Func
tions
High-torque Multi-operation
• When "sensorless vector control" or "0-Hz sensorless vector control" is selected with a single
Inverter, this function controls two motors of the same type to drive a single load.
• To use this function, you set the same parameters as when you select "Sensorless Vector Control"
(page 4-113) or "0-Hz Sensorless Vector Control" (page 4-114). However, set the motor
parameters as follows:
• Set motor parameters R1, R2, and L to one half of the set value for one motor.
• Set motor parameter Io to be twice the set value for one motor.
• Set motor parameter J to one half of the total moment of inertia of two motors and loads
connected to these motors.
• Select the motor capacity value closest to the total capacity of two motors.
• When different loads are driven with two motors, a fluctuation in one load affects the operating
condition of the other, which may hinder normal control.
To prevent this, be sure to operate a system in a way that the load driven by two motors is regarded
as one load.
Stabilization Parameter
• This function adjusts to reduce motor hunting.
• In case of motor hunting, check whether motor capacity H003/H203 and motor pole number
selection H004/H204 match your motor. If they do not, match them. If the motor's primary
resistance is smaller than that of the standard motor, increase the H006/H206/H306 set value
gradually. To run a motor with a capacity larger than the Inverter's rated capacity, reduce the set
value.
• Other than this function, the following methods are suggested to reduce hunting:
Lower the carrier frequency (b083). (Refer to page 4-65.)
Lower the output voltage gain (A045). (Refer to page 4-24.)
