Oiltech Controls Insight

This Combivert F5 is a robust drive for heavy-duty motor control. Its wide input range (305-528V) handles unstable grids. The 599Hz output frequency suits high-speed spindles. The GTR7 brake transistor enables quick deceleration without external braking units. We recommend this for retrofitting older drives in hoisting or conveying lines. The 8 digital inputs provide flexibility for complex automation.

Frequently Asked Questions

• Q: Can this drive run on 230V single-phase input?
  A: No. The 19F5A1H-350F requires 305-528V AC 3-phase. Use a step-up transformer or phase converter if only 230V is available.
• Q: What is the maximum motor cable length?
  A: Keep motor cable under 50m for unshielded, or 100m with shielded cable to avoid reflected wave issues.
• Q: How do I connect a braking resistor?
  A: Connect the resistor to terminals B+ and B- (GTR7 brake transistor). Set the braking threshold parameter accordingly.
• Q: The drive trips on overcurrent. What should I check?
  A: First check motor insulation and cable short circuits. Then verify acceleration time and load inertia. Reduce torque boost if enabled.
• Q: Can I parallel this drive with others for larger loads?
  A: No. This model is not designed for parallel operation. Choose a higher-rated single drive for larger motors.

Selection Guide

• Choose 19F5A1H-350F for 30kW/60A applications with brake transistor.
• Select 19F5A1H-500F for higher current (80A) or 45kW motors.
• Use external braking resistors for high-inertia loads (hoisting, centrifuge).
• For IP54 protection, mount the drive in a separate enclosure with cooling.
• Configure digital inputs per your PLC outputs (PNP or NPN) via parameter selection.
