304 Limit Status
Displays the limit status of conditions that may be limiting the current reference or torque reference.
• Bit 0 [+MCS Iq Lim] indicates that torque producing current is at its positive limit.
• Bit 1 [+MCS Ws Lim] indicates that flux producing torque is at its positive limit.
• Bit 2 [0 Ia from +] indicates that torque producing current is limited to zero from the positive direction - refer to Par 353 [Iq Actual Lim].
• Bit 3 [+Iq Calc] indicates the calculation for torque producing current has reached its positive limit.
• Bit 4 [+Current Lim] indicates that the current reference has reached the positive Motor Current Limit set by Par 356 [Mtr Current Lim].
• Bit 5 [+DriveProtOL] indicates that the current reference has reached the positive current limit set by the Open Loop Inverter Overload, shown in Par 343 [OL
OpnLp CurrLim].
• Bit 6 [+DriveProtCL] indicates that the current reference has reached the positive current limit set by the Closed Loop Inverter Overload, shown in Par 344
[OL ClsLp CurrLim].
• Bit 8 [+Torq Limit] indicates that the torque reference has reached the Positive Torque Limit set by Par 125 [Torque Pos Limit].
• Bit 9 [Mtrng PwrLim] indicates that the torque reference is being limited by the Motoring Power Limit set by Par 127 [Mtring Power Lim].
• Bit 10 [+Torq CurLim] indicates that current reference has reached the Actual Torque Producing Current Limit set by Par 353 [Iq Actual Lim].
• Bit 11 [Atune Tq Lim] indicates that the torque reference is being limited by Par 129 [Atune Torq Ref].
• Bit 12 [+0 Torq Ena] indicates that the torque reference is limited to zero because Par 157 [Logic Ctrl State] bit 9 [Torq Ref En] is off.
• Bit 13 [+0 Curr Ena] indicates that the current reference is limited to zero because Par 157 [Logic Ctrl State] bit 11 [CurrRef En] is off.
• Bit 16 [-MCS Iq Lim] indicates that torque producing current is at its negative limit.

• Bit 20 [-Current Lim] indicates that the current reference has reached the negative Motor Current Limit set by Par 356 [Mtr Current Lim].
• Bit 21 [-DriveProtOL] indicates that the current reference has reached the negative current limit set by the Open Loop Inverter Overload, shown in Par 343
[OL OpnLp CurrLim].
• Bit 22 [-DriveProtCL] indicates that the current reference has reached the negative current limit set by the Closed Loop Inverter Overload, shown in Par 344
[OL ClsLp CurrLim].
• Bit 24 [-Torq Limit] indicates that the torque reference has reached the Negative Torque Limit set by Par 126 [Torque Neg Limit].
• Bit 25 [Regen PwrLim] indicates that the torque reference is being limited by the Regenerative Power Limit set by Par 128 [Regen Power Lim].
• Bit 26 [-Torq CurLim] indicates that current reference has reached the Actual Torque Producing Current Limit set by Par 353 [Iq Actual Lim].
• Bit 27 [Bus Reg Tq Lim] indicates the bus voltage regulator is active and limiting the regenerative torque.
• Bit 28 [-0 Torq Ena] indicates that the torque reference is limited to zero because Par 157 [Logic Ctrl State] bit 9 [Torq Ref En] is off.
• Bit 29 [-0 Curr Ena] indicates that the current reference is limited to zero because Par 157 [Logic Ctrl State] bit 11 [CurrRef En] is off.
