ACS890 / 400V modules
400 V modular drives for machines and process lines
Build a 400 V-class drive around the motor, load cycle and cabinet. ACS890 separates the control unit from inverter and supply modules, giving machine builders a practical route from a single controlled motor to an engineered common DC bus system.
A module is one part of the complete drive system. An INV / SMM motor inverter takes power from a DC link and supplies controlled AC to the motor. Select the AC-to-DC front end separately, according to whether the machine needs basic rectification, regulated DC voltage or energy regeneration.
The catalog inverter entries below cover 15–500 kW air-cooled modules and 400 / 500 kW liquid-cooled modules. These are catalog PN reference values. A motor with a demanding acceleration, low-speed torque or repeated overload cycle may require a higher current rating than a simple kW comparison suggests.
For a single motor, define the required speed range and torque profile first. For a process line, also define which axes share energy, which follow one another and which must remain independently controlled. ACS890 supports sensorless and encoder-based configurations, motor identification, deep field weakening and flying start.
Machine integration
Choose CU200, CU200-PN or CU200-EC to match the control architecture, then add the required analog, digital and encoder interfaces.
Cooling choice
Air cooling suits a cabinet with a suitable ventilation path. Liquid cooling moves much of the power-stage heat into an engineered cooling circuit; cabinet residual heat still needs attention.
Regenerative duty
A decelerating load does not automatically imply grid regeneration. Select the front end and braking path around returned power, duty cycle and the site supply.
System configuration
Define the power path and supporting equipment.
Functional configuration guide, not an installation wiring diagram. Final protection, connections and component compatibility follow the engineered system documentation.

Read the current correctly: inverter values are motor IN; AFE values are AC / DC currents. LD and HD cells show the catalog power / current references. Continuous ratings use the catalog conditions; where specified, LD is 110% for 1 minute in 5 and HD is 150% for 1 minute in 5. Apply ambient, installation and topology-specific derating. Dimensions are for modules, not complete cabinets.

Control, feedback and power must match.
Include the PLC interface, encoder, operator panel, auxiliary supply, precharge and installation hardware in the quotation. Availability and compatibility depend on the selected module and cabinet configuration.
Application engineering
Match the configuration to the duty.
Conveyors and process machines
Match the current rating to starting torque, conveyor loading and the required stopping cycle.
Coilers and production lines
Review speed / torque following, feedback resolution, field-weakening range and energy sharing between axes.
Pumps, fans and retrofit machinery
Check motor insulation, cable arrangement, restart behavior and whether sensorless operation meets the process requirements.
Product FAQ
Questions about 400v modules.
Is this a complete 400 V drive or an inverter module?
The selection table lists inverter modules. A complete system also needs a compatible control unit, front end or DC supply, precharge, protection and installation components. INOMAX can review a module package or an assembled cabinet.
Can I connect an INV module directly to the AC grid?
No. The inverter power path is DC-link input to controlled AC output. AC grid connection requires the appropriate rectifier or active front end and its supporting components.
Can I select the drive only from motor kW?
Use motor rated current and the complete overload cycle. The table separates PN, continuous IN, light-duty and heavy-duty ratings. Ambient conditions and installation can change the usable current.
Does the 400 V class also cover my 380 V or 415 V supply?
Send the supply voltage and tolerance together with the motor nameplate. The 400 V class label alone does not confirm every operating point; the selected front end, DC link and motor output range must be checked.
Which control and feedback options are available?
The catalog lists CU200-PN for PROFINET and CU200-EC for EtherCAT, with extensions for digital / analog I/O, HTL, TTL, resolver, SinCos and absolute feedback. Select the specific combination needed by the PLC and motor.
Can several 400 V modules operate in parallel?
Eligible inverter and AFE power units support engineered parallel arrangements. Integrated drives and other power topologies have different rules. Current sharing, protection, cooling and the catalog parallel factor must be included in selection.
What are the lead time and warranty?
INOMAX provides a standard two-year warranty, with coverage and start date defined in the order. Production timing is confirmed after the selected models, accessories, quantity and cabinet scope are agreed.
What information is needed for a 400 V quotation?
Provide the supply voltage, motor kW and current, speed range, load / overload cycle, cooling preference, PLC interface, encoder type and required delivery date. Include the existing drive model if this is a retrofit.
