No-Load Operation Test Run
This section explains how to operate the drive with the motor decoupled from the load during a test run.
n Before Starting the Motor
Check the following items before operation:
• Ensure the area around the motor is safe.
• Ensure external emergency stop circuitry is working properly and other safety precautions have been taken.
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. Refer to the Z1000 AC Drive
User Manual TOEP C710616 45 section on Test Run with Load Connected for details.

Test Run Checklist
Review the checklist before performing a test run. Check each item that applies.
No.
1 Thoroughly read the manual before performing a test run.
2 Turn the power on.
3 Set the voltage for the power supply to E1-01.
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.
No.
V/f Control (A1-02 = 0)
4 Select the best V/f pattern according to the application and motor characteristics.
5 Perform Rotational Auto-Tuning for V/f Control if using Energy Saving functions.
Open Loop Vector Control for PM (A1-02 = 5)
6 Perform Auto-Tuning as described.
