Mating connector: Tycos electronics (formerly AMP) MTA-100 series (3-640440-2) 1 2 Pin Label Description 1 +U Module + driver stage power supply input 2 GND Module ground (power supply and signal ground) Table 4.1: Connector for power supply Please note, that there is no protection against reverse polarity and only limited protection against voltages above the upper maximum limit. The power supply typically should be within a range of +9 to +28.5V. When using supply voltages near the upper limit, a regulated power supply is mandatory. Please ensure that enough power filtering capacitors are available in the system (2200µF or more recommended) in order to absorb mechanical energy fed back by the motor in stalling conditions and in order to prevent any voltage surge e.g. during power-on (especially with longer power supply cables as there are only ceramic filter capacitors on-board). In larger systems a zener diode circuitry might be required in order to limit the maximum voltage when the motor is operated at high velocities. The power supply should be designed in a way that it supplies the nominal motor voltage at the desired maximum motor power. In no case shall the supply value exceed the upper voltage limit. To ensure reliable operation of the unit, the power supply has to have a sufficient output capacitor and the supply cables should have a low resistance, so that the chopper operation does not lead to an increased power supply ripple directly at the unit. Power supply ripple due to the chopper operation should be kept at a maximum of a few 100mV. Guidelines for power supply: a) keep power supply cables as short as possible b) use large diameters for power supply cables c) add 2200µF or larger filter capacitors near the motor driver unit especially if the distance to the power supply is large (i.e. more than 2-3m) 4.2.2 Motor connector A 3-pin Tyco electronics (formerly AMP) MTA-100 series connector (3-640456-3) is used as motor connector on-board.
