7.2 b:Induction motor parameters
Induction motor parameters mainly include basic parameter settings, nameplate parameter
settings, electrical parameter settings and observations. In V/F control, one inverter can drive
multiple motors. At this time, the nameplate parameters should be set to the sum of the
parameters of the driven motors and a 10% margin is reserved. In vector control, one inverter
drives one motor as much as possible. After set the relevant parameters well, the motor
parameters self-learning must be performed. When it is necessary to use one inverter to drive
multiple motors through the contactor, the parameters of multiple motors should be set correctly
in this group of parameters and preparations must be made before operation.

The parameter used to select the second motor. When select the second motor, it is necessary to
combine with the multi-function input terminal (H0-XX = 31), only the parameter is set to 1 and
the multi-function input terminal with select the second motor function is ON, it will select the
second motor, otherwise still the first motor parameters valid. Please refer to the "

The electric motor selected by default.
1: The second motor
The second motor is selected in combination with the multi-function terminal as the current
drive motor, all the related parameters of the second motor are switched.

The parameter is used to set the self-learning type of the selected induction motor. For induction
motors, set the parameter and motor nameplate parameters firstly. Then press MULT to perform
motor parameters self-learning. Refer to the "
5.3 Induction Motor Self-learning
" for details of
the motor parameters self-learning. In vector control, it is necessary to perform full-mode
self-learning in order to ensure that good control performance is obtained.
0: Do not perform self-learning
Without self-learning requirements, the parameter is 0.
1: Perform DC mode self-learning
DC mode self-learning selected.
Suitable for V/F control mode or carrier frequency changes in vector control mode or full-mode
self-learning cannot be performed.
