Oiltech Controls’s Insight – Why This KEB F5 Stands Out

• Wide input range (305-528V) handles unstable grids.
• Integrated braking transistor reduces external component cost.
• 599 Hz output enables high-speed spindle or servo applications.
• Compact IP20 housing fits standard cabinets.
• Proven reliability in hoisting, conveying, and pump control.

Suitable Equipment & Applications

• AC/DC motors up to 22 kW (30 HP)
• Conveyor systems, elevators, cranes
• Pumps, fans, compressors
• Machine tools and extruders
• Retrofit for older KEB or third-party drives

Installation & Operation Facts

• 3-phase AC/DC input – check polarity for DC.
• Use braking resistor with GTR7 for regenerative energy.
• Ensure sufficient clearance for air cooling.
• IP20 – install in a dry, dust-protected enclosure.
• Set parameters via keypad or software.

Delivery, Warranty & Support

• Shipping: 24-28 hours dispatch via FedEx, UPS, or DHL.
• Warranty: 12-month comprehensive coverage.
• Pre-shipment: Full functional test and parameter verification.

5 Professional FAQs – Expert Selection Guide

• Q: Can I use this drive with a single-phase input?
  No, it requires 3-phase AC or DC input. Use a phase converter if only single-phase is available.
• Q: What is the benefit of the built-in GTR7 braking transistor?
  It allows dynamic braking without an external chopper. Saves panel space and cost for high-inertia loads.
• Q: How do I set the switching frequency?
  Default is 2 kHz. You can adjust via parameter group P5. Higher frequencies reduce motor noise but may increase drive losses.
• Q: Is this drive suitable for 50 Hz and 60 Hz motors?
  Yes, it supports both. Set the motor rated frequency in parameter P2.2 accordingly.
• Q: What maintenance is recommended?
  Clean heatsink every 6 months in dusty environments. Check DC bus voltage via monitoring parameters.
