Pulse Outputs

Accelerating the Frequency at a Fixed Rate

Note
In this example, the SPED(885) instruction is used to change the speed of a
pulse output from port 2 from a frequency of 3,000 Hz to 50,000 Hz. In this
case, the pulse output is a CCW continuous mode output.
Speed control timing will be accurate when frequency changes are executed
by SPED(885) instructions in interrupt tasks called by input interrupts.
In this example, the ACC(888) instruction is used to accelerate the pulse out-
put from port 2 from a frequency of 3,000 Hz to 50,000 Hz at an acceleration
rate of 500 Hz/2 ms.

Target frequency
When CIO 0002.00 turns ON,
SPED starts a pulse output from
port 2 at 3,000 Hz (3 kHz) in
CCW continuous mode.
When CIO 0002.01 turns ON,
SPED changes the frequency
to 50,000 Hz (50 kHz) in CCW
continuous mode.
When CIO 0002.00 turns ON,
SPED starts a pulse output from
port 2 at 3,000 Hz (3 kHz) in
CCW continuous mode.
When CIO 0002.01 turns ON, ACC is
executed in mode 1 (CCW direction,
acceleration, and continuous mode) to
accelerate the frequency at 500 Hz/2 ms
to 50,000 Hz (50 kHz).
