Principle of current and torque limitations (closed-loop)
•
separate limitation of current and torque/force (separated via
P-0-0051, Torque/force constant
)
•
unipolar limits for torque/force (S-0-0082, S-0-0083)
•
absolute current limitation by minimum value of
S-0-0110, Amplifier
peak current
and
S-0-0109, Motor peak current
•
dynamic current limitation:
•
for currents above the 1.15.-fold motor current at standstill
•
based on the amplifier temperature model (E8057/E2061)
•
stall current protection for asynchronous motors
•
