hazard of electric shock, explosion, or arc flash
Before operating the ATV680 process drive:
Failure to follow these instructions will result in death or serious injury.
|
Voltage Supply and Auxiliary Voltage
-
All drive systems are equipped with a control transformer matching the mains voltage and the required power.
-
The DC supply units generate 48 Vdc for the internal power fans, the fans in the drive enclosure doors, and a 24 Vdc auxiliary voltage.
-
By default all control components are supplied by the 115 Vac control transformer.
Undervoltage
In the event of short-time mains voltage sag, operation is possible under the following conditions:
Undervoltage Behavior
Mains Undervoltage | Restriction |
---|---|
-10% of nominal voltage | Starting the drive and continuous operation* |
-15% of nominal voltage | Starting the drive and operation* for 10 s per 100 s |
-20% of nominal voltage | Operation* for less than 1 s |
-30% of nominal voltage | Operation* for less than 0.5 s |
-50% of nominal voltage | Operation* for less than 0.2 s |
Mains Current Harmonics / Mains Voltage Distortion
The ATV680 Low Harmonic Process Drive is equipped with an active mains supply converter, so typical harmonic currents associated with six-pulse diode bridge topologies are not generated on the mains side of the equipment.
The 3-level technology converter generates a total harmonic distortion factor TDD(i) (total demand distortion) of around 2% and meets the requirements of IEEE 519-2015 TDD(i) < 5%. This performance level is possible when operating in either motoring or generating modes.
In addition, the active converter always operates at unity power (> 30% Pn) and helps to reduce the mains current as a result.
Current Harmonics shows typical values of the individual current harmonics at operation with the ATV680 Low Harmonic Process Drives.

Read and understand the instructions before performing
any procedure in this section.
Failure to follow these instructions will result in death or serious injury.

The enclosed drives have a built-in EMC/RFI filter board. As a result, they exhibit leakage current to ground. If the leakage current creates compatibility problems with your installation, you can reduce the leakage current by positioning the setting bolts as shown in Configuration. In this layout, the product does not meet the EMC requirements according to standard IEC 61800-3.
Configuration
-
Remove all power from the enclosed drive.
-
Turn the circuit breaker and handle assembly to the Off position and open the enclosure door.
-
Test for the absence of voltage.
NOTE: Verify that the voltage tester is functioning properly before and after testing for the absence of voltage. -
Locate the EMC/RFI filter board. It is typically located in the lower right corner of the enclosure. See Settings for 125–700 hp HD, 150–900 hp ND, 460 V Enclosed Drives.
-
Remove two nuts and remove the clear plastic cover. See Settings for 125–700 hp HD, 150–900 hp ND, 460 V Enclosed Drives.
-
For operation on a system that is not IT or corner-grounded
, position the bolt and washer as shown in Settings for 125–700 hp HD, 150–900 hp ND, 460 V Enclosed Drives, detail 1. Tighten the bolt to 49 lb-in. (5.5 N•m).
NOTE: Take care when you remove the bolt, as the EMC/RFI filter board can shift. -
For operation on an IT or corner-grounded system
, position the bolt and washer as shown in Settings for 125–700 hp HD, 150–900 hp ND, 460 V Enclosed Drives, detail 2. Tighten the bolt to 49 lb-in. (5.5 N•m).
-
Replace the clear plastic cover. Reinstall the two nuts and tighten them to 49 lb-in. (5.5 N•m).
-
Close all doors and restore power to the enclosed drive.

It includes a number of possible power circuit additions including selection of harmonic and transient mitigation methods. Additional space is provided for engineered to order options and field installable equipment.
Power Circuit Y (Mod Y10): With Integral Full-Voltage Bypass
The bypass power circuit provides a coordinated drive and circuit breaker package and the flexibility and security of a full-voltage bypass motor drive that is available at any time. The Zelio Smart Relay coordinates the power converter's output contactor and bypass contactor. See Appendix A - Zelio™ Smart Relay Ladder Logic for more information. A number of possible power circuit additions, including selection of harmonic and transient mitigation methods and options like the field service disconnect and line isolation contactor, are available in this power circuit configuration. This provides even better reliability and serviceability. Additional space is provided for engineered to order options and field installable equipment.
The integral full-voltage bypass starter includes a Class 10 bimetallic or solid-state overload relay.
