· Setting any of "1, 11, 21, 100" in Pr. 291 Pulse train input selection and a value other than "0" in Pr. 384 Input pulse
division scaling factor switches terminal JOG to pulse train input terminal and frequency setting of the inverter can be
performed. (The initial value is JOG signal)
Pulse train input of maximum of 100k pulse/s is enabled.
· Output specifications (high speed pulse train output or FM output) of terminal FM can be selected using Pr. 291.

Indicates division scaling factor to the input pulse and the
frequency resolution to the input pulse changes according
to the value.
Set the frequency when the input pulse is 0 (bias).
Set the frequency when the input pulse is maximum
(gain).
