4. 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
4.1 List of Related Devices
For details on related devices, refer to Section 4.2 to Section 4.4.
4.1.1 Special Auxiliary Relays
The following table shows the related special auxiliary relays. Note that Y000, Y001, Y002, and Y003 are
devices that determine the pulse output destinations.
For details on the PLSY (FNC 57), PWM (FNC 58), and PLSR (FNC 59) instructions, refer to the
programming manual.
