How To Control The Drive Through The I/O Interface - ABB ACS150 series User Manual

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.
If you need to change the direction of rotation, check that parameter
1003 DIRECTION 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.
Text FWD starts flashing fast and stops after the setpoint is reached.
Regulate the drive output frequency (motor speed) by adjusting the
voltage or current of the analog input AI(1).
CHANGING THE DIRECTION OF THE MOTOR ROTATION
Reverse direction: Switch digital input DI2 on.
Forward direction: Switch digital input DI2 off.
Switch digital input DI1 off.
The motor stops and text FWD starts flashing slowly.
