Before Programming

This chapter describes several items that should be known before programming. They are:
• Operation of related devices, such as output pulse frequency, operation command flag, current value, and
operation monitor flag.
• Items to be set on the PLC side
• Items to be set on the servo amplifier (drive unit) side
• Items to be observed in programming
