Description
The encoder simulation is a mirror of the actual position. The
output is scaled by parameter 5-75 Term 27/29 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 represented by the number of pulses set in parameter 5-75
Term 27/29 Pulses Per Revolution.
The encoder simulation is a mirror of the commanded position
(position setpoint for the position PI controller). The output
is scaled by parameter 5-75 Term 27/29 Pulses Per Revolution
related to 1 motor revolution. This means that 1 motor revolution
is represented by the number of pulses set in parameter 5-75
Term 27/29 Pulses Per Revolution.
The encoder simulation is generated by the virtual master
function. The output is scaled by parameter 5-75 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 x 60/min x 50% =1500 RPM. The
pulse frequency will be parameter 5-75 Term 27/29 Pulses Per
Revolution, for example, 1024 x 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 Denominator, parameter 17-72 Position Unit Numerator,
and parameter 17-73 Position Unit Denominator.
The encoder simulation is a mirror of the encoder signal on
terminal 32/33. The drive can be used as repeater.
