 Adjustment for operation with no load / light load
9. No-load trial run
Set the frequency command to 10 Hz to proceed the encoder running test:
A1. If the motor starts in a reverse direction.
If the motor starts in a reverse direction, set the encoder input type Pr. 10-02 = 2 (A-phase
and B-phase are pulse inputs, forward direction if B-phase leads A-phase by 90 degrees.)
A2. Observe if a PGFx error is displayed on the keypad, or the motor runs in an abnormal
speed.
If the PGFx error is displayed or the motor runs in an abnormal speed, refer to Chapter 14
“Fault Codes and Descriptions” or the following table for PGFx error type and further
treatment.
PGF Error (code) Description Solution
PGF1 (42) PG feedback error Check parameter setting of Pr.10-00–10-02
PGF2 (43) PG feedback loss Check the wiring of encoder and PG card
PGF3 (44) PG feedback stall Check the wiring of encoder and PG card
PGF4 (45) PG slip error
Check the pulse setting of Pr.10-01
Check the wiring of encoder and PG card
PGF5 (65) PG hardware error
Check if the PG card is installed on the
correct slot position
Check the setting parameter of the encoder
10. No-load / light load running test
a. Set the speed regulator (ASR) as Pr.11-00=1, and set the ASR gain as auto-tuning.
b. Start the motor with no load / light load and proceed acceleration / deceleration test.
B1. Accelerate to the rated frequency and observe if the motor runs stably.
- If the output rotor speed cannot follow the acceleration time, increase Pr.11-04 (ASR2
high-speed bandwidth) or Pr.11-03 (ASR1 low-speed bandwidth).
- If a high-frequency oscillation occurs in the output frequency, decrease Pr.11-04 (ASR2
high-speed bandwidth) or Pr.11-03 (ASR1 low-speed bandwidth).
B2. Accelerate the motor to the maximum frequency and observe if it runs stably.
If an oscillation occurs or motor stalls at maximum rotor speed during operation, increase
Pr.11-04 (ASR2 high-speed bandwidth) or Pr.00-17 (Carrier frequency).
