Frequency Detection
Multi-function terminal function selection
H2-01 to 03
Frequency detection level L4-01，L4-03
Frequency detection width L4-02，L4-04
Various frequencies can be detected by setting the
following values in terminal M1-M2, P1 and P2 function
selection (H2-01, 02 and 03).
As shown above, select the detection with or without sign in
the Varispeed G7.
The following is the frequency (speed) agree timing chart. The
figure shows the case of forward rotation; the direction for
reverse rotation without sign is the same. When detection with
sign is selected, detection signal against the specified direction
of rotation is detected according to the direction of rotation.
