Schneider Electric ATV630D75N4 75 kW Process Drive

ATV630D75N4 Altivar Process ATV630 drive: what the part number tells you

The ATV630D75N4 is a Schneider Electric Altivar Process ATV630 variable speed drive. The datasheet describes it as: Variable Speed Drive, Altivar Process ATV600, ATV630, 75kW, 100hp, 380 to 480V, IP21, UL type 1. The ATV630 belongs to the Altivar Process ATV600 range, aimed at process and utilities applications, with Ethernet-based Modbus TCP, an integrated EMC filter and STO safety function. Seven Star LLC supplies the ATV630D75N4 in Oman and the GCC as an independent supplier based in Muscat.

Reading the code against the datasheet: the ATV630 prefix is the range; the rating characters match the 75 kW normal duty; 55 kW heavy duty motor power and 145.0 A output current stated in the datasheet; N4 corresponds to the three-phase 400 V class, matching the listed supply of 380 to 480 V. Always confirm any variant by the complete reference, because neighbouring references differ in power class, format or options.

Technical specifications of the ATV630D75N4

How the ATV630D75N4 controls the motor

A frequency converter rectifies the incoming AC supply, stores energy on a DC bus and re-creates a three-phase output of adjustable frequency and voltage. For the ATV630D75N4 the datasheet lists a switching frequency of 2.5 to 8 kHz with derating factor; 2 to 8 kHz adjustable with a nominal value of 2.5 kHz. Higher switching frequency reduces audible motor noise but increases drive losses, which is why the datasheet notes derating at the upper end.

Motor control is selected by software profile. The datasheet lists Constant torque standard for asynchronous motors. Choosing the profile that matches the load is more important than chasing maximum dynamic performance: a centrifugal pump or fan is normally best served by a variable-torque or energy-saving profile, while conveyors and mixers usually need constant-torque behaviour with enough overload margin.

Where the ATV630D75N4 fits in a control system

Control wiring on the ATV630D75N4 follows the I/O count in the datasheet: 8 discrete inputs, 0 discrete outputs, 3 analogue inputs, 2 analogue output(s) and 3 relay output(s). Communication is by Ethernet; Modbus serial; Modbus TCP. Optional modules listed: Slot A communication module, Profibus DP V1; Slot A communication module, PROFINET; Slot A communication module, DeviceNet; Slot A communication module, Modbus TCP/EtherNet/IP; Slot A communication module, CANopen daisy chain RJ45; Slot A communication module, CANopen SUB-D 9; Slot A communication module, CANopen screw terminals; Slot A/slot B digital and analog I/O extension module.

Related parts in the same family are sold by power rating, so siblings of the ATV630D75N4 in the ATV630 series differ mainly in kW, current and enclosure size rather than in functions. At 75 kW this is a large wall-mounted frame of the ATV630 range, for big pumps, fans and compressors.

Selection and ordering checklist for the ATV630D75N4

• Motor nameplate: rated power, rated current, voltage and pole count. Size the drive on motor current, not only on kW; the 145.0 A output current of the ATV630D75N4 is the figure to compare.
• Duty class: confirm whether the load is normal duty or heavy duty, because the datasheet gives separate ratings where both exist.
• Supply: confirm the network matches 380 to 480 V and the frequency, and compare prospective short-circuit current with the 50 kA limit.
• Enclosure: the drive has IP21 IEC 61800-5-1; IP21 IEC 60529; if the cabinet is dusty or wet, plan the enclosure and filtering accordingly.
• Fieldbus: choose the option card, if one is needed, before ordering and note it in the enquiry.
• Safety: the datasheet lists the safety functions fitted; compare them with your machine risk assessment.

Installation, commissioning and maintenance of the ATV630D75N4

Mount the drive in the position the datasheet specifies (vertical, within a small tilt tolerance), leave the ventilation space given in the installation manual and keep the ambient inside the range -15 to 50 °C (without derating). Oman cabinets that sit near the upper limit in summer need either derating, forced ventilation or an air-conditioned electrical room. Dimensions of this unit are 290 mm (W) x 922 mm (H) x 323 mm (D) and its net weight is 58 kg, which helps when checking cabinet layouts.

Commission in a fixed order: verify supply and motor cabling, run the auto-tuning or enter motor data, set ramps and limits, then configure I/O and communication. Keep a saved parameter file of the final configuration; it shortens replacement time if the unit is ever swapped. Periodic work is simple: clean the heat sink and fan path, check terminal tightness, review fault history and replace fans when the maintenance schedule calls for it.

Typical applications of the ATV630D75N4 in Oman and the GCC

Typical uses are process and utility duties: centrifugal pumps, fans, compressors and water-treatment lines running on a wall-mounted IP21 drive. In Oman and across the GCC the drive meets heat, dust and humidity in water-treatment and desalination plants, oil and gas utilities, district cooling, food factories and general manufacturing. For coastal or sandy sites the cabinet design, filtering and temperature margin decide reliability at least as much as the drive itself.
