Functional Features:
-
Modular design with 4 plug-in expansion slots supporting EtherCAT/POWERLINK and various encoder interfaces (EnDat 2.2, Hiperface, Resolver).
-
Integrated C3-class line filter, brake resistor, and electronic safety restart interlock (PLd compliant).
-
All connections use plug-in connectors for easy wiring.
Application Scenarios: CNC machining centers, lathes, milling machines, grinding machines, robot joint drives, high-speed packaging and printing lines, injection molding machines, extruders, and textile machinery.
Working Principle: The drive converts the three-phase AC mains into a regulated DC bus via a rectifier, then uses IGBTs with selectable PWM switching frequencies to synthesize a variable-frequency, variable-voltage three-phase output. A vector control algorithm regulates the current to precisely control the connected servo motor’s torque, speed and position.
Installation Requirements:
-
Mount vertically in a control cabinet with adequate ventilation; allow clearance for heat dissipation.
-
Connect the three-phase AC input, 24 VDC control supply, and motor output via the specified plug-in connectors.
-
Insert optional communication/encoder modules into the 4 expansion slots as needed.
-
Ensure proper grounding and PE connection.
Usage Precautions:
-
Observe the derating curves: continuous current decreases with rising ambient temperature and altitude above 500 m.
-
Do not exceed the maximum motor cable length (25 m at 20 kHz switching frequency).
-
The integrated brake resistor can reach high temperatures during operation—ensure adequate spacing from other components.
-
The electronic safety restart interlock must be properly wired to prevent unintended startup.
