New Speed Controller Announced

[Gdeaver]

One thing teams will have to be aware of is that according to the manual, if there is an over current or temperature condition, the motor controller will shut down. The PWM input will have to go to neutral for the motor controller to go active again. For 2009 we will not have any feed back from the motor controller to know that it is in shut down. Teams will have to decide how to detect and reset the motor controller. For the drive this will probably be the responsibility of the driver. For arms and other uses a controller reset button may be useful. Going forward in 2010 with the CAN control method this condition can be handled in software and the user can be alerted that a shut down occurred. Also with proper monitoring code, the controller could implement strategies to stop the controller from going into hard shut down. First team are used to using total open loop controllers and have only been protected from faults by the circuit breakers. How to deal with intelligent controllers is something teams will have to work on in the future. This year without 2 way communication with the motor controller, the victors may be a better choice for uses other than drive motors.
