ABB ACS800-01/U1 drive unit

ABB ACS800-01/U1 drive unit

Only qualified electrical engineers are permitted to install and maintain drive units.

It is strictly prohibited to install or repair transmission units, motor cables or motors while they are powered on. After cutting off the input power supply, it should arrive

Wait for 5 minutes less until the capacitor in the intermediate circuit is completely discharged before proceeding with the operation. Before starting the operation, one should also

Use a multimeter (with an impedance of at least 1 megohm) to measure the voltage between terminals UDC+ and UDC- and be sure

The transmission unit has discharged completely.

It is strictly prohibited to operate the control cable when the transmission unit or external control circuit is powered on. Even if the main power supply of ACS 800 is cut off

There may still be dangerous voltages introduced by external control circuits inside electricity.

All insulation tests must be conducted with the cable connection disconnected.

When reconnecting the cables, make sure the phase sequence is correct.

Note

Regardless of whether the motor is running or not, as long as the input power supply of the ACS 800 drive is connected, the motor cable terminals will remain

At dangerous high voltage.

The brake control terminals (UDC+, UDC-, R+ and R- terminals) carry dangerous DC high voltages (greater than 500)

V).

The relay output terminals RO1 to RO3 are dangerous when connected to 115V or 220V (230V) voltage

High voltage.

Printed circuit board

The transmission unit includes the following standard printed circuit boards:

• Main circuit board (RINT);

• Motor control and I/O control board (RMIO);

When EMC equipment is selected, there should be an EMC filter board (RRFC); otherwise, it should be a varistor board (RVAR).

• Control panel (CDP 312R).

• Copper busbar (RBUB) in the shape specification R6.

Motor control

The motor control mode can be selected as Direct Torque control (DTC) or scalar control.
