Drive at a glance
The ATV930U40M3 is a current-production Altivar Process drive sized for a 4.0 kW motor in normal duty or 3.0 kW in heavy duty, running on 200-240 V three-phase supply. Standard fit includes a braking chopper and an integrated EMC filter. IP21 enclosure with UL Type 1 rating covers most indoor panel applications.
Ratings and capacity
Continuous output current is 18.7 A at 4 kHz for normal duty, dropping to 13.7 A for heavy-duty cycles. Motor power is 4.0 kW normal / 3.0 kW heavy, which means a standard 4 kW induction motor on a pump or fan runs comfortably; the heavy-duty rating covers constant-torque loads like conveyors. Supply voltage tolerance is 200-240 V ±10%, and overvoltage category III holds up on distribution panels. Built-in PID regulator allows direct process-loop control without an external controller. The braking chopper is rated for the drive's continuous output, so vertical loads or quick stops need only an external resistor – no chopper module to add later. Communication comes standard with Modbus serial, Modbus TCP, and EtherNet/IP at 10/100 Mbits, plus a slot for optional Profibus DP, PROFINET, DeviceNet, EtherCAT, or CANopen modules. Serial link runs at 9600, 19200 bps; factory default is 19200 8N1.
