Sensorless Vector Control Operation Setting Details for Induction Motors
Code Description
Cn.09 PreExTime Sets pre-excitation time. Pre-excitation is used to start the operation
after performing excitation up to the motor’s rated flux.
Cn.10 Flux Force Allows for the reduction of the pre-excitation time. The motor flux
increases up to the rated flux with the time constant CN.09 as shown in
the following figure. To reduce the time taken to reach the rated flux, a
higher motor flux force, Cn.10 must be provided. When the magnetic flux
reaches the rated flux, the provided motor flux base value, Cn.10 is
reduced.
Cn.11 Hold Time Sets the zero-speed control time (hold time) in the stopped position.
When a stop command is applied, the motor decelerates to zero speed.
The inverter applies an ouput (at zero speed) to hold the motor for the
Hold Time, Cn.11.
Cn.21 ASR-SL P Gain1,
Cn.22 ASR-SL I Gain1 Speed Controller P & I Gains. Changes the speed PI controller gains.
Speed controller P Gain1 is a proportional gain for the speed deviation.
If speed deviation becomes higher than the torque, the output command
increases accordingly. As the value increases, the faster the speed
deviation decreases. The
speed controller I gain1 is the integral gain for
speed deviation. It is the time taken for the gain to reach the rated torque
output command while a constant speed deviation continues. The lower
the value becomes, the faster the speed deviation decreases.
