NOTE
Up to and including firmware status V 5.2, correct evaluation of the nameplate after a change in
parameter B06 does not occur until a device new start. Starting with firmware status V 5.3, the
nameplate is evaluated immediately.
The parameter G06 only appears for inverters of the MDS 5000 series.

B10
Axis, OFF
r=1, w=1
Motor-poles: Results from the nominal speed nNom [Rpm] and the nominal frequency f [Hz] of
the motor. B10=2·(f · 60 / nNom). Correct entry of the number of poles is mandatory for the inverter
to function.
Value range: 2 ... 6 ... 16

B11

Nominal motor power: Nominal power in kW as per nameplate. If only the nominal torque Mn
is known instead of the nominal power, B11 must be calculated from Mn [Nm] and the nominal
speed n [Rpm] based on the following formula: B11=Mn · n / 9550.

Nominal motor voltage: Nominal voltage as per nameplate. Since, with asynchronous motors,
the type of switching (Y/
Δ) must be adhered to, make sure that the parameters B11 ... B15 match!
Value range in V: 0 ... 400 ... 480
Fieldbus: 1LSB=1V; Type: I16; (raw value:32767 = 2317 V); USS-Adr: 02 03 80 00 hex

Nominal motor frequency: Nominal frequency of the motor as per nameplate. Parameters
B14 and B15 specify the inclination of the V/F characteristic curve and thus the characteristic of the
drive. The V/F characteristic curve determines the frequency (B15: f-nominal) at which the motor
will be operated (B14: V-nominal). Voltage and frequency can be linearly increased over the
nominal point. Upper voltage limit is the applied network voltage. STÖBER system motors up to a
size of 112 offer the possibility of star/delta operation. Delta operation with 400 V permits a power
increase by the factor of 1.73 and an expanded speed range with constant torque. In this type of
circuit, the motor requires more current. It must be ensured that:
- The frequency inverter is designed for the corresponding power (P
Delta = 1.73 · PStar).
- B12 (I-nominal) is parameterized for the corresponding nominal motor current (IDelta = 1.73 · IStar).
With quadratic characteristic curve (B21=1), nominal frequencies are limited via 124 Hz internally to
124 Hz.
Value range in Hz: 0.0 ... 50,0 ... 1600.0
Fieldbus: 1LSB=0,1Hz; Type: I32; (raw value:2147483647 = 512000.0 Hz); USS-Adr: 02 03 C0 00 hex
