  • Page 15: Introduction

    This programming guide can be used for all FC 202 drives. The software version number can be read from parameter 15-43 Software Version. Type Approvals and Certifications The following table shows examples of possible type approvals and certifications for Danfoss drives.   NOTICE Drives of enclosure size T7 (525–690 V) are not UL listed.
  • Page 16 Programming Guide | VLT® Aqua Drive FC 202 Introduction For more information on UL 508C thermal memory retention requirements, refer to the section Motor Thermal Protection in the product- specific design guide. For more information on compliance with the European Agreement concerning International Carriage of Dangerous Goods by Inland Waterways (AND), refer to the section AND-compliant Installation in the product-specific design guide.

  • Page 17: Safety

    Programming Guide | VLT® Aqua Drive FC 202 Safety Safety Safety Symbols The following symbols are used in Danfoss documentation.   DANGER Indicates a hazardous situation which, if not avoided, will result in death or serious injury.   WARNING Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
  • Page 18 Programming Guide | VLT® Aqua Drive FC 202 Safety   WARNING UNINTENDED START When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage.

  • Page 19: Protection Mode

    Programming Guide | VLT® Aqua Drive FC 202 Safety Protection Mode Once a hardware limit on motor current or DC-link voltage is exceeded, the drive enters protection mode. Protection mode means a change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues for 10 s after the last fault and increases the reliability and robustness of the drive while re-establishing full control of the motor.
