Function
l
After mains connection and simultaneous HIGH level at both inputs, the outputs are
connected as follows:
Inputs Outputs
R/L/Q-R R/L/Q-L R/L/Q-R/L R/L/Q-QSP
1 1 0 1
l
The following table results, only if one of the inputs was set to LOW once:
Inputs Outputs
R/L/Q-R R/L/Q-L R/L/Q-R/L R/L/Q-QSP
0 0 0 1
1 0 1 0
0 1 1 0
1 1 unchanged unchanged
l
If both inputs are set to HIGH during operation, both outputs still have their previously output
value.
7.6.64 Homing function (REFC)
One function block (REFC1)is available.
Purpose
The homing function is used to bring the drive shaft to a certain position.
Note!
First, select a defined configuration under C0005, which already includes the function block REFC.
This ensures that all important signals are connected automatically. Then adapt the configuration to
your application.
