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 multi-function input
terminal.
• Input pulse specifications
• Low-level voltage: 0.8V or less
• High-level voltage: 3.5 to 32V
• 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 frequency by the
maximum output frequency.

Frequency setting can be set
by pulse train input signal [0 to
100% (maximum frequency)/
0 to 33kHz] connected to the
multi-function input terminal.
