Using The Timer Function - YASKAWA Varispeed G7 Instruction Manual

Using the Timer Function

Multi-function contact input terminals S3 to S12 can be designated as timer function input terminals, and
multi-function output terminals M1-M2, P1-PC, P2-PC, P3-C3, and P4-C4 can be designated as timer func-
tion output terminals. By setting the delay time, you can erase chattering from the sensors and switches.
Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12) to 18 (timer
•
function input).
Set H2-01 to H2-03 (multi-function output terminals M1-M2, P1-PC, P2-PC, P3-C3, and P4-C4 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.
