Special customized PWM-analog output port
The following parameters need to be provided during customizing selection:
The output voltage of the required PWM;
The output frequency of the required PWM;
Confirm the numbers of customized PWM, up to 8 PWMs. (depending on analog outputs that customer make).
Customize whether PWM coexists with other analog quantities. (If the product is additionally equipped with analog, analog output terminals DA0~DA3 are a group, DA4~DA7 are a group. When QM3G customizes PWM, the output frequency can only be installed with other analogs in a group when the output frequency is only 21KHz ).
Special customized PWM - output frequency setting
When customizing the PWM, you do not need to use the PWM command, just set the special register and then turn on the hardware.
The special registers used by each analog quantity correspond to the following table.
| Analog output address | DA0 | DA1 | DA2 | DA3 | DA4 | DA5 | DA6 | DA7 |
| Duty cycle setting | D8050 | D8051 | D8052 | D8053 | D8054 | D8055 | D8056 | D8057 |
| PWM frequency division coefficient setting | D8268 | D8268 | D8268 | D8268 | D8278 | D8278 | D8278 | D8278 |
D8050 to D8057: the corresponding duty cycle, the value range is 0~4000, each 1 is 0.025%, and the total corresponds to 0~100%;
D8268 and D8278: the value range is 1~100000Hz (32 bits);
D8050 to D8057 ≦ D8268 and D8278
When D8268 and D8278 are powered on, the default setting is 21000Hz, and the power is not maintained. Program assignment is required when using.
