Target frequency
When start input CIO 1.04 turns ON, 600,000 pulses are output internally for
inverter positioning 0 to turn the motor shaft.
Refer to 7-3-7 Determining the Internal Pulse Output Frequency for the for-
mula to convert the frequency and use the converted internal pulse frequency.
The number of output pulses is calculated from the encoder specifications
and the high-speed counter multiplier.
