Pick the EC590 for general machinery that needs dependable V/F and sensorless vector control — pumps, fans, compressors, textile and packaging lines. Pick the EC6000 when the application needs torque control, closed-loop speed stability, through-wall mounting or expansion cards. Both platforms cover the 0.75–315 kW range with English documentation and Modbus integration.
What are the main differences?
| Selection factor | EC590 | EC6000 |
|---|---|---|
| Positioning | General-purpose machinery, cost-sensitive projects | Demanding production lines, higher dynamics |
| Control modes | V/F and sensorless vector (SVC) | V/F, open-loop and closed-loop vector |
| Speed & torque | Speed control with sensorless accuracy | Speed and torque control, closed-loop option |
| Motor types | Induction and PM synchronous | Induction and synchronous |
| Mounting | Book-type, side-by-side installation | Through-wall mounting supported |
| Integration | Built-in RS-485 / Modbus RTU | Modbus plus expansion options |
| Power range | 0.75–315 kW | Part of the 0.75–315 kW platform range |
Which applications fit each drive?
The EC590 general-purpose vector VFD is the workhorse for machinery where stable speed and controlled acceleration matter more than closed-loop precision: pumps, fans and HVAC, compressors, textile machines and packaging equipment. One hardware platform covers both induction and PM synchronous motors, which simplifies spares for panel builders.
The EC6000 high-performance VFD suits lines that need controlled torque at low speed, closed-loop speed stability or richer integration — cranes and hoists, extruders and wire drawing, machine tools and multi-axis production equipment. Expansion options and through-wall mounting make it easier to build into demanding cabinets; see the application families on our applications overview.
Three questions to decide
- Does the axis need torque control or closed-loop speed stability? If yes, choose the EC6000.
- Do you need through-wall mounting or option cards for feedback and communication? If yes, choose the EC6000.
- Otherwise choose the EC590 — you keep the budget and cabinet space down while retaining sensorless vector performance.
Mixed fleets are common and perfectly reasonable: both platforms share English documentation and Modbus connectivity, so many panel builders run the EC590 on utilities — pumps, fans, compressors — and reserve the EC6000 for the demanding axes.

FAQ
Does the EC6000 support encoder feedback?
Yes. Closed-loop vector control is a core EC6000 mode, with expansion options for feedback devices. Tell us your encoder type and speed-accuracy target and we will confirm the configuration before you order.
Which drive is right for a 90 kW water pump?
For a standard centrifugal pump, the EC590’s sensorless vector control is normally sufficient. Send the pump motor’s full-load current and duty cycle and we will confirm the frame — see our guide on how to size a VFD for the data we need.
Do both drives support Modbus?
Yes. The EC590 includes built-in RS-485 / Modbus RTU; the EC6000 offers Modbus plus expansion options for wider system integration.
