Outline of operation
• Outputs pulses from a specified channel when a corresponding control active flag is OFF
and the execution condition is ON.
• The control code, initial speed, maximum speed, acceleration/deceleration time, and target
value are specified by creating data tables [S] to [S+11] described on the next page using a
user program.
• Switches the frequency from the initial speed to the maximum speed in the specified
acceleration/deceleration time. At the time of deceleration, switches the frequency with the
same inclination as that for acceleration.
• For setting the frequency to 50 kHz or more, specify the duty of 1/4 (25%).
