 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.

Reference frequency =

Maximum pulse train frequency (n149) × 10

× Maximum output frequency (n011)
