P7-03 | Rescue Mode Speed | Hz / rpm / ft/s / m/s | 5.00Hz | P8-02 ... P8-01 | RW | Y *Does not take effect until next travel | 1 = 0.1 Hz | 2 | 22BFh | 0 | 703 |
This parameter defines the motor speed during rescue mode operation (when Rescue mode Input is activated), the value is also controlled internally by the power limit function based on the UPS rating entered into parameter P7-04.
The actual achievable speed will be limited depending on a number of factors such as DC bus voltage level, motor, travel speed, system efficiencies, estimated value can be calculated as follows :
It should also be noted that the level of motor load will affect the available DC bus Voltage; in some cases it may be necessary to reduce the Rescue Speed further in order to prevent nuisance Under Voltage (“U-volt”) trips.
