Installation & Operation Essentials

• Connect 3-phase AC or DC supply – check polarity for DC.
• Use external braking resistor with GTR7 for regenerative loads.
• Ensure 50mm clearance around heatsink for airflow.
• IP20 – mount in a clean, dry control cabinet.
• Parameterize via keypad or KEB software tool.

Delivery, Warranty & Support

• Pre-shipment: Full functional test and calibration.

5 Professional FAQs – Expert Selection Guide

• Q: What is the advantage of 8 kHz switching over standard 2 kHz?
  Lower motor noise, less harmonic distortion, and smoother torque at low speeds – but slightly higher drive losses.
• Q: Can I use this drive for both servo and induction motors?
  Yes, it supports both. Set motor type in parameter P2.1 – choose synchronous or asynchronous.
• Q: What is the short-time current limit used for?
  It provides extra torque for acceleration or load shocks. Max 75A for up to 60 seconds (dependent on thermal model).
• Q: Is the GTR7 braking transistor suitable for high-inertia loads?
  Yes, but you must add an external resistor. The GTR7 controls the chopper, not the dissipation.
• Q: How do I verify correct installation?
  Check DC bus voltage via monitor parameter d.15. Run motor without load first, then ramp up.
