YASKAWA U1000 - Test Run Checklist

n
During Operation
Check the following items during operation:
•
The motor should rotate smoothly (i.e., no abnormal noise or oscillation).
•
The motor should accelerate and decelerate smoothly.
u
Test Run with the Load Connected
After performing a no-load test run, connect the motor and proceed to run the motor and load together.
n
Checklist Before Operation
•
The motor should rotate in the proper direction.
• The motor should accelerate and decelerate smoothly.
n
Operating the Motor under Loaded Conditions
Test run the application similarly to the no-load test procedure when connecting the machinery to the motor.
• Monitor U1-03 for overcurrent during operation.
• If the application permits running the load in the reverse direction, change the motor direction and the frequency reference
while watching for abnormal motor oscillation or vibration.
• Correct any problems that occur with hunting, oscillation, and other control-related issues.

Test Run Checklist
Review the checklist before performing a test run. Check each item that applies.
No. Checklist Page
1 Thoroughly read the manual before performing a test run. –
2 Turn the power on. –
Check the items that correspond to the control mode being used.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before energizing
the drive.
Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary
closure on terminal S1 may cause the drive to start.

V/f Control (A1-02 = 0) and V/f Control with PG (A1-02 = 1)
3 Select the best V/f pattern according to the application and motor characteristics. –
4 Perform Rotational Auto-Tuning for V/f Control if using Energy Saving functions. –
V/f Control with PG (A1-02 = 1)
5 Set up the PG feedback parameters correctly and make sure the encoder pulse counting direction is correct. –
6 Set the proportional gain for ASR speed control to C5-01 and the integral time to C5-02. –
Open Loop Vector Control (A1-02 = 2) or Closed Loop Vector Control (A1-02 = 3)
7 Decouple motor shafts and machines when performing Rotational Auto-Tuning. –
8 Set the Auto-Tuning mode to T1-01 (0 for Rotational Auto-Tuning). –
9
Enter the following data according to the information listed on the motor nameplate:
• Motor rated power to T1-02 (kW)
•
Motor rated voltage to T1-03 (V)
• Motor rated current to T1-04 (A)
• Motor base frequency to T1-05 (Hz)
• Number of motor poles to T1-06
• Motor base speed to T1-07 (r/min)
–
Closed Loop Vector Control (A1-02 = 3)
10 Set F1-01 and F1-05. –
11 Set ASR proportional gain to C5-01 and ASR integral time to C5-02. Perform ASR Tuning if possible. –
