Does the controller need to regulate torque? Parking Brake required: Yes No (Circle one.) How is braking controlled? Do any motion control profiles need to be implemented (trapezoidal, S-curve, etc )? What is the maximum torque and power to be delivered by the motor? How long must this be sustained for? What is the max electrical power delivered by the controller to the motor? How long must the controller be able to sustain maximum power delivery? Does the controller need to protect the motor from overheating and abuse situations? How is this to be accomplished? If the controller drives more than one motor, is it necessary to synchronize the speed or delivered torque of the motors? -2-

How is power provided to the controller?

3 Power Requirements Operating voltage: What is the minimum and maximum voltage that controller is expected to operate within? Voltage extremes: What is the maximum voltage that the controller is expected to survive? Wiring considerations: Are the wires heavy enough to transfer the required power with minimal loss? How is power provided to the controller? Is the controller directly powered by a battery, or is the power switched through some other circuit (example: controller is powered when ignition is switched on)? Sleep modes: Is the controller required to implement a low power sleep mode? What are the requirements? How/when will the system enter and leave sleep mode? Controller Input Requirements What are the input circuits provided to the controller? Are they digital or analog? What are the requirements for the controller interface circuitry? Digital inputs: What is their configuration? Push-Pull? Open drain? Voltage range? Whetting current? Analog inputs: What is the voltage range of the input? What is the impedance of the circuit? Periodic waveforms: Any waveform input specified? What is their frequency, duty cycle, amplitude wave shape, etc Other inputs: are there any special purpose inputs provided to the module (example: sensors)? What are their requirements? Communication: Is the module expected to communicate with the outside world? What are the communication requirements, if any? How is the bus terminated? Controller Output Requirements What circuits will the controller drive? What is their configuration (digital, analog, PWM, etc)? Is the controller required to detect open and/or shorted output circuits? What failsafe modes if any must be supported? What are the power requirements for the output circuits? Any high power circuits? Any periodic output waveforms? What is their frequency, duty cycle, amplitude, wave shape, etc -3-
