FC 300 Design Guide
Set-up example
In this example, a permanent magnet (PM) motor is used with resolver as speed feedback.
A PM motor must usually operate in flux mode.
Wiring:
The max cable length is 490 ft [150 m] when a twisted-pair cable is used.
NOTE
The resolver cable shielding must be correctly connected to the de-coupling plate and
connected to the chassis (ground) on the motor side.
NOTE
Always use shielded motor cables and brake chopper cables.
Adjust the following parameters:
Par. 1-00 Configuration Mode
Par. 1-01 Motor Control Principle
Par. 1-10 Motor Construction
Par. 1-24 Motor Current
Par. 1-25 Motor Nominal Speed
Par. 1-26 Motor Cont. Rated Torque
AMA is not possible on PM motors
Par. 1-30 Stator Resistance
Par. 1-37 d-axis inductance (Ld)
Par. 1-39 Motor Poles
Par. 1-40 Back EMF at 1000 RPM
Par. 1-41 Motor Angle Offset
Par. 17-50 Poles
Par. 17-51 Input Voltage
Par. 17-52 Input Frequency
Par. 17-53 Transformation Ratio
Par. 17-60 Feedback Direction
Par. 17-61 Feedback Signal Monitoring
