Setup Of Motor Rotational Speed And Input Pulse Frequency - Panasonic MINAS A6 Series Operating Instructions Manual

Setup
Input pulse frequency
Note
When setting Pr0.08, and encoder resolution is automatically set up as numerators. For
full closed controlling, setting of Pr0.08 is ignored and settings of Pr0.09 and Pr0.10 are
always applied.
Caution
• Max. input pulse frequency varies depending on input terminals.
• The desired setting can be determined by selecting value of numerator and denomina-
tor of electronic gear. However, an excessively high division or multiplication ratio can-
not guarantee the operation. The ratio should be in a range between 1/1000 and 8000.
Excessively high multiplication ratio will cause Err27.2 (command pulse multiplication
error protection) due to varying command pulse input or noises, even if the other set-
tings are within the specified range.
Relation between the motor
rotational speed and input
pulse counts
When setting the command division and multiplication ratio
as numerator/denominator, express it as Pr0.09/Pr0.10 with
Pr0.08 = 0. For full closed controlling, setting of Pr0.08 is ig-
nored and settings of Pr0.09 and Pr0.10 are always applied.
e.g.) When you want to rotate the motor by 60° with the load
