Using The Timer Function - YASKAWA Varispeed F7 Instruction Manual

Using the Timer Function

Multi-function contact input terminals S3 to S8 can be designated as timer function input terminals, and multi-
function output terminals M1-M2, P1-PC, and P2-PC can be designated as timer function output terminals. By
setting the delay time, you can erase chattering from the sensors and switches.
Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8) to 18 (timer func-
•
tion input).
Set H2-01 to H2-03 (multi-function output terminals M1-M2, P1-PC, and P2-PC function selection) to 12
•
(timer function output).

Setting Example
When the timer function input ON time is longer than the value set in b4-01, the timer output function is
turned ON. When the timer function input OFF time is longer than the value set in b4-02, the timer output
function is turned OFF. An example of timer function operation is given in the following diagram.
