GENERAL APPLICATIONS PERFORMED WITH WD770
ULTIMATE PERFORMANCE POWERFUL HARDWARE
Harmonic Filter
Built-in DC chokes reduce harmonic distortion in the grid in accordance with IEC 61000-3-12 standards. They also increase the lifetime of the DC link capacitors and therefore the efficiency of the drive.
EMC Filter
WellDrive WD770 products have built-in EMC/RFI filters as standard. You can specify the standard or optional EMC filter type in accordance with the following standards.
LCD Keypad
WellDrive offers great convenience in your commissioning processes with its easy-to-carry Graphic LCD Display Operator Panel, which includes multiple language options, a 5-line wide screen, Real-time clock, and many other features.
Independent Cooling
The WD770 can be expanded with optional I/O and various communication cards. This provides flexible compatibility for your system.
Coated PCBs
All electronic components within WellDrive are protected by varnish coating in accordance with IEC 60721-3-3 standards.
Expansion Modules
The WD770 can be expanded with optional I/O and various communication cards. This provides flexible compatibility for your system.
ADVANCED FEATURES FLEXIBLE SOFTWARE
In the event of a fire, it prevents the drive from ignoring all warning and error signals and taking itself into self-protection, thus ensuring continuous operation of the fan or pump.
It provides precise control of your process values such as Temperature, Pressure, Flow, Humidity without the need for an external controller. It also provides lower and upper limit level control.
It monitors the rotational speed of the motor to reduce the incoming pulse and improve restart efficiency and ensures that the motor resumes at the same speed at restart. In the event of a momentary power failure, the drive will continue to run automatically if this function and the start signal are active.
It ensures that the motor stops when there is no demand and saves energy. When the demand increases and the set values are reached, the motor is automatically restarted.
The driver provides DC current during power interruptions to increase the motor’s surface temperature and prevent motor failure caused by condensed water.
Thanks to the Auto-Tune feature, it reaches stable operation in your process quickly and easily by automatically optimizing the PID settings.
It allows a motor to be started from the mains when the failed drive cannot be used or when it is necessary to continue running at full speed.
One of the fans sharing the same duct is in a regeneration state under the influence of the others. The drive automatically keeps the output frequency under control to prevent over-voltage alarm and ensure stable operation of the machine.
Optimizes output power, ensuring optimum performance and lowest losses for low dynamic loads.
It can detect belt breakage in applications such as fans and compressors and can use this to stop the motor or send a warning signal.
The WD770 can control standard induction motors (IM), permanent magnet motors (PM), asynchronous and synchronous reluctance motors (SynRM) with high efficiency.
The WD770 supports AI/AO temperature measurement function for PT100, and KTY84 sensors. It also enables flexible operations such as differential pressure operations, along with arithmetic operations between analog inputs, in processes such as PID.
Up to 8 pumps can control multiple pumps. Real time clock support, synchronization and roaming master features are available.
In situations where it's necessary to fill pipes in a controlled manner, this feature allows pumps to start and stop slowly and smoothly. This helps prevent water-hammering, as well as damage to pipes and heads.
By continuously monitoring the pump operation, it detects dry running or leakage and prevents mechanical damage to the pump.
When the ambient temperature drops below a set threshold, the motor starts automatically to prevent the water from freezing and thus protect the pump.
It detects blockages that may occur in the pumps and ensures cleaning by systematically running forward and backward. This not only saves on mechanical maintenance but also keeps the pump’s efficiency at its highest level.
The WD770 has special protection functions for designated areas of use, safeguarding your motor, drive, and process.
When used with the LCD Panel, the driver can be programmed according to the time and date information, and malfunctions can be monitored.
It records the instantaneous operating values at the time of failure and enables analysis to uncover the causes and solutions.
It is free software with a user-friendly interface that allows you to easily program the WellDrive product family from your computer and access many of its functions.
In addition to Modbus RTU communication protocol, it provides full compatibility with your systems with various options such as BACnet, ProfiNET, and ProfiBus.
