A trigger occurs if a bad position signal event and an over leg current event
occur within 16 milliseconds of each other.
A mechanical power level is set, and a trigger occurs when the Danfoss Power
Solutions motor's mechanical power exceeds this level.
A percentage level is set, and the trigger occurs when the limit acting on the
motoring torque is below that level.
A trigger occurs when the bus voltage is over the maximum battery voltage.
A trigger occurs when the position signal is judged bad.
A trigger occurs if the position signal had been lost and the controller is
attempting to re-sync to the position signal.
A trigger occurs when electrical noise is detected on the position sensor signals.
A percentage level is set, and the trigger occurs when the limit acting on the
regeneration torque is below that level.
A trigger occurs when the state of the regen switch changes from open to closed
or from closed to open.
A signed RPM level is set, and the trigger occurs when the motor speed passes
through that level from above or below. Remember that if spinning in reverse,
then this value must be signed to cause a trigger.
A trigger occurs when the controller begins limiting its output because it has
detected stall conditions (also called locked rotor, when large torques are
requested but the motor is not spinning).
A trigger occurs when the controller begins limiting its output because it has
detected stall conditions. See Stall conditions occur above.
A Newton meter level is set, and the trigger occurs when the calculated torque
passes through that level from either direction.
A Newton meter level is set, and the trigger occurs when the demanded torque
passes through that level from either direction.
A trigger occurs when Turbo Mode exits. Turbo Mode is Danfoss Power
Solutions' proprietary control algorithm that produces outstanding power and
efficiency at high speeds.
