 No-load / light-load operation adjustment
8. Start the motor with no load
(a) Set Pr.11-00 = 1 Auto-tuning for ASR
(b) Start the motor without load, and operates the motor to 1/2 of rated rotor speed
A1. If the start direction is wrong or starting rotation is not smooth (ocA), adjust Pr.11-01
(system inertia). When the Ke parameter (Pr.05-43) is < 25 V, increase Pr.10-31 (I/F
mode, current command) or Pr.10-39, Pr.10-40 (switch the frequency from I/F mode to
PM Sensorless mode).
A2. If the motor starts up with a reverse direction, but operates with a correct direction, adjust
Pr.10-52 (injection magnitude) when using High frequency injection to detect the PM initial
rotor position (Pr.10-53 = 2); increase Pr.10-42 (initial angle detection pulse value) to
improve the accuracy of angle detection when using Pulse injection to detect the PM
initial rotor position (Pr.10-53 = 3).
9. Acceleration test with no load / light load
A3. Accelerate the motor to the rated frequency, and check if it operates stably.
a. If the motor output frequency presents steady state speed wave, increase Pr.11-04
(ASR2 high-speed bandwidth) or Pr.11-01 (per-unit of system inertia).
b. If the motor output frequency presents large fluctuations or diverges, increase Pr.10-55
(magnetic flux linkage estimate high-speed gain) or decrease Pr.10-56 (Kp of phase-
locked loop).
A4. Accelerate the motor to the maximum frequency, and check if it operates stably.
If the motor stalls at the maximum operation speed, increase Pr.10-55 (magnetic flux
linkage estimate high-speed gain) and Pr.00-17 (carrier frequency), or decrease Pr.10-56
(Kp of phase-locked loop).
Setting curve for speed regulator (ASR) and related parameters:
Parameter Description Default
Pr.11-00 System control 0
Pr.11-01 Per-unit of system inertia 256
Pr.11-02 ASR1 / ASR2 switch frequency (set the switch frequency > Pr.10-39) 7 Hz
Pr.11-03 ASR1 low-speed bandwidth 10 Hz
Pr.11-04 ASR2 high-speed bandwidth 10 Hz
Pr.11-05 Zero-speed bandwidth 10 Hz
