● Set Pr.05-00 Motor Parameter Auto-tuning =13 (High frequency stall test for PM synchronous AC motor) and
press RUN.
● When you finish tuning, the following parameters are available:
– Pr.05-39: Stator resistance
– Pr.05-40: Permanent magnet synchronous AC motor Ld
– Pr.05-41: Permanent magnet synchronous AC motor lq
– Pr.05-43: (V / 1000 rpm), the Ke parameter of PM synchronous AC motor (you can calculate this
automatically according to power, current, and speed of the motor).
● Set the speed control mode: Pr.00-10 Control Mode = 0, Pr.00-11 Speed Control Mode = 2 SVC.
● Cycle the power after you finish tuning.
● The ratio of the PMSVC control mode is 1:20.
● When the PMSVC control mode is under 1/20th of the rated speed, the load bearing capacity is 100% of the
motor rated torque.
● PMSVC control mode is not applicable to zero speed control.
● The start-up load and the load bearing capacity of the forward/reverse running in PMSVC control mode equal to
100% of the motor rated torque.
