Sequence

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 C00003

.

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 a fault

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!

From software version V4.0: If it is not possible to determine the so-called "Inverter error

characteristic", or if the results of the determination are incorrect, the device command

C00002

= "70: Load Lenze inverter characteristic" can be used to load a characteristic typical

for the device. Load Lenze INV characteristic
