9.2.3.4 Motor Stopping Phase
At the end of the deceleration phase, the currents are
maintained in the coils at their actual DC level (hence
keeping the sine/cos ratio between coils) during 1/4
th
of an
electrical period at minimum velocity (thus 2 half-steps). The
currents are then set to the hold values, respectively
Ihold
x sin
(TagPos)
and
Ihold
x cos
(TagPos)
as illustrated
below. A new positioning order can then be executed.
9.2.3.5 Charge Pump Monitoring
If the charge pump voltage is not sufficient for driving the
high side transistors (due to a failure), an internal
HardStop
command is issued. This is acknowledged to the master by
raising flag <
CPFail
> (available with command
GetFullStatus1
).
In case this failure occurs while a motion is ongoing, the flag
<
StepLoss
> is also raised.
9.2.3.6 Electrical Defect on Coils, Detection and Confirmation
The principle relies on the detection of a voltage drop on at
least one transistor of the H-bridge. Then the decision is
taken to open the transistors of the defective bridge.
This allow to detect the following short circuits:
External coil short circuit
Short between one terminal of the coil and Vbat or Gnd
One cannot detect internal short in the motor
Open circuits are detected by 100% PWM duty cycle value
during a long time
Pins
