12v actuator, no encoder, no feedback of any kind
i need onboard PWM , speed control, BUT
i need 2 speed control setting, 1 for each direction
we will be just toggling direction only
we need faster in our open condition
and slower in our close condition
the MD30c rb-cyt-133 has pwm and speed pot
but seems to have only 1 speed control, for both directions
is there a similar unit that can set speeds in both directions ?
Hi,
Well, you can most likely achieve what you want with this board and some clever design. In the manual for this product (page 6-7), you will notice it can use either the internal pot for speed control, the external pot or simply use an external PWM signal directly. This means there are many ways to achieve your goal.
The simplest in the modern, post-Arduino microcontroller board world is to use a small microcontroller to control the motor controller. It would simply be connected to a switch or other control and use that input to set the motor controller to perform what is required.
Alternatively, you could use an electrical solution, too. Two potential ideas come to mind here:
I’m sure there are a few more ideas that would allow this, too.
As for other controllers, you may be interested in the RB-Dim-47 (2x32 A, 6-24 V DC). It has a special User Mode (manual, page 31) setting that allows for quite a lot of options, possibly what you are looking for, too. You can read more about the the DEScribe software on page 34+.
We hope this helps.
Sincerely,
