Schneider Electric ATV630D18N4

For demanding industrial tasks, turn to the high-performance drive from Schneider Electric, the Altivar Process 630 VSD (ATV630D18N4). This variable speed drive is a part of the well-respected Altivar Process ATV600 family. Because of its reliable control of both synchronous and asynchronous motors, it is widely used in a wide range of industrial applications.

Technical Specifications:

Voltages ranging from 380 to 480 V are compatible with the ATV630D18N4. The drive's versatility stems from its ability to work with both synchronous and asynchronous motors. Normal duty uses 18.5 kW of motor power, whereas heavy load uses 15 kW. The maximum rating is 25 horsepower for ordinary duty and 20 horsepower for heavy load.

With its forced convection cooling mechanism, the device can be kept at the perfect working temperature. It features an integrated EMC filter and meets with EN/IEC 61800-3 regulations. The ATV630D18N4 has a continuous current output of 39.2 A at 4 kHz under normal operation and 31.7 A under heavy duty.

Its tiny profile € ”211 mm wide, 546 mm tall, and 232 mm deep € ”makes the small drive ideal for wall hanging. There are 14.2 kg. The IP21 shell protects the drive from harsh objects and water. Noise requirements are met by maintaining operating noise below 59.5 dB.

Protection and Safety:

The ATV630D18N4 has various safety features, including SIL 3 safe torque off (STO). The motor and drive are also protected from outside heat. Integrated output phase and earth fault overcurrent protection. The drive prevents motor phase breakdowns and short circuits for safe operation.

The drive has line supply overvoltage and undervoltage protection for operational safety. Overload protection protects output voltage. Drive braking uses DC injection to stop the motor safely. Drive characteristics include customizable accelerating and deceleration ramps and automated motor slip correction.

Connectivity and Interface:

In the ATV630D18N4 software, two analog outputs and three inputs can be set for current and voltage. Analog inputs and outputs allow signals from 0 to 10 V DC and 20 mA, respectively. Each of the eight driving inputs can accept positive or negative logic.

Fault signaling and sequence control use three relay outputs, one for 250 V AC and 30 V DC. RJ45 connectors link the drive to Ethernet/Modbus TCP and serial networks. Replaceable screw connectors simplify control terminal installation and maintenance.

Application and Performance:

The ATV630D18N4 has HVAC, food and drink, mining, oil and gas, and water and wastewater management applications. Its versatility comes from its compatibility with many pump types and centrifugal and screw compressors. The drive's nominal switching frequency is 4 kHz, adjustable between 2 and 12 kHz.

Drive performance curves derate with temperature and mounting type. The highest transient current capacity for normal duty is 43.1 A and for heavy duty 47.6 A. The drive's 500 Hz maximum output frequency allows accurate motor control over a wide speed range.
