3.13 Hall sensor and encoder interface (JP: 54, 56, 57, 60, 61, 62)

JP54, JP56, JP57

These jumpers select whether the hall sensors are connected to the

input capture pins IC0-IC2 or to the external interrupts INT0-INT2.

JP60, JP61, JP62

These jumpers connect the encoder interface (J13) to IC0 (Ch. A), IC1

(Ch. B) and INT3 (Index).

3.14 Over-current / Over-voltage DTTI (JP: 55, 58)

JP55

The over-current detection circuit (U9A) is connected to the MCU DTTI input.

JP58

The over-voltage detection circuit (U9B) is connected to the MCU DTTI input.

Both JP55 and JP58 can be set, since they are connected by diodes (wired-OR).

The threshold voltage for DTTI can be adjusted with the potentiometers P6 (current) and P7

(voltage).

Since it monitors the DC bus current, the over-current detection only works if the DC bus

current measurement is not bypassed (JP53 must be open).
