Product Introduction
First, thank you for purchasing the EM590 series frequency converter! The EM590 series and EM580 series frequency converters share identical application scenarios, but the EM590 series offers significantly enhanced usability and superior motor control performance compared to the EM580 series. It delivers notably improved control performance, particularly at higher power ratings.
1) Comprehensive voltage support: Single-phase 220V, three-phase 220V, three-phase 380V, three-phase 480V, three-phase 690V, and three-phase 1140V.
2) Extensive motor compatibility: Supports both three-phase AC induction motors and three-phase AC permanent magnet synchronous motors.
3) Diverse control modes: Includes sensor-based speed control, sensorless vector control, V/F control, and V/F split control.
4) Support for multiple encoder types: Compatible with differential encoders, open-collector encoders, and others.
5) Sensorless vector control algorithm: Sensorless Vector Control (SVC) delivers superior low-speed stability, enhanced low-frequency load capacity, and supports torque control in SVC mode.
6) Powerful external expansion application cards: Multi-function I/O input card, RS485 communication card, injection molding machine card, feeder card, motor overheat card, water supply triple-drive expansion card, etc.
7) The feature-rich EM590 series closed-loop inverters excel in the following functionalities:
EM590 Highlights | describe |
Parameter upload and download | Keyboard parameters upload and download, easy batch debugging. |
Backup and restore user parameters | This function supports customers to save or restore their own set parameters |
User-changed parameter display | Users can view the modified function parameters |
User customized parameter display | Users can customize the function parameters to be displayed |
Chinese keyboard | The entire EM590 series supports Chinese keyboard operation and can be operated without the manual. |
PID water supply pressure intuitive setting | When PID is used for water supply, the set value is no longer a percentage multiplied by the pressure gauge range, but is directly Set the given pressure in MPa, saving calculations and providing a more realistic view. |
Keyboard Knob Quick Set PID given value | After defining the keyboard digital knob as setting the PID given value, there is no need to enter the parameter. The PID setpoint can be set directly using the knob , with a resolution of 0.01 MPa. |
The inverter can be used as a communication host. Without the need for a host computer, Multiple inverters can be linked | In some cases, multiple inverters need to run synchronously. The source command is set as the communication setting. Just set the first inverter as the master. To ensure the multi-frequency inverters are set as slaves, The fixed frequencies are completely consistent or the proportions are consistent. |
Accurate speed tracking | After adapting the corresponding speed detection card, accurate speed tracking can be achieved. |
Instantaneous stop without stopping (applicable to gas stoves Fans and other important occasions) | When the inverter is in a momentary power outage, the voltage of the mains power and power generation conversion suddenly drops, When the voltage returns to normal, it will run automatically (need to be equipped with corresponding expansion card). |
Automatic energy-saving operation | Automatic energy-saving operation can be achieved when light loads such as fans are used |
Motor overheat protection | After selecting the motor overheat expansion card, V3 can receive the motor temperature sensor input. Input ( PT100, PT1000) to realize motor overheat protection. |
Fast current limiting | Avoid frequent overcurrent faults of the inverter and have super strong load capacity. |
1. Output power range: 0.75KW~800KW.
2. Support V/F control and speed sensorless vector control.
3. High starting torque, can output 150% rated torque at 0.5Hz.
4. Overload capacity: G type machine: 150% rated current for 60s, 180% rated current for 3s.
P-type machine: 120% rated current for 60s, 150% rated current for 3s.
5. Automatic voltage regulation output (AVR): When the grid voltage changes, the output voltage can be kept constant.
6. Fast current limiting function: When the load increases, it minimizes overcurrent faults and protects the normal operation of the inverter.
7. Motor grounding protection: Real-time monitoring of whether the motor is grounded and whether the output is equal, to provide all-round protection for the motor.
8. Speed tracking card: can be adapted to the motor speed monitoring card to monitor the motor speed and achieve smooth start.
9. Rich expansion cards: can adapt to a variety of input and output terminal expansion cards, relay output expansion cards, etc.
10. Communication: Stable RS485 communication, adapted to isolated 485 communication card, with strong anti-interference ability.
11. Parameter backup and restore: After the user sets the parameters, they can be backed up and restored with one click.
12. Easy to operate: full Chinese keyboard operation, easy to debug without instructions.
Application areas:
Machine tools, metallurgy, chemical industry, mining machinery, textile machinery, woodworking machinery and other general applications.
