Setting the Timer Function (b4)
The timer function is enabled when the timer function input (set value: 18) and the timer function output
(set value: 12) are set for the multi-function input and multi-function output respectively. These inputs
and outputs serve as general-purpose I/O. Chattering of sensors, switches, and so on, can be pre-
vented by setting a delay time.

These parameters cannot be changed during operation.
•
When the timer function input ON time is longer than the value set for b4-01 (timer function ON-delay
time), the timer function output turns ON.
•
When the timer function input OFF time is longer than the value set for b4-02 (timer function OFF-
delay time), the timer function output turns OFF.

Setting PID Control (b5)
The PID control function is a control system that matches a feedback value (i.e., a de-
tected value) to the set target value. Combining proportional (P), integral (I), and deriva-
tive (D) control makes control possible even for a mechanical system with dead time.
The PID control provided by the SYSDRIVE 3G3FV Inverter is not suited for control that
requires a responsiveness of 50 ms or less.
This section explains the PID control applications and operations, along with the param-
eter settings and tuning procedure.
