*1 If the number of position/velocity pulses does not fit one word, set
the following bit to 1.

PLC0
2000
−
PLC0 (#0) Specifies whether to use the number of velocity or position pulses
without modifying them, as follows:
0: Not to modify
1: Multiply by 10 ← To be set
*2 Because the number of position pulses exceeds 130,000, specify
the position pulse conversion coefficient (supported by Series
90A0/N(14) and subsequent editions).
2628
−
Position pulse conversion coefficient (PSMPYL)
2185
−
Bit for multiplying the number of position/velocity pulses by ten
(PLC0) = 1
Number of pulses (PPLS) = 8000
Position pulse conversion coefficient (PSMPYL) = 2
Regard 160,000 pulses as: (8000*2)*10
*3-a Because the velocity loop proportional gain overflows, set the
following bit to 1 (supported by Series 90A0/I(09) and
subsequent editions).
