• The drive controller must be designed for the corresponding output (P

= 1.73 · P

).
• B12 (I-nominal) is parameterized to the appropriate nominal motor current
(I
delta
= 1.73 · I
star
).
Correction factor for the pitch of the V/f characteristic curve. The pitch with V/
f-factor = 100 % is determined by V-nominal (B14) and f-nominal (B15).
Boost refers to an increase in voltage in the lower speed range, which makes
a greater starting torque available. A boost of 100 % means the nominal motor
current will flow at 0 Hz. To determine the required boost voltage, the stator
resistance of the motor must be known.
You must therefore always perform B41 autotuning for motors without an
electronic rating plate.
For STOBER standard motors, the stator resistance of the motor is defined
when the motor is selected.
Clock frequency of the drive controller power board.
Increasing the clock frequency improves the control dynamics and reduces the
amount of noise produced, but also leads to increased losses (derating of the
power stage R04, R26).
In some operating states the clock frequency is changed by the drive controller
itself. The currently active clock frequency is displayed in E151.

of the motor winding in ohms. Processing with this
parameter is only possible for third-party motors. The value can be autotuned
with action B41 autotuning.
Frequency of the voltage applied to the motor.
Display of the current speed reference value (RV) in user units based on the
profile generator and the v-RV low pass. The total of the position controller
output and speedFeedFwd (=speed controller reference value) is displayed in
Position operating mode. E06 shows the same value in reference to the motor
shaft.

Information
The factory setting of this parameter depends on B20. If a
synchronous servo motor or synchronous linear motor is used, the
value 8:8kHz is entered in B24. If an asynchronous machine is
used, B24 has a value of 4:4kHz.
