CM3 PWM Module RAMP Control

CM3-SP32PWM RAMP Control​

  1. The output control of the CM3-SP32PWM is available from 1 ~ 4,000pps.
  2. RAMP is supported when the frequency value is changed.
    • Please refer to the RAMP instruction.
  3. The frequency RAMP feature changes according to the frequency RAMP control time.
    • If the set time is 0, the frequency RAMP changes immediately.
  • The setting value for frequency can be changed during the RAMP operation.
    • However, changing the frequency RAMP control time can only be applied AFTER changing the frequency value.


  1. The CM3-SP32PWM's output DUTY cycle ratio can be controlled from 0% ~ 100%.
    • Please refer to the DUTY instruction.
  2. There is support for the RAMP when DUTY cycle ratio changes feature.
  3. The DUTY cycle RAMP function changes according to the frequency RAMP control time.
    • It instantly changes if the DUTY cycle RAMP time is set to 0.
  • If the DUTY RAMP control time is changed during the RAMP operation, the change will be applied in the NEXT operation.


  1. There are a maximum of 12 channels available for high-speed pulse-width modulation output that supports the RAMP feature.
    • Frequency RAMP and DUTY cycle RAMP operate individually.
