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.

Run/stop and FWD/REV can
be selected by a switch
connected to the control circuit
terminal.
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.
