How to control the drive through the I/O interface

The table below instructs how to operate the drive through the digital and analog
inputs when:
• the motor start-up is performed, and
• the default (standard) parameter settings are valid.
Displays of the Basic Control Panel are shown as an example.
If you need to change the direction of rotation, check that parameter
1003 is set to 3 (REQUEST).
Ensure that the control connections are wired according to the
connection diagram given for the ABB Standard macro.
Ensure that the drive is in remote control. Press key
between remote and local control.
STARTING AND CONTROLLING THE SPEED OF THE MOTOR
Start by switching digital input DI1 on.
Basic Control Panel: Text FWD starts flashing fast and stops after the
setpoint is reached
Assistant Control Panel: The arrow starts rotating. It is dotted until the
setpoint is reached.
Regulate the drive output frequency (motor speed) by adjusting the
voltage of analog input AI1.
CHANGING THE DIRECTION OF ROTATION OF THE MOTOR
Reverse direction: Switch digital input DI2 on.
Forward direction: Switch digital input DI2 off.
