GE C11, AF-300 manual Trial Run, 3-1 Running command

3-3 Trial Run

The motor rotates when a frequency value and running command are input from the keypad panel or external signal terminal. Refer to Table 3-3-1.

Use a low frequency (about 5Hz) for trial runs

A frequency can be set using the built-in frequency setting POT (VR) , and forward/stop can be performed using the keypad panel with the functions set in the factory.

Check the following items:

a)Rotation direction

b)Whether rotation is smooth (whether there is a motor buzzing noise or abnormal vibration)

c)Whether acceleration and deceleration are smooth

d)Whether the drive cooling fan is rotating (1.5kW or more)

If no abnormality is detected, check the item again by increasing the frequency.

Even if the output from the drive is stopped, you will be get an electric shock when you touch the main circuit terminals such as drive output terminals U, V and W if the voltage is supplied to the main power supply input terminal.

The smoothing capacitor in the drive has been charged when the power is turned off and it is not dis- charged immediately. Before touching the electric circuit, wait until at least five minutes have elapsed after power-off and the charge lump is off, indicating the voltage is already low.

After checking normality in the above trial run, start operation.
