Schneider ATV630D55N4 55KW Altivar Process 630 Variable Frequency Drives VFD

Schneider ATV630D55N4 is a 55kW inverter in the ATV630 series. The following is its related introduction:

Basic parameters

Power supply voltage: The rated power supply voltage range is 380-480VAC, which can adapt to the common three-phase AC power grid voltage.

Power supply frequency: 50-60Hz.

Motor power: 55kW (75hp) at normal load and 45kW (60hp) at heavy load.

Output current: Continuous output current is 106A (2.5kHz) at normal load and 88A (2.5kHz) at heavy load; maximum transient current is 116.6A (60s) at normal load and 132A (60s) at heavy load.

Dimensions: 320mm×852mm×390mm (width×height×depth).

Protection level: IP21, in compliance with IEC 61800-5-1, IEC 60529 standards, can prevent objects larger than 12.5mm from intruding.

Features

Control function: supports asynchronous motor and synchronous motor control. Asynchronous motor control has multiple control modes such as constant torque standard, optimized torque mode, and variable torque standard; synchronous motor control supports permanent magnet motor and synchronous reluctance motor. It has motor slip compensation function, which can be automatically adjusted according to the load, and can also adjust the acceleration and deceleration ramp linearly separately, ranging from 0.01-9999s.

Communication capability: With Ethernet, Modbus serial and Modbus TCP communication port protocols, it can easily exchange and integrate data with the host computer or other devices to achieve remote monitoring and control.

Safety function: With STO (safe torque off) function, it reaches 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: It has 8 digital inputs, 3 relay outputs, and 3 analog inputs/outputs. Digital inputs can be used to receive external control signals, such as start, stop, speed selection, etc.; relay outputs can be used to control external devices, such as contactors, alarms, etc.; analog inputs/outputs can be used to connect sensors, controllers and other devices to achieve precise control and monitoring of the inverter.

Other functions: Integrated 150m EMC filter that complies with EN/IEC 61800-3 C3 class standard, which can effectively suppress electromagnetic interference; with a variety of protection functions, such as overvoltage, overcurrent, overheating, short circuit protection, etc., to ensure the stable operation of the equipment under various working conditions.

Application fields

Industrial field: Widely used in the drive control of various industrial equipment, such as fans, water pumps, compressors, conveyor belts, mixers, etc., can accurately adjust the motor speed according to process requirements, achieve energy saving and optimize the production process.

HVAC system: In the HVAC system, it can be used to control the fan, water pump and other equipment of the air-conditioning unit, automatically adjust the equipment running speed according to the changes in the indoor and outdoor environment, and improve the energy efficiency and comfort of the system.

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