B4: Delay Timers - YASKAWA FSDrive-MV1000 Parameter Manual

◆ b4: Delay Timers

The timer function is independent of drive operation and can be used to delay the switching of a contact output triggered
by a contact 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 contact input must be set to "Timer input" (H1-
to "Timer output" (H2-

Parameter b4-01 sets the on-delay time for switching the timer output. Parameter 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. The following
diagram demonstrates the timer function operation.
