Pr44 Numerator of Feedback Pulse Frequency Multiplication
Range: [1, 32767]
Example: when pulse equivalent is 0.001, pitch 10mm, without reducer, set this
parameter to 2500; when pitch 5mm, set it to 1250.
Set value: set it according to PG divider ratio (Weihong system).
Pr48 1st Numerator of Command Pulse Frequency Multiplication, Pr4B
Denominator of Command Pulse Frequency Multiplication
Range: [1, 10000]
Example: pitch 5mm, encoder resolution 10000, shaft coupling direct drag, pulse
equivalent 0.001mm: Pr48=10000, Pr4B=pitch 5mm / pulse equivalent
0.001mm=5000, thus, Pr48/Pr4B=10000/5000=2/1.
Set value: to be calculated.
Panasonic MINAS A5 Servo Drive
Pr5.28 LED Initial Status
Monitor if the number of sent and received pulse is correct by setting this
parameter.
In Weihong control system, the correct quantity of pulse sent by control card is
detected by pulse inspection to determine whether there is electrical interference.
Set value: 6
