Trigger Description
Leg current exceeded
within 16ms of bad
position A trigger occurs if a bad position signal event and an over leg current event
occur within 16 milliseconds of each other.
Mechanical Power
reaches trigger level A mechanical power level is set, and a trigger occurs when the Danfoss Power
Solutions motor’s mechanical power exceeds this level.
Motoring is limited
below trigger level
percentage A percentage level is set, and the trigger occurs when the limit acting on the
motoring torque is below that level.
Over voltage A trigger occurs when the bus voltage is over the maximum battery voltage.
Position signal is bad A trigger occurs when the position signal is judged bad.
Position signal is
searching
A trigger occurs if the position signal had been lost and the controller is
attempting to re-sync to the position signal.
Position signals are
noisy A trigger occurs when electrical noise is detected on the position sensor signals.
Regen is limited below
trigger level percentage A percentage level is set, and the trigger occurs when the limit acting on the
regeneration torque is below that level.
Regen switch changes
A trigger occurs when the state of the regen switch changes from open to closed
or from closed to open.
Speed reaches trigger
level 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.
Stall conditions occur 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).
Stall conditions stop A trigger occurs when the controller begins limiting its output because it has
detected stall conditions. See Stall conditions occur above.
Torque (actual) reaches
trigger level A Newton meter level is set, and the trigger occurs when the calculated torque
passes through that level from either direction.
Torque (desired)
reaches trigger level A Newton meter level is set, and the trigger occurs when the demanded torque
passes through that level from either direction.
Turbo Mode exits 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.
