Functional Features:
- Advanced PROFIBUS and analog communication interfaces
- Expanded firmware capabilities for complex motion functions
- Up to 32 position recipes via I/O option card
- Internal blower cooling for power section thermal stability
- Bidirectional motor control for single- and multi-axis configurations
Structural Characteristics: Modular connectors (X1–X21) for control voltage, feedback, communication, and I/O. The drive includes firmware module slot, contact protection, and a dynamic brake (Zks) resistor of 6 Ω.
Application Scenarios: Packaging, printing, CNC machinery, material handling, and high-load continuous-motion environments.
Installation Requirements:
- Minimum top clearance: 150 mm; bottom clearance: 80 mm
- Maximum installation elevation: 1000 m
- Branch circuit protection: 20 A (040) / 70 A (100/200) fuse per UL
- Use 60/75 °C copper wire only, class 1 wire
- Required wire size per UL 508 A
Usage Notes:
- Firmware must be purchased separately and loaded during commissioning
- Default communication mode is SERCOS; analog mode requires “AN” option card in slot 1 and parameter changes (P-0-0011 set to “Analog”)
- Fault relay (X3.12–X3.14) should be wired into E-Stop loop for safety
- Ensure 24 V enable signal (X3.1) is held high to activate power stage
- Do not enter service area with pacemakers or metal implants
