Application Guide
Use this parameter to set the maximum power limit of the generating side.
7.266 (ID 1316) Response to Brake Fault
Location in the menu: P3.14.7
Use this parameter to set the response type to a brake fault.
7.267 (ID 1412) Torque Stabilator Gain
Location in the menu: P3.1.4.13.1
Use this parameter to set the gain of the torque stabilator in an open loop control operation.
7.268 (ID 1413) Torque Stabilator Damping Time Constant
Location in the menu: P3.1.4.13.3
Use this parameter to set the damping time constant of the torque stabilizer.
7.269 (ID 1414) Torque Stabilator Gain at Field Weakening Point
Location in the menu: P3.1.4.13.2
Use this parameter to set the gain of the torque stabilator at field weakening point in an open loop control operation. The torque
stabilizer stabilizes the possible oscillations in the estimated torque.
Two gains are used. TorqStabGainFWP is a constant gain at all the output frequencies. TorqStabGain changes linearly between the
zero frequency and the field weakening point frequency. The full gain is at 0 Hz and the gain is zero at the field weakening point.
The figure shows the gains as a function of output frequency.

7.270 (ID 1424) Restart Delay
Location in the menu: P3.2.11
Use this parameter to set the time delay during which the drive cannot be restarted after coast stop (flying start not in use).
7.271 (ID 1431) Supervision #1 Item Selection
Location in the menu:
• INU application: P3.8.1
• AFE application: P3.7.1
Use this parameter to select the supervision item. The output of the supervision function can be selected to the relay output.
7.272 (ID 1432) Supervision #1 Mode
Location in the menu:
• INU application: P3.8.2
•
AFE application: P3.7.2
Use this parameter to set the supervision mode.
When the 'Low limit' mode is selected, the output of the supervision function is active when the signal is below the supervision
limit.
