Frequency Reference By Pulse Train Input - YASKAWA VS-606V7 Series Instruction Manual

Frequency Reference by Pulse Train Input

Frequency reference can be set by pulse train input from the control cir-
cuit terminals.
• Input pulse specifications
• Low-level voltage: 0.8 V or less
• High-level voltage: 3.5 to 13.2 V
• H duty: 30 to 70 %
• Pulse frequency: 0 to 33 kHz
• Frequency reference method
Frequency reference is a value obtained by multiplying the ratio of
the maximum input pulse frequency and actual input pulse fre-
quency by the maximum output frequency.

Run/stop and FWD/REV can be
selected by a switch connected
to the multi-function input.
[Set S1 and S2 to FWD run/stop
(n050 = 1) or REV run/stop (n051 = 2).]
Set the frequency by a pulse-train
input signal [0% to 100%
(maximum frequency)/0 kHz to 33 kHz]
from the control circuit terminal.
