2) Deviated traverse X, Y operation
The deviated traverse operation shown below takes place with the sequence commands
S0 (X) and S1 (Y) during traverse operation.
X (B45-5)
Y (B45-6)
FH (B45-0)
S0(X)
Center frequency (Speed)
S1(Y)
0
Deviated traverse X, Y operation
The center frequency (speed) rises by X (B45-5) only while S0 (X) is ON.
The center frequency (speed) lowers by X (B45-6) only while S1 (Y) is ON.
3) Changing the center frequency (speed) with settings from an external source
While the PROG command is ON and the traverse operation is taking place, when the
sequence commands S0 and S1 both turn ON, the center frequency value (speed) value
will be the value set from an external source selected with C07-4.
If both S0 and S1 are turned ON, the center frequency (speed) will be the value set from
the external terminal. However, the frequency will first return to the center frequency
(speed) before rising or lowering to the newly set value. After that, the same operation will
take place even when the setting value is changed from an external source.
4) Precautions for application
(1) If the parameter No. B45-0 to 6 setting data is changed during traverse operation, the
output frequency (speed) will return to the center frequency (speed) once.
Then, traverse operation based on the newly set data will take place.
When returning to the center frequency (speed), the output frequency (speed) will
change at the cushion (A01-0, 1)
(2) The overcurrent limit (OCL) and overvoltage limit (OVL) functions will not activate
during traverse operation, so carefully consider the inverter capacity, motor capacity
and traverse related setting values when designing the system.
(3) The output frequency (speed) is limited between 5.00 and 100.00% during traverse
operation.
(4) When carrying out deviated traverse, take care not to turn the S0(X) and S1(Y)
commands ON simultaneously.
If turned ON simultaneously, the (3) center frequency (speed) will change.
