoggTeachCon= (9)TeachPconActPos
or select
P 385[0] - CON_TCoggTeachCon= (10)TeachPosEncRed
.
à
The teaching routine begins (but only with PosStart).
10
Wait until at least 1 motor revolution is completed in the teaching routine
(internal filter time).
---
Check
P 440[0] - CON_TAB_TabIndex
and
P 446[0] - CON_TAB_OutVal
11
With the control still operating, the teaching is then stopped by calling the
calculation function once.
P 385[0] - CON_TCoggTeachCon = (3)CALC1.
This imports all values into the internal compensation table (big table with
4000 elements).
