Motor and V/f Pattern Setup
The L7 inverter supports 2 motor settings (main motor and door motor, E2/E4- parameters) for V/f con-
trol, Open Loop Vector and Closed Loop Vector for IM. The active motor setup can be selected by a digital
input.
Closed Loop Vector Control for PM supports 1 motor setting (main motor, E5- parameters) only.
îš‹ Setting Motor Parameters for Induction Motors (Motor 1 and 2)
In order to achieve the maximum performance the V/f pattern and the motor data must be set correctly.
The number of motor parameters which can be set, depend on the selected control mode.
In the vector control methods the motor parameters can be set automatically by using the autotuning function
(refer to page 4-4, Autotuning).
However, if autotuning does not complete normally, the parameters must be set manually like described
below.
