6. Control Functions and Parameter Settings6-532) Deviated traverse X, Y operationThe deviated traverse operation shown below takes place with the sequence commandsS0 (X) and S1 (Y) during traverse operation.X (B 45 -5 )Y (B 45 -6 )F H (B 4 5-0 )S 0 (X ) C e nte r freq ue nc y (S p ee d)S 1 (Y )0Deviated traverse X, Y operationThe 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 sourceWhile the PROG command is ON and the traverse operation is taking place, when thesequence commands S0 and S1 both turn ON, the center frequency value (speed) valuewill 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 fromthe 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 willtake 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, theoutput 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) willchange at the cushion (A01-0, 1)(2) The overcurrent limit (OCL) and overvoltage limit (OVL) functions will not activateduring traverse operation, so carefully consider the inverter capacity, motor capacityand traverse related setting values when designing the system.(3) The output frequency (speed) is limited between 5.00 and 100.00% during traverseoperation.(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.
