ED-DT318B
Drive Train Systems with Traction Control, Inverter/Controller, and Motor with 2 Speed Transmission
Min Value:
0
Max Value:
1
Units:
Boolean
Description:
True
The MCU is operating in Turbo Mode.
False
The MCU is operating in FOC Mode.
FOC is the most common mode of operation for DC electric motors. The MCU uses this mode of
operation at lower motor speeds. At higher motor speeds, the MCU uses a Danfoss Power
Solutions proprietary algorithm known as Turbo Mode.

Units:
Boolean
Description:
True
The MCU is using unfiltered speed values.
False
The MCU is using filtered speed values
The MCU derives speed from motor position signals. It normally filters those signals to reduce the
signal noise. The result of the filtering is that the speed used by the MCU slightly lags the actual
motor speed.
During normal operations, the lag is not enough to be significant. But, during a gear shift, the lag
is enough to cause a delay. The TCU eliminates the lag by signaling the MCU to use the unfiltered
position signals while a gear shift is in progress.
