B4: Timer Function - YASKAWA U1000 Series Technical Manual

 b4: Timer Function
The timer function is independent of drive operation and can be used to delay the switching of a digital output triggered
by a digital input signal. An on-delay and off-delay can be separately set. The delay timer can help to get rid of chattering
switch noise from sensors.
To enable the timer function, a multi-function input must be set to "Timer function input" (H1-=18) and a
multi-function output must be set to "Timer output" (H2-=12). Only one timer can be used.
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.

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.
demonstrates the timer function operation.

Note: Even if the length of the off-delay time and on-delay time for multi-function digital outputs are each less than 100 ms, the
multi-function digital output closes for at least 100 ms.
