◆ b4: Delay Timers

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 input" (H1-=18) and a multi-function
output must be set to "Timer output" (H2-=12). One timer can be used only.
■
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.
