Drive operation limits. Limits 30
- / uint16 Displays limit word 1.
This parameter is read-only. Limit word 1 30.1
1 = Drive torque is being limited by the motor control
(undervoltage control, current control, load angle Torq lim b0
control or pull-out control), or by the torque limits
defined by parameters.
1 = Speed controller output is being limited by 25.11
Speed control min torque
Spd ctl tlim min b1
1 = Speed controller output is being limited by 25.12
Speed control max torque
Spd ctl tlim max b2
1 = Torque reference ramp input is being limited by 26.9
Maximum torque ref , source of 30.25 Maximum torque
Torq ref max b3
sel , 30.26 Power motoring limit or 30.27 Power
generating limit . See diagram on page 754 .
1 = Torque reference ramp input is being limited by 26.8
Minimum torque ref , source of 30.18 Minimum torque
Torq ref min b4
sel , 30.26 Power motoring limit or 30.27 Power
generating limit . See diagram on page 754 .
1 = Torque reference is being limited by the rush control
because of maximum speed limit (
30.12 Maximum
speed )
Tlim max speed b5
1 = Torque reference is being limited by the rush control
because of minimum speed limit (
30.11 Minimum speed )
Tlim min speed b6
1 = Speed reference is being limited by 30.12 Maximum
speed , or by maximum permanent magnet motor speed
limit based on DC voltage
Max speed ref lim b7
1 = Speed reference is being limited by 30.11 Minimum
speed , or by maximum permanent magnet motor speed
limit based on DC voltage
Min speed ref lim b8
1 = Frequency reference is being limited by 30.14
Maximum frequency
Max freq ref lim b9
1 = Frequency reference is being limited by 30.13
Minimum frequency
Min freq ref lim b10
Reserved b11
1 = Requested output frequency cannot be reached
because of switching frequency limitation (because of
eg. output filtering or ATEXrelated protections) Sw freq ref lim b12
(With permanent magnet motors and synchronous
reluctance motors, and externally-excited synchronous
motors in steady state) Load angle lim b13
1 = Maximum load angle is being limited, ie. the motor
cannot produce any more torque
(With externally-excited synchronous motors in dynamic
situations)
1 = Torque is being limited
Reserved b14…15
