Description
AKD supports several options to confirm a valid commutation after Wake and Shake has determined a
new commutation angle. In some mechanical situations, such as if motion is inhibited, it is possible for
Wake and Shake to select an incorrect angle. Commutation checks are designed to prevent unexpected
motion if this occurs.
0 = No Commutation Check
If No Commutation Check is selected, neither passive nor active commutations checks will be executed.
1 = Active Commutation Check (default)
In the default Active Commutation Check mode, AKD will make a short torque move after an angle has
been selected. If the motor fails to move in the expected direction, a fault will be generated.
2 = Passive Commutation Check
In the Passive Commutation Check mode, AKD will monitor torque commands and acceleration values
for 10 revolutions after Wake and Shake has completed. During this time, a fault will be generated if
unexpected motion is detected, such as if commanded torque and acceleration are in opposition direc-
tions. Note that this fault may also be reported if the motor experiences a large torque disturbance lasting
longer than WS.CHECKT.
