Sample 2: Program to output codes sequentially to terminal Yw while the output frequency is
increased in 10-Hz steps. (The inverter operation is the same as that programmed in
sample 1.)

entry
SET-Freq= 6000 : Set the output frequency to 60 Hz.
ACCEL= 3000 : Set the acceleration time to 30
seconds.
DECEL= 3000 : Set the deceleration time to 30
seconds.
Yw= 0
FW= 1 : Start forward rotation of the motor.
LOOP if FM < U(00) then LBL1 : When the output frequency is less than
10 Hz
