Current Measurement (Jp: 43, 46, 48, 51, 59, 41, 47, 52, 53) - Fujitsu MOTORKIT-91F267-MC User Manual

3.10 Current measurement (JP: 43, 46, 48, 51, 59, 41, 47, 52, 53)

JP43, JP48, JP48, JP51
These jumpers select if the internal or external current signals are connected to
the MCU analog inputs AN0-AN3.
JP59 This solder jumper selects an offset defined by R99 and R102 which is added
to the internal phase current values (2.5V by default, R99 = R102 = 10k)
JP41, JP47, JP52, JP53
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.

In case an external power stage is used, the external power stage has to supply adequate
voltage levels of the measured values as well as conditioned signals.

Shunt for DC bus current measurement bypassed
The current of the internal power stage phase A is
measured
The phase A current sense signal of an external power
stage is passed to the MCU
The current of the internal power stage phase B is
measured
The phase B current sense signal of an external power
stage is passed to the MCU
The phase C current sense signal of an external power
stage is passed to the MCU
No connection to AN2
The current of the internal power stage DC bus is
measured
The DC bus current sense signal of an external power
stage is passed to the MCU
No offset on phase current values
offset defined by R99 / R102 is added to internal phase
current values
