5.4.2.5 Parameter Setting of Panasonic MINAS A5 Servo Driver
Monitor if the number of sent and received pulses is
correct by setting this parameter. In Weihong control
system, the correct quantity of pulses sent by control
card is detected by pulse inspection in order to determine
whether there is electrical interference.

0: Photo-coupler input (PULS1, PULS2, SIGN1, SIGN2)
1: Exclusive input for line driver (PULSH1, PULSH2,

Typical value: pitch 5 mm, encoder resolution 10000,
deceleration ratio 1:1, pulse equivalent 0.001 mm:
Pr0.09＝10000
Pr0.10＝pitch 5mm/ pulse equivalent 0.001mm＝5000
Pr0.09/Pr0.10=10000/5000=2/1

Range: 1~262144, set according to the parameter setting
of ―Frequency Division Pulses of PG (X4)‖.
Typical value: pulse equivalent 0.001, screw pitch 10mm
without a reduction box, Pr0.11=2500; screw pitch 5mm,
Pr0.11=1250.
When the value of Pr0.08 is not ―0‖, it can be calculated in terms of the following formula:
Screw pitch 5mm
Command pulse No. per motor circle 5000
Pulse equivalent Mechanical deceleration ratio 0.001mm/ p
When screw pitch is 5mm and pulse equivalent 0.001, the value of Pr0.08 is ―5000‖.
