frequency also results in a higher motor slip, which is proportional to the accelerating torque.

Settings that are required
In order to achieve a satisfactory control response, as a minimum you must set the partial
functions – shown with gray background in the diagram above – to match your particular
application:
● Motor and current model: In the quick commissioning, correctly set the motor data on the
rating plate corresponding to the connection type (Y/Δ), and carry out the motor data
identification routine at standstill.
● Speed limits and torque limits: In the quick commissioning, set the maximum speed
(p1082) and current limit (p0640) to match your particular application. When exiting quick
commissioning, the inverter calculates the torque and power limits corresponding to the
current limit. The actual torque limits are obtained from the converted current and power
limits and the set torque limits.
● Speed controller: Start the rotating measurement of the motor data identification. You
must manually optimize the controller if the rotating measurement is not possible.
The load falls due to incorrect closed-loop control settings
For encoderless vector control, the inverter calculates the actual speed based on an
electric motor model. In applications with pulling loads - e.g. hoisting gear, lifting tables or
vertical conveyors - an incorrectly set motor model or other incorrect settings can mean that
the load falls. A falling load can result in death or serious injury.
• Correctly set the motor data during the quick commissioning.
• Carry out the motor data identification.
• Correctly set the "Motor holding brake" function.
• For pulling loads, carefully comply with the recommended settings for vector control.
