510 Positive feedback identified
Cause Ramp-up:
The actual rotor position and the position information read-out of the
encoder were compared with one another while booting and a deviation
of more than 45 Degrees was identified, P1011[10].
Operational:
The acceleration/velocity direction is different than the torque/force direction.
This monitoring function can be set using P1645 and P1646.
Remedy -- This alarm can also occur when axes are mechanically blocked.
Check the fault cause analog to Alarm 605 ”Speed controller output
limited”.
-- Operation may only be resumed after the fault has been removed
otherwise there is a danger of uncontrollable motion.
Ramp-up:
-- The deviation is due to dirt on the encoder or incorrect mounting/
installation of the encoder or encoder cable.
Operational:
-- If the load oscillates strongly increase the delay for the monitoring
(P1645).
-- Caution : The value in P1645 influences the duration of the axis
motion, triggered by positive feedback until the fault responds.
-- Check the encoder: Mounting, dirt, absolute track fault, lost pulses,
encoder cable
