PS105F6A Software Update: New Operating Modes

PS105F6A Software Update Overview

The PS105F6A software has been updated with important changes.

With this update, the module gains more precise duty cycle control and new operating modes for adjustable PWM signal generation. These improvements make the module more flexible in test setups, driver experiments and R&D applications where signal parameters need to be changed during operation.

New Operating Modes

The updated software includes three operating modes.

In INS mode, each parameter change is applied directly to the output signal. This mode is useful when immediate response is required during manual adjustment or signal testing.

In LTN mode, parameter changes are applied after the rotary encoder remains stationary for a short time. This helps prevent every small encoder movement from being processed instantly and provides a more controlled adjustment behavior.

In ramp transition mode, the user can define a target frequency and/or duty cycle value together with a transition time. After the ramp transition is started, the signal parameters move gradually toward the target values.

More Precise PWM Adjustment

One of the main improvements in this update is more precise duty cycle control.

This allows the output signal to be adjusted more accurately, especially in applications where small duty cycle changes affect the behavior of the circuit under test. Combined with the new operating modes, this provides a more practical control structure for experimental switching circuits.

Ramp Transition Support

Ramp transition mode is useful when sudden changes in signal parameters are not preferred.

Instead of applying the target frequency or duty cycle immediately, the module can move toward the selected values over a defined time interval. This can be helpful in motor control tests, load transition experiments and switching applications where gradual parameter changes are required.

Conclusion

The PS105F6A software update improves the usability of the module by adding more precise duty cycle control and three operating modes: instant update, latency-based update and ramp transition. These changes make PS105F6A more flexible for PWM signal generation, gate driver tests and R&D-oriented switching applications.
