Schneider ATV630D37N4 is a 37kW inverter in the Altivar Process 630 series. The following is a detailed introduction:

Basic parameters

Rated power: 37kW (50hp) at standard load, 30kW (40hp) at heavy load.

Rated current: 74.5A (4kHz) at standard load, 61.5A (4kHz) at heavy load; maximum transient current standard load is 82A (60s), heavy load is 92.3A (60s).

Power supply voltage: Applicable voltage range is 323 - 528VAC, suitable for common three-phase AC power grids such as 380V, 400V, 480V, 500V, etc.

Output frequency: 0.1 - 500Hz.

Dimensions: 673mm (height) × 226mm (width) × 271mm (depth).

Protection level: IP21/UL Type 1.

Features

Control function: supports asynchronous motor and synchronous motor control, with multiple control modes, such as constant torque standard, optimized torque mode, etc. The use of advanced sensor less vector control technology can ensure the best performance and energy efficiency under various working conditions, and can achieve precise speed and torque adjustment.

Communication capability: supports Modbus, Modbus TCP, Ethernet and other communication protocols, and can easily interact and integrate with human-computer interaction devices such as PLC, HMI and other control devices for data exchange and integration, which is convenient for remote monitoring and control.

Safety function: It has STO (safe torque interruption) function, reaching SIL3 safety level, which can quickly cut off the motor torque in an emergency to ensure the safety of personnel and equipment.

Input and output interface: 4 digital inputs (DI1 - DI4, 24VDC, current sinking/current sourcing mode, programmable), 2 digital inputs (DI5 - DI6, 24VDC, current sinking/current sourcing mode, configurable as pulse input), 1 digital input (STOA, 24VDC, current sourcing mode, safe torque off), 1 digital input (STOB, 24VDC, current sourcing mode, safe torque off); 1 digital output (C/O SPDT relay contact R1), 2 digital outputs (normally open relay contacts R2 - R3); 1 analog input (0 - 10VDC/0 - 20mA/4 - 20mA), 2 analog inputs (0 - 10VDC/0 - 20mA/4 - 20mA/PTC/PT100/PT1000/KTY84); 2 analog outputs (0 - 10VDC/0 - 20mA).

Other functions: Built-in C2 class EMC filter, ATEX compliant, can effectively suppress electromagnetic interference, adapt to different working environments; with motor performance and connectivity optimization functions, such as dual-port Ethernet to provide maximum service, network services to ensure operational continuity when the connection is interrupted, network servers and data logging to help reduce downtime through rapid troubleshooting and preventive maintenance; also has asset protection functions to improve production efficiency and reduce downtime.

Application areas

Industrial automation: widely used in various equipment drives in the manufacturing industry, such as conveyor belts, mixers, compressors, etc., can accurately adjust the motor speed according to the production process, improve production efficiency and product quality.

HVAC system: In the field of HVAC, it can be used to control the fan, water pump and other equipment of the air-conditioning unit, automatically adjust the equipment operation speed according to the changes in the indoor and outdoor environment, and achieve energy-saving and comfortable environmental control.

Water treatment industry: It can be applied to the control of water pumps, aeration equipment, mixers, etc. in water treatment plants to achieve precise control of the water treatment process, reduce energy consumption, and improve water quality treatment effects.
