14=”AI1/AI2 Sel” – AI1/AI2 Selection
Digital Input “I/O Ref 1/2” is used to select between Analog Input 1 and Analog
Input 2 reference. “I/O Ref 1/2” is sued to elect between “I/O Reference” and “I/O
Reference 2” if selection is different than 14 (this one).
15=”Encoder 1”
Reference is read from encoder input 1.
16=”Encoder 2”
Reference is read from encoder input 2. This selection is usable with double
encoder boards. Could be used e.g. for speed synchronization where two motor
needs to run at same speed but not necessarily same angle.
17=”PID Output”
Reference is read from the output of the PID controller see group P1.17 for PID
controller settings
P1.2.5
1241
Speed share “speed share”
Defines the speed reference percentage ratio after final reference location but before
ramp control. Monitoring value “FreqReference” shows the reference after speed
share function. Used to adjust reference ration e.g. in line drive that PLC can give same
reference to all drives while speed share compensate gear ratio affect to the line
speed.
P1.2.6
1248
Load share “load share”
Defines the percentage for final torque reference after final torque reference location
selection but before the torque reference step function, torque reference dead zone
and reference filtering.

Jogging speed reference “jog speed ref”
Defines the jogging speed reference when activated by a digital input. This reference
will follow the reverse command if given. Jogging speed has a higher priority than
preset speed references.
