• The torque proving sequence can start when the input signal RUNNING (B3 of
actual signal 03.02 ) is ”1”, in other words, when the converter is in operation. After
a successful sequence, the output signal TORQ PROV OK changes to “1”.
• If the function detects a fault during the sequence, it keeps the signal TORQ
PROV OK in value “0”, changes the signal TORQ PROVE FLT to “1” and trips the
drive.
• Torque proving reference is fixed to 30% of the motor torque (signal TORQ PROV
REF below).
• The torque proving reference is changed from 30 % to 10 % if the High-end limit
(parameter 10.12 HIGHEND PTR) is true and the drive receives a new start
signal given by the operator.
• The actual torque is read from the signal MOT TORQ (signal 01.05 ).
