Professional FAQ

• Q: What is the maximum output frequency for this drive?
  A: 599 Hz. However, for standard 4-pole motors, we recommend staying below 120 Hz to avoid mechanical stress. We have seen successful runs at 300 Hz with special motors.
• Q: Can I use this inverter with a DC bus supply?
  A: Yes, it is rated for AC/DC input. The DC link voltage should be within 430–750 V DC. This flexibility helps in shared DC bus systems.
• Q: What encoder types are compatible?
  A: TTL incremental encoders with 5 V or 24 V supply. We recommend using shielded twisted-pair cables for the encoder feedback to prevent noise.
• Q: How do I select the braking resistor?
  A: The built-in GTR7 brake transistor supports external resistors. Choose a resistor with at least 50 Ω and power rating matching your duty cycle. We often supply 100 Ω / 400 W for general use.
• Q: Is this unit suitable for hoisting applications?
  A: Yes, with proper braking resistor and encoder feedback. Ensure you enable the “hoist” parameter group for torque control during lift and lowering.
