E1 OCD Interface connector location
2.4. Internal/External Power Stage Selection
The board offers the option of using either an internal MosFet power stage, or the complete interface to
connect an external power stage.
(Please note that the internal and external interfaces cannot be operated at the same time).
The power supplies, inverter drive signals and the other control and monitor signals are connected to the
external power stage connector J10. If an external power stage is connected, then the jumpers shown below
jumpers should be removed (NOT fitted).
When using the internal power stage the jumpers should be fitted and a connection to the external power stage
connector must not be connected.
The jumper selections are as described below:
 First jumper group:
o JP10 Internal U current analog channel selection
o JP11 Internal V current analog channel selection
o JP12 Internal W current analog channel selection
o JP13 Internal bus voltage analog channel selection
 Second jumper group:
o JP14 (H), JP15 (L) U phase driving signals
o JP16 (H), JP17 (L) V phase driving signals
o JP18 (H), JP19 (L) W phase driving signals
