number increments master x x
The inverse direction of rotation of the slave to the master drive is reached by a negative value for
Ec.14.
Example(adjustmentsforgure7.12.3.3positionnormalization):
"Normal" speed-controlled operation is programmed in the master, the synchronous module is not activated.
For the slave, encoder channel 1 serves as speed feedback and encoder channel 2 as master position infor-
mation. Both loads shall be moved angular-synchronous, but in opposite direction of rotation.
Adjustment in the slave:
- PS.00 "Posi / synchronous mode" = synchronous mode
- CS.01 "Actual source" = channel 1
- PS.01 „Actual position source“ = channel 2
- PS.06 "KP for positioning / synchronous" ≠ 0
- EC.14 "Gear 2 numerator" = -1500
- EC.15 "Gear 2 denominator" = 525
Typically, an approach to reference point is executed for the slave drive before starting synchronous running,
in order to get the reference between position display of the slave drive and the mechanics of the application.
The reference between master and slave position is done only with activation of the synchronous module.
During activation the master position (= ru.56 "set position") is set equal to the slave position (= ru.54 "actual
position").
7.12.3.4 Synchronous mode / selection of operating mode
The operating mode synchronous mode is selected via parameters PS.00 bit 0...3 or via the control word (Sy.43
or Sy.50)
PS.00: Posi / synchronous mode
Bit Meaning Value Explanation
0..3
Posi-/synchro-
nous mode
0: off no special operation selected
1: Synchronous
mode
Selection of operating mode "synchronous mode"
2...6 Without function for synchronous mode
7: via control word
The operating modes (synchronous running, positioning mode
or contouring control) are selected via the control word (Sy.43
or Sy.50).
If PS.00 bit 0...3 contains the value 7:
