Select the source for generation of the encoder simulation output. To enable 24 V encoder simulation on terminal 27/29, set param-
eter 5-30 Terminal 27 Digital Output and parameter 5-31 Terminal 29 Digital Output to [54] 24V Encoder Sim.
Op- Name Description

[1]* Actual po-
The encoder simulation is a mirror of the actual position. The output is scaled by parameter 5-75 Term 27/29
sition
Pulses Per Revolution related to 1 motor revolution. One motor revolution is represented by the number of
pulses set in parameter 5-75 Term 27/29 Pulses Per Revolution. This means that 1 motor revolution is repre-
sented by the number of pulses set in parameter 5-75 Term 27/29 Pulses Per Revolution.
[2] Comman- The encoder simulation is a mirror of the commanded position (position setpoint for the position PI control-
ded posi-
ler). The output is scaled by parameter 5-75 Term 27/29 Pulses Per Revolution related to 1 motor revolution.

[3] Vir. master The encoder simulation is generated by the virtual master function. The output is scaled by parameter 5-75
position
Term 27/29 Pulses Per Revolution. Virtual master speed reference can be set by fieldbus REF 1 or the source
selected in parameter 3-16 Reference Resource 2 relative to parameter 3-27 Virtual Master Max Ref. Example:
With parameter 3-27 Virtual Master Max Ref = 50 Hz and a reference of 50% the output corresponds to a
master speed of 50 Hz * 60/min * 50% =1500 RPM. The pulse frequency will be parameter 5-75 Term 27/29
Pulses Per Revolution, for example, 1024 * 1500 RPM / 60 = 25.6 kHz. Speed of the individual followers is
determined by their scaling in parameter 3-22 Master Scale Numerator, parameter 3-23 Master Scale Denomi-
nator, parameter 17-72 Position Unit Numerator, and parameter 17-73 Position Unit Denominator.
[4] 24V en- The encoder simulation is a mirror of the encoder signal on terminal 32/33. The drive can be used as repeat-
coder er.
