Set value error code
Automatically writes an error code (11 to 17) into DM9407 when a parameter setting
error is found at startup.

Corrective action for error code 16
Error code 16 is issued when the output pulse count during acceleration/decelera-
tion time exceeds other values calculated from the preset parameters.
To recover from the error, the following corrective actions are available.

Change the run frequency and/ or the acceleration/ deceleration time according
to the following expression.

Corrective action for error code FFFF (-1)

Reduce run frequency and start frequency.

Reduce accelleration/ deccelleration time.

Start frequency (Hz)
Sets a start frequency (speed) to start the motor rotation smoothly during positioning
control.

The KV-300 CPU outputs clock pulses at the specified frequency.

Run frequency (Hz)
Sets the motor frequency (speed) during positioning control. The KV-300 CPU
outputs clock pulses at the specified frequency.

Note: When the start frequency equals the run frequency, the system operates as
shown in the following chart.

Here, the acceleration/deceleration time is ignored. The output count should be less
than 65535.
