Set PWM #0

\i I P long::freq word::duty_cycle

Parameter	Type	Range	Description
freq¹	long	1 ... 1000000	frequency in Hertz
duty_cycle	word	1 ... 9999	duty cycle in units of 0.01%

Configures the PWM 0 (on relay output 0) with the specified parameters.

• Relay output 0 has to be set to PWM mode for this setting to become relevant (see Set Relays On/Off/PWM).
• On startup duty_cycle is set to 50% (5000) duty cycle automatically.
• ¹ DPM5050 is adjustable from 20 Hz to 1 MHz. [NACK] will be returned if a smaller or a greater value is applied.

Response:

[ACK]

Example

\iIP\0\L500\D8000

After sending this command, the PWM 0 on relay output 0 is running with 500 Hertz and a duty cycle of 80%. The resulting signal will have a rising edge every 2ms (1/500Hz = 0.002s) and stay high for 1.6ms (80% of 2ms).
