3. Functional Description

3.1 Performance of vector control with resolver

Using the sinusoidal wave feedback signal from the resolver installed on the motor shaft or load rotation shaft, vector
control with sensor can be conducted.
Speed control operation: 0 speed to 150% torque,
Torque control operation: Torque control accuracy: ±10%

3.1.1 Parameter setting for vector control with resolver

During operation with vector control with sensor, it would be necessary to set the following parameters shown
below.
■ Set V/f pattern

Function
Title
Pt V/f Pattern
When conducting vector control with sensor (speed/torque control) with this board option, <Pt> = "10", "11", "12" should
be set.
For torque control operation, it is necessary to allocate control switching (torque/position) to one of the terminal function
selection <F111> to <F118> (input terminal function selection 1 to 8) (when <CMOd> ="0") or to allocate to
communication control switching (when <CMOd> ="2" to "5"), in addition to the above parameters.
For details of adjustment methods by the speed control command and torque control command, refer to the Function
manual for torque control (E6582106).
speed control range: 1:1000
speed accuracy: ±0.02% (50Hz base digital input)
(torque control range: -100% to 100%)
