My homebrew H-bridge controller works fine with a linear actuator.
I also have a Polulu VNH5019 board which I like for its small size.
I read that people have successfully used it with the standard motor.ino and #define VNH2SP30 //
The problem is my actuator does not move very fast, even if I set the max servo speed to 100%.
The PWM sound from the actuator is also different.
i assume the PWM frequency from the nano determines the servo speed.
Does any one have an idea why the actuator moves so slow?
Without load the actuator draws less than 1Amp and the power supply is a 13,2V 30A unit.
