Sequence of Operation
1. Carefully read the safety instructions in the front of this manual and above and follow
them.
2. After the installation, make sure that:
● both the drive and the motor are grounded.
● the power supply and motor cables comply with the requirements given in
Chapter 3.
● the control cables are located as far as possible from the power cables (see
Chapter 3) and the shields of the shielded cables are connected to protective ground.
The wires may not touch the electrical components of the drive.
● For option boards only: make sure that the common ends of digital input groups are
connected to +24V or ground of the I/O terminal or the external supply.
3. Check the quality and quantity of cooling air. (See Chapter 2, Mounting Space
Dimensions.)
4. Check the inside of the drive for condensation.
5. Check that all Start/Stop switches connected to the I/O terminals are in Stop position.
6. Connect the drive to power supply.
7. Set the parameters of group 1 according to the requirements of your application (see
application manual). At least the following parameters should be set:
● motor nominal voltage
● motor nominal frequency
● motor nominal speed
● motor nominal current
You will find the values needed for the parameters on the motor nameplate.
Note: You can also run the Start-Up Wizard. See Page 6-4.
8. Perform run test without motor.
Perform either Test A or Test B:
Test A — Controls from the I/O terminals:
● Turn the Start/Stop switch to ON position.
