Dedrive Pro 880

Developed by a crane manufacturer for crane manufacturers: with the implementation of the Demag CraneControl crane controller, the Dedrive Pro 880 offers pre-configured software solutions to minimize engineering tasks.

The Advantages at a Glance

Efficient Engineering

With crane control implemented, the Dedrive Pro 880 offers pre-configured software solutions to minimize engineering tasks.

• Precise control and monitoring with direct torque control (DTC)
• High performance in load handling through a sensorless anti-sway system
• Exact load handling through synchronized control of multiple hoists
• Torque distribution of mechanically coupled gearmotors
• Mechanical brake control with verification system
• Lower energy consumption through integrated efficiency calculator

High Security

A safe torque off STO (Safe Torque Off) is already integrated as standard. Other functions are supported by an optional security module (as of 01.2017):

• Safe Stop 1 (SS1)
• Safe Emergency Stop (SSE)
• Safe Brake Control (SBC)
• Safe Speed ‹‹Limiting (SLS)
• Safe maximum speed (SMS)

Easy Commissioning

• Drive Composer software tool for commissioning, configuration and monitoring
• Drive Composer Pro: Custom configuration window, control diagrams of system configuration and adjustment of security functions.

Comfortable handling

• Intuitive control panel for easy menu navigation and convenient parameterization and diagnostic function

Recoverable Configuration

• Logging of all software settings and parameters to a removable memory drive. This ensures rapid commissioning after replacing equipment.

Direct Sync

• Connection of several frequency converters for direct synchronized drive-drive communication (D2D) without additional hardware.

Open Communication

• Data exchange with numerous automation systems using a plug-in fieldbus adapter

Proactive Service

Extensive preventive maintenance service functions (permanent counter), for example:

• Crane service hours counter.
• Inverter service hour counter.
• Fan running time.
• Brake activations.
• Load spectrum of the hoist.
• Drive activations.

Maximum Transparency

• Remote diagnostic tool with integrated web server
• Recording and storage of process data and drive data.
• Process monitoring through integrated alarm and fault message functions.
