9.4.3 Drive setting
The drive setting function extends the start-up facilities of quick
parameterization.
During the drive setting, the control electronics is informed about the
incoming voltage supply with which the drive converter is operating,
about the connected motor and about the motor encoder. In addition,
the motor control (V/f open-loop control or vector control) and the pulse
frequency are selected. If required, the parameters necessary for the
motor model can be calculated automatically. Furthermore, the
normalization values for current, voltage, frequency, speed and torque
signals are determined during the drive setting.
For start-up of the induction motor, first enter the manufacturer's
parameters completely (see below):
♦ In doing so, you must observe whether the induction motor has a
star or a delta connection.
♦ You must always use the S1 data from the rating plate.
♦ You must enter the r.m.s. base frequency of the rated voltage and
not the total r.m.s. value (including harmonic content) for converter
operation.
♦ You must always enter the correct rated motor current
P102 (rating
plate). If there are two different rated currents on the rating plate for
special fan motors, you must use the value for M ~ n for constant
torque (not M ~ n
2
). A higher torque can be set with the torque and
active-current limits.
♦ The accuracy of the rated motor current has a direct effect on the
torque accuracy, as the rated torque is normalized to the rated
current. If a rated current is increased by 4 %, this will also
approximately result in a 4 % increase in the torque (referred to the
rated motor torque).
♦ For group drives, you have to enter the total rated current
P102 = x*I
mot,rated
♦ If the rated magnetizing current is known, you should enter it during
the drive setting in
P103 (in % I
mot,rated
). If this is done, the results
of the "Automatic parameterization" (P115 = 1) will be more precise.
