Expert Review

“This drive is powerful yet easy to set up. The 29 terminals give great flexibility. I like the 8 parameter sets – perfect for multi-motor lines.” – Senior Drive Engineer, Powergear X

Manager’s Insight

“A reliable workhorse for 1.5kW motors. The PID and energy saving cut running costs. Simple to install and maintain.” – Product Line Manager, KEB

Application Scenarios

• Conveyor belts in packaging lines.
• Fan and pump speed control.
• Mixers and extruders in plastic plants.
• Machine tools and spindle drives.
• HVAC systems with VFD control.

Comparison with Similar Models

• 09F5A1D-2A0A – 2.2 kVA / 1.1 kW (lower power).
• 09F5A1D-4A0A – 4.0 kVA / 2.2 kW (higher current).
• 09F5A1D-3B0A – same power but with fieldbus.
• 09F5A1D-3A0B – with brake resistor included.

Frequently Asked Questions (FAQ)

• Can I run a 1.1 kW motor with this VFD?
  Yes, but set motor parameters correctly.
• What is the max cable length from VFD to motor?
  50 meters with shielded cable (unshielded: 25 m).
• Does it support Modbus or Profibus?
  Not built-in – use optional fieldbus module.
• Can I use it for single-phase input?
  No, it needs 3-phase 305–528 V AC.
• How to reset after overcurrent trip?
  Press STOP/RESET key or cycle power.

Experience-Based Tips

• Use external brake resistor for high-inertia loads.
• Set switching freq to 8 kHz for most motors (quieter at 16 kHz but may derate).
• Always connect shield of control cables at one end only.
• Save parameter set before changing – easy restore.

Selection Guide

• Step 1: Check motor power (≤1.5 kW for this model).
• Step 2: Verify supply voltage (305–528 V AC, 3-phase).
• Step 3: Decide if you need fieldbus – choose optional module.
• Step 4: For quick stop, order brake resistor separately.
• Step 5: For higher power, see 09F5A1D-4A0A.
