It is a specialized inverter for cranes, which is part of Konecranes' Dyna Move Vector III drive system (a series with phased obsolescence and upgrade support). It is mainly used to match small and medium-sized industrial cranes, responsible for adjusting the motor speed during crane movement and lifting operations. It can also be upgraded and retrofitted through dedicated kits, and is compatible with the replacement and upgrading of old - generation crane travelling inverters, which is convenient for users to maintain and update equipment.

Power Supply Requirements: Referring to the general electrical parameters of the same series of D2S inverters, it is adapted to a three - phase AC power supply of 380 - 500VAC (with a tolerance of ±10%), and supports a frequency of 50/60Hz (with a tolerance of ±5%), which is in line with the universal industrial power supply standards and has strong adaptability to power grids.

Supporting Configuration: The inverter is equipped with a dedicated D2S display panel (part number 52314515) for real - time monitoring and parameter adjustment. It can also be configured with an I/O expansion board (NX OPTB 9) to meet the extended needs of signal input and output in complex operating environments.

Targeted Control Performance: It adopts vector control related technologies (matching the Dyna Move Vector III drive type). It can precisely regulate the motor speed during crane lifting and walking, reducing mechanical impact during start - up and braking, and protecting the crane structure and loaded goods.

Easy Retrofit & Maintenance: Konecranes provides special upgrade kits for the D2S series inverters. This model can be smoothly upgraded and replaced with corresponding kits when it needs to be updated. Meanwhile, the pre - designed installation structure makes the replacement process fast and convenient, minimizing the downtime of crane operations.

Safety Protection Design: It has strict safety specifications. For example, there are clear warning requirements in the operation manual: after turning off the power supply, it is necessary to wait 5 minutes before opening the cover after the display is off to avoid electric shock risks caused by residual high voltage. In addition, it can cooperate with the crane's electrical system to realize fault protection related to motor connection and power supply abnormalities.

It is highly compatible with Konecranes' own crane control systems. The D2S series, including this model, can share the same basic inverter design with some D2M series products, and can be flexibly matched according to the crane's motion mode and application scenarios. When purchasing and replacing, users only need to provide the original order number and electrical installation position to ensure the consistency with the original equipment.
