sennian WROTE:I first tested my new MDS40A smart driver by connecting a 12V source to the power source, a motor at the motor terminals. I set up mode for pwm input mode and connect it to my microcontroller. After testing for a while, when I removed the motor connection and reconnect it afterwards, it doesn't work anymore. Tried even pressing the button A and B but nothing happens (button A and B are supposed to work if there's power source and motor connected isn't it) and the error LED kept blinking for 2 times. Can anyone tell me what is wrong? Why even the A button and B button don't work
The Analog/PWM signal to stop the motor (2.5V if Sign-Magnitude mode is off, 0V otherwise) must be available when the SmartDrive40 is turned on. Else, the driver will show Input Error until the correct signal is available.
