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
• Duty Cycle: 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.
