Powerful Functions of the ZPS-7000 Series
● Virtual IO Function
5 groups of virtual DI/DO can be set. The status of virtual DI terminals can be directly assigned via function codes or bound to corresponding virtual DO functions.
● Flexible and Practical Analog Input/Output Ports
Each analog input (AI1~AI3) can have its curve set at 4 points individually for more flexible use. The linear curves of AI1~AI3 can be calibrated at the factory or by the user on-site, achieving an accuracy of 20mV after calibration. The AO can have its zero drift and gain calibrated at the factory or by the user on-site, achieving an accuracy of 20mV after calibration. AI1~AI3 can all be used as digital inputs (DI). AI3 is an isolated input port that can be used as a PT100, PT1000, or 10V input.
● Fast Current Limiting Function
The fast current limiting function prevents the drive from frequent overcurrent alarms. When the current exceeds the current protection point, this function quickly limits the current to within the protection point, thereby protecting equipment safety and avoiding overcurrent alarms caused by sudden load changes or interference.
● Momentary Power Loss Ride-Through
This function prevents the drive from stopping during a momentary power loss. In the event of an instantaneous power failure or sudden voltage drop, the drive reduces the output speed, using energy feedback from the load to compensate for the voltage drop, thereby maintaining operation for a short period.
● Motor Overheat Protection
By using the optional input/output expansion card, analog input AI3 can accept input from a motor temperature sensor (PT100, PT1000). When the motor temperature exceeds the pre-warning value, the drive outputs a pulse signal to indicate overheating. When the motor temperature exceeds the overheat protection value, the drive provides a fault output for proper motor protection.
● Powerful Background Software
The background software enables the upload and download of inverter parameters and provides real-time oscilloscope functionality.
● Background Function Code Operation Interface

● Restore User Data
When parameter confusion occurs due to debugging or incorrect operation, you can choose to restore factory settings or recover previously saved user data to avoid parameter disorder.
● Fieldbus Support
Supports bus communication modes for easy connection to various peripheral devices.
Supports RS485, the company's proprietary fieldbus protocol.
● Open-Loop Vector Control for Synchronous Motors
The ZPS-7000 series enables encoderless synchronous motor control, making synchronous motor control more accessible.
● Independent Air Duct Design
Effectively enhances the protection level of the inverter, adapting to complex and harsh field environments, improving product reliability, and extending service life.
The independent air duct, combined with flange mounting, effectively solves heat dissipation issues inside the control cabinet, facilitating the cooling design of electrical cabinets for customers.
● Multiple Installation Modes
0.75~160kW: Wall-mounted, flange (through-wall) installation; 200~400kW: Floor-mounted installation
Note: The above power ranges are based on the G-type model.
● Easy Fan Replacement
The fan is easy to replace, simplifying maintenance and cleaning.
