1-59 Flying Start Test Pulses Frequency
Default value: Size related
Parameter type: Range, 0 - 500%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: False
Asynchronous motor: Set the frequency of the flying start test pulses that are used to detect the motor direction. For asynchronous
motors, the value 100% means that the slip is doubled. Increase this value to reduce the generated torque. For synchronous motors,
this value is the percentage n
m,n
of the free-running motor. Above this value, flying start is always performed. Below this value, the
start mode is selected in parameter 1-70 Start Mode.

The following parameters are only available in FC 302:
Parameter 1-66 Min. Current at Low Speed
Parameter 1-67 Load Type
Parameter 1-68 Motor Inertia
Parameter 1-69 System Inertia
Parameter 1-60 Low Speed Load Compensation

Default value: 100%
Parameter type: Range, 0 - 300%
Setup: All setups
Conversion index: 0
Data type: Int16
Change during operation: True
Enter the % value to compensate voltage in relation to load when the motor is running at low speed and obtain the optimum U/f
characteristic. The motor size determines the frequency range within which this parameter is active.
