b4: Timer Function
The timer function is independent of drive operation and can delay the switching of a digital output triggered by a digital input
signal and help eliminate chattering switch noise from sensors. An on-delay and off-delay can be set separately.
To enable the timer function, set a multi-function input to “Timer Function Input” (H1-oo = 18) and set a multi-function
output to “Timer output” (H2-oo = 12). Only one timer can be used.
n
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.
No. Name Setting Range Default
b4-01 Timer Function On-Delay Time 0.0 to 3000.0 s 0.0 s
b4-02 Timer Function Off-Delay Time 0.0 to 3000.0 s 0.0 s

Timer Function Operation
The
timer function
switches on when the timer function input closes for longer than the value set to b4-01. The timer function
switches off when the timer function input is open for longer than the value set to b4-02. Figure 5.22 illustrates the timer
function operation:

Time period that the multi- function
digital output is closed 100 ms
Time period that the multi-function
digital output is closed < 100 ms
Time period that the multi-function
digital output is closed = 100 ms
Note: The multi-function digital
output closes for at least 100 ms even when the length of the off-delay time and on-delay time for multi-function
digital output are each shorter than 100 ms,
