Stop!
Motors with electronic nameplates (ETS) must not be operated on 8400 controllers!

Note!
Sensorless vector control (SLVC) and sensorless control for synchronous motors (SLPSM)
in particular requires the motor data parameters to be set. The motor data comprise the
data of the motor nameplate and the data of the motor equivalent circuit.
If the motor has been selected via the motor catalogue of the »Engineer« or the motor
data have been adapted offline using the »Engineer«, all motor data must then be
copied to the controller and saved power-failure-proof to the memory module (device
command: C00002/11 ) when an online connection has been established.

Note!
Setting a rated motor frequency with a decimal position
If the motor has a rated motor frequency with a decimal position (e.g. motor nameplate
data "23.7 Hz"):
• Up to and including version 02.xx.xx , the following motor nameplate data must be
increased by a factor of 10:
• C00089 : Rated motor frequency
(a value of "23.7 Hz", for instance, must be increased to 237 Hz.)
• C00081 : Rated motor power
• C00087 : Rated motor speed
• C00090 : Rated motor voltage
• From version 12.00.00, the rated motor frequency must be entered without decimal
position to clearly identify the right motor type. (a value of "23.7 Hz", for instance,
must be set to 23 Hz in C00089 )
• C01000 displays the set motor type (ASM or PSM).
• C00969 displays the set number of motor pole pairs.
• From version 14.00.00 onwards , the motor type (ASM or PSM) can also be set
manually in C01001/1 for a clear identification.

Note!
If a rated motor speed is set for an asynchronous motor (ASM) in C00087 which
corresponds to a very high slip speed, the number of pole pairs is identified incorrectly.
Moreover, a synchronous motor (PSM) is detected instead of an asynchronous motor
(ASM) at certain slip speeds. Detailed information and possible remedies can be found
here:
