6. Output pulse frequency
Specifies the frequency of the pulses to output.
The frequency is specified between 15 Hz and 5 kHz in 1 Hz increments.
The pulse frequency error is within ±5%.
7. Pulse width ratio
This setting specifies the ON ratio (duty cycle) for the pulse frequency to output.
If the configuration mode is FC6A Standard Mode, the pulse width ratio is specified between 0.1% and 100.0% in 0.1%
increments. If the configuration mode is FC4A Compatible Mode, FC5A (except FC5A-D12X1E) Compatible Mode, or
FC5A-D12X1E Compatible Mode, the pulse width ratio is specified between 1% and 100% in 1% increments.
8. Pulse counting
Enables or disables pulse counting.
If Enable pulse counting is specified, the number of pulses specified by the preset value (9) is output.
If Disable pulse counting is specified, pulses are continuously output while the PULS instruction input is on.
9. Preset value
When the setting for 8. Pulse counting is Enable pulse counting, this setting specifies the number of pulses to output.
10. Current value
Specifies the device (data register) that will store the number of pulses that were output.
The current value is updated when the PWM instruction is executed at each scan.
11. Error status
Outputs the error code that corresponds to the content of an error when there is an error in the settings. If a configuration error
occurs when the PWM instruction input changes from off to on, a user program execution error will occur and error code 20 will
be stored in D8006.
Error Code Status Description
0Normal —
1 Output frequency designation error The pulse frequency was not set between 15 and 5,000.
2 Pulse width ratio designation error The pulse width ratio was not set between 1 and 1,000.
4 Preset value designation error
If Enable pulse counting is specified, the preset value was not set between
1 and 100,000,000.
