The motor name plate data are only valid for one operating status (generally at
operating temperature). With the aid of the rotor adaption the operational performance
of motors > 4kW for the respective operating state (cold...warm... max. temperature)
can be optimized . This function should not be activated (because the system can
oscillate) for smaller motors or applications which do not reach the torque limit.
Prior to the activation the name plate data as well as the motor stator resistance
and leakage inductance must be entered. This function takes effect only with 300
rpm and approx. 10% of the rated inverter current. The function must always be
checked for the appropriate motor type, since with individual types a deterioration
of the drive characteristics can occur through the rotor adaption.
The adaption in a range of 0 (off) to 32767 can be adjusted with dS.7 (starting
value approx. 1000). This adjustment should be checked for correctness in several
operating ranges.
Bit Value Function
0-1 0 Rotor adaption off
1 Starting value 100 % default
2 Starting value 70 % default
3 Starting value 50 % default
2 0 not stored
1 Stored; by entering the motor data (dr-parameter) or d2.4 and
after Power-On the adaption factor (ru.59=adaption factor/
default*starting value bit 1) is loaded onto his starting value. During
the set change the current internal adaption factor is stored into
all appropriate motor sets and the last internal adaption factor
becomes valid in the new motor set.
3-4 0 Umax controller off
1 Umax controller on; sensible in the field weakening range,
particularly at activated rotor adaption, in order to limit the voltage
in the field weakening range to 100 %.
5-6 0 Flux controller off
1 Flux controller on; sensible for short acceleration times and
setpoint speed values within the field weakening range.
dS.8 and dS. 9 serve for the adaption of the proportional and integral factor of the
maximum voltage controller.
The flux controller is designed as PI-controller. The factors are adjusted with dS.11
and dS.12, dS.13 contains the limitation. For most applications it is not necessary
to activate the flux controller. Only in the case of short acceleration times and
setpoint speed values within the field weakening range the drive performance can
be optimized by activating the flux controller.
