b4-01, b4-02: Timer Function On-Delay, Off-Delay Time
b4-01 sets the on-delay time for switching the timer output. b4-02 sets the off-delay time for switching the timer output.


Timer Function Operation
When the timer function input closes for longer than the value set in b4-01, the timer output switches on. When the timer
function input is open for longer than the value set in b4-02, the timer output function switches off.

Multi-Function Digital
Outputs of H2-01
Note: Even if the length of the off-delay time and on-delay time for multi-function digital output are each less than 100 ms,
the multi-function digital output closes for at least 100 ms.
 b5: PID Control
The drive has a built in PID (Proportional + Integral + Derivative) controller that can be used for closed loop control of
system variables such as pressure, temperature, and so on. The difference between the target and the feedback value
(deviation) is fed into the PID controller. The PID controller adjusts the drive output frequency in order to minimize the
deviation, providing accurate control of system variables.

P Control
The output of P control is the product of the deviation and the P gain so that it follows the deviation directly and linearly.
With P control, only an offset between the target and feedback remains.
