3.3 Current measurement (JP: 4, 9, 12, 13, 14, 16)
JP14
JP4, JP9, JP12, JP13
JP16
Note that the shunt for phase C usually is not mounted, since usually only two currents are
measured, and the third one can be calculated. In case of three independent currents, JP12
can be opened and the current can be measured using additional circuitry.

Jumper
JP12
JP13
JP14
JP16
JP4
JP9
This jumper can be used to select three different filter characteristics for the DC
bus current measurement.
These solder jumpers can be used to bypass the measurement shunts, when
they are not mounted or to reduce the power dissipation when not used by the
application.
This jumper selects an offset defined by R40 and R43 which is added to the
internal phase current values (2.5V by default, R99 = R102 = 10k). The default
setting (2-3) should usually not be changed.
