The ATV630D11N4SW is a standard-variant Altivar Process drive rated 11 kW (15 hp) for normal duty and 7.5 kW (10 hp) for heavy duty, fed from a 380-480 V three-phase supply. The normal-duty current is 23.5 A continuous at 4 kHz carrier, which is the figure to use when sizing the input breaker and motor cable for a centrifugal pump or fan load. Heavy-duty current drops to 16.5 A at 4 kHz — that is the rating for constant-torque loads like a screw conveyor or extruder where the drive must deliver full torque down to zero speed. The integrated EMC filter is rated for 50 m of motor cable at category C2 (first environment, residential/commercial) and 150 m at category C3 (second environment, industrial). That means for most industrial panel builds you can run 150 m of shielded cable without an external filter, which saves panel space and installation cost. The filter is built in, not an add-on option card. This is the safety function that removes torque-producing power from the motor without disconnecting the mains — it is the standard interface for integrating the drive into a safety circuit with a safety PLC or safety relay. The STO input is dual-channel and must be wired to a certified safety output.
IP21 protection means the drive is drip-proof but not hose-down rated — it belongs in a clean, dry indoor enclosure. The wall-mount format requires vertical orientation within ±10° and clearance around the forced-convection cooling fan that moves 103 m³/h of air. Pollution degree 2 (non-conductive, occasional condensation) matches typical control-room or electrical-room conditions. For a drive installed at 2000 m, budget 10% less continuous current — the heavy-duty figure drops from 16.5 A to about 14.9 A. The ambient temperature range is not explicitly stated in the spec table, but the forced-convection cooling and 56 dB noise level suggest a standard 40-50 °C ambient ceiling typical for this class. The drive carries UL 508C listing and UL Type 1 enclosure rating, so it can be installed in a UL-compliant panel without an additional enclosure for indoor use.
I/O, communications, and expansion slots
Eight discrete inputs are onboard, with DI7 and DI8 programmable as pulse inputs up to 30 kHz — useful for connecting an encoder or flowmeter directly without an external pulse divider. The adjustable PID regulator is built in, so for a simple pressure or flow control loop you do not need an external process controller; set the setpoint and gains in the drive parameters. Onboard communication ports are Modbus TCP, Ethernet, and Modbus serial — the standard suite for most plant-floor networks. Slot A accepts a fieldbus option card for Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, CANopen (three connector variants), or Ethernet Powerlink. Slot A and slot B also accept digital/analog I/O extension or output relay extension modules. This means the drive can be ordered as a base unit and the communication interface added later without changing the drive order code. The drive is compatible with both asynchronous (induction) and synchronous (PM) motors, so it can be used with a retrofit of an existing induction motor or a new high-efficiency PM motor. Output frequency range is 0.1 to 500 Hz, covering standard 50/60 Hz motors and high-speed spindles up to 30,000 rpm (for a 4-pole motor).
The standard variant means this is the base configurable drive, not a pre-configured or application-specific version. If the BOM calls for a specific fieldbus or I/O configuration, the option card is ordered separately and installed in slot A or slot B. No pin-compatible direct alternative exists within the ATV630 family — the order code defines the power stage and enclosure size; a different power rating requires a different order code.
