- Sample program
Sample 1 : Program to turn terminals Y (00) to Y (05) on sequentially while the output frequency is increased in 10-Hz steps.
(The inverter operation is the same as that programmed in sample 2.)

: Set the output frequency to 60 Hz.
: Set the acceleration time to 30 seconds.
: Set the deceleration time to 30 seconds.
: Start forward rotation of the motor.
: When the output frequency is less than 10 Hz,
: turn Y (00) on.
: When the output frequency is less than 20 Hz,
: turn Y (01) on.
: When the output frequency is less than 30 Hz,
: turn Y (02) on.
: When the output frequency is less than 40 Hz,
: turn Y (03) on.
: When the output frequency is less than 50 Hz,
: turn Y (04) on.
: When the output frequency is less than 60 Hz,
: turn Y (05) on.
: Decelerate and stop the motor.
