2 Installation
Carefully remove the board from the shipping carton.
Check if there are any damages before power is applied to the evaluation board.
For the logic power supply a DC input voltage of 9V – 15V is recommended. The
positive voltage (+) must be connected to the center pin, and ground (GND) must be
connected to the shield of the connector X6!
By default, the DC bus is supplied through the screw terminal X11. Connect to an
adequate power supply for the motor in use (35V max.). Be aware that this input is not
protected against false polarity. Always connect ‘+’ to the terminal close to the upper
board edge, and GND to the one close to X6.
Further, it is strongly recommended to use a laboratory DC power supply with
adjustable current limitation with this board. Otherwise, in case of software or
hardware malfunctions or false configurations, high currents can flow and damage
the power supply and/or the board and lead to overheating by excessive power
dissipation.
After power-on, the power-on LEDs (LED2 and LED3) should be on, depending on the
configuration of the corresponding jumpers. If the LEDs do not light up, switch off the power
supply and check the jumper settings according to the desired configuration.
Depending on the power supply used for the DC link input, it might be necessary to protect
the power supply against reverse current. This can occur when shutting down the power
supply with the board attached, or when an attached motor is externally accelerated or
quickly decelerated and thereby works as a generator. This protection can be done by a
diode of sufficient current capability. Since many power supplies are vulnerable to this issue,
inserting a diode is recommended.
The board is shipped with power transistors in a D2PAK package. For additional flexibility,
there are also soldering options for power MOSFETS in TO-220 packages, which can be
mounted on external heat sinks. In this case, probably also the current measurement shunts
should be replaced with a smaller value or bypassed to reduce heat.
