Description
Motor supply is greater than 35 V DC or 25 Veff AC.
Motor supply is less than 35 V DC or 25 Veff AC.
Motor supply is separated from Motor Control board. The
Motor Control board must be supplied with 15 V DC (0.5
A) on J1.
Connects the R21 shunt resistor to external Operational
OpAmp circuitry and to the ST7FMC internal OpAmp.
Disconnects the R21 shunt resistor from the external
Operational OpAmp circuitry and to the ST7FMC internal
OpAmp, when using an external power stage through J4
or J6.
Connects the diagnostic output of the L6386 driver to the
MCES pin of the ST7FMC and enables the onboard
inverter power stage.
Disables the onboard inverter, when using an external
inverter power stage on J4 or J6.
Connects the heatsink thermal sensor (NTC2, located on
the bottom side of the PCB) to the AIN0 pin of the
ST7FMC.
Heatsink thermal sensor not connected to the AIN0 pin
of the ST7FMC.
ST7FMC internal OpAmp is used to amplify current
sensed by the R21 shunt resistor.
ST7FMC internal OpAmp not used. External OpAmp not
used. The ST7FMC MCCFI0 pin (comparator input) is
directly connected to the R21 shunt resistor to sense
current.
ST7FMC internal OpAmp not used. External OpAmp
used to amplify the current sensed by the R21 shunt
resistor. The ST7FMC MCCFI0 pin (comparator input) is
connected to the external OpAmp output.
A voltage of 15 V DC is applied on pin 9 of J4 (to supply
the external inverter and driver).
