Description
Drive operation limits.
Displays limit word 1.
This parameter is read-only.
Description
1 = Drive torque is being limited by the motor control (undervoltage
control, current control, load angle control or pull-out control), or by
the torque limits defined by parameters.
1 = Speed controller output is being limited by
min torque
1 = Speed controller output is being limited by
max torque
1 = Torque reference ramp input is being limited by
torque ref, source of
motoring limit or 30.27 Power generating
page 654.
1 = Torque reference ramp input is being limited by
torque ref, source of
motoring limit or 30.27 Power generating
page 654.
1 = Torque reference is being limited by the rush control because of
maximum speed limit
1 = Torque reference is being limited by the rush control because of
minimum speed limit
Maximum speed
based on DC voltage
maximum permanent magnet motor speed limit based on DC
voltage
1 = Frequency reference is being limited by
frequency
1 = Frequency reference is being limited by
frequency
1 = Requested output frequency cannot be reached due to
switching frequency limitation (because of output filtering or ATEX
related protections)
