Process
The detection of the inverter characteristic is started if
• no other identification is active,
• no error has occurred, and
• no test mode is activated.
If one of the above conditions is not met, the procedure is cancelled and the corresponding
device command status is indicated under
If all conditions are met, the motor is energised with a maximum direct current corresponding to
the lower of the following two values:
• Ideally, the first value should be reached, the second value is to ensure that the load on the
machine is not too high during this test.
During the procedure, the motor current rises up to the specified maximum value and falls back to
"0" to repeat the cycle with a negative current sign.
• The maximum value is reached four times.
• The switching frequency is set to rated switching frequency and after the procedure, it is reset
to the original value.
• If the switching frequency should be changed later during operation, the characteristic will
be adapted to the current switching frequency.
In the event of an error
If an error occurs during the procedure or the pulse inhibit gets active (e.g. due to short-time
undervoltage), the procedure is terminated with controller inhibit and the detected characteristic is
not considered.
Tip!
If it is not possible to determine the "Inverter error characteristic", or if the results of the
determination are incorrect, the device command
= "70: Load Lenze inverter
characteristic" can be used to load a characteristic typical for the device.
