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.
- 400 V AC catalog class; code -4 inverter modules
- Air-cooled R frames and liquid-cooled L7 modules
- Current-based selection with light- and heavy-duty ratings
Coordinate the motor group and manage energy across the machine. ACS890 combines a modular DC-link architecture with torque, speed and position-following functions for engineered multi-drive systems.
- Common DC bus with application-specific supply and motor branches
- Torque sharing, speed following and position / phase following
- 1–4 coordinated motors is separate from the parallel power-unit count
Return usable braking energy through an engineered active front end. ACS890 ALM / AFE modules regulate the DC link and control grid current as part of a coordinated drive system.
- Bidirectional energy flow between the DC link and AC supply
- Catalog architecture: CU + ALM + SLC + CHG + VSM
- Motor-side inverter, front end and braking duty selected separately
Choose the cooling arrangement that fits the installation, then confirm the electrical rating. ACS890 offers air- and liquid-cooled platforms with different frame, voltage and current coverage.
- Compare cabinet ventilation with an engineered liquid-cooling loop
- Air / liquid choices for listed 400 V and 700 V AC classes
- Liquid-cooled three-level modules for 900 V and 1140 V classes
Scale the power stage around the required motor current and operating duty. ACS890 supports 1–16 eligible parallel inverter or AFE power units, with configuration-specific rules for current sharing, protection and cooling.
- 1–16 eligible parallel INV / AFE power units
- Current-based sizing, including the catalog 0.97 parallel factor
- Up to 4 MW per cabinet for the specified 3.3 kV liquid-cooled three-level configuration
The ACS890 1140 V liquid-cooled three-level platform is designed for engineered high-power motor systems. Select T-frame inverter modules together with the correct front end, cooling loop, precharge and control equipment.
- 1140 V AC class / code -11 three-level inverter modules
- Listed module PN values from 500 to 1500 kW
- CHG20 precharge and frame-specific installation options
Configure ACS890 for 690 V industrial motor systems using the catalog’s 700 V AC class and code -7 module families. Combine the selected inverter, front end, control and cooling arrangement around the duty of the machine.
- 700 V AC catalog class / code -7 for 690 V applications
- Air-cooled modules to 560 kW; liquid-cooled modules to 800 kW in the listed selection
- Common DC bus and regenerative configurations by project
