ABB LC-608 Communication gateway module

After expire of the pulse current phase, the current is automatically reduced to the continuous current, adjustable at P5. For adjusting P5, always turn slowly. After a short time the new continuos current flows. Adjustment becomes essentially easier when instead of the motor, three wye-connected reactors are connected to the motor connections. The reactors should have a minimum load inductance and a saturation current, that exceeds the maximum current of the amplifier.

Setting the Maximum Motor Speed 

The amplifier is set ex factory to a motor speed of max. = 3000 with 10V input voltage for our motors. In order to reduce the maximum motor speed, turn the input potentiometer to the left, to increase the motor speed turn it to the right.The offset adjustment has to be carried out in a warm operating status of the device. Define the set value zero (short-circuit the input). Adjust motor drift by setting P4 to zero.
