Minimum Current

Hi. I am looking at using your SDC 1130 controller to drive a a small actuator motor. Motor is brushed type 12v 7A stall current, 1A unloaded current. I noticed in the data sheet that 1A is stated as minimum output current for these controllers. Is there likely to be a problem if the motor draws less than 1A?

My application will involve checking an analog sensor value every few minutes, determining if that value is in a rising or falling state and if it is within a set range and then making small adjustments to the actuator. These will be flicking the motor on in either direction for a fraction of a second at a time. Then waiting a while before looping back through the process. As far as I can tell from the documentation this should all be possible with the MicroBasic scripting language. Is this correct or is there something I have missed?

The 1A minimum in the datasheet is the minumm value the amps limit can be set. There is no minumum current for operation

Microbasic is totally suitable for your application
