Tab. 6-176: resistance values for p ull up and pull down resistances
Stray capacitances of the wiring greately differ according to the cable type and cable laying, the
above cable length is not a guaranteed value.
When using a pull up resistance, check the permissible power of the resistor and permissible
load current of output transistor and use them within a permissible range.
NOTES
When pulse train input is selected, a function assigned to terminal JOG using Pr. 185 JOG
terminal function selection is made invalid.
When Pr. 419 Position command source selection = "2" (conditional position pulse train
command by inverter pulse train input), JOG terminal serves as conditional position pulse
train terminal regardless of the Pr. 291.

Tab. 6-177: Pulse train input specification
The wiring length of complementary output depends on the output wiring specifications of
complementary output device. Stray capacitances of the wiring greatly differ according to
the cable type and cable laying, the maximum cable length is not a guaranteed value.
NOTE
When pulse train input is selected, a function assigned to terminal JOG using Pr. 185 "JOG
terminal function selection" is made invalid.
