Features
Explosion protection
- ATEX-certified for motors located in hazardous zones
- A main contactor is not required
Safe Torque Off
- The Safe Torque Off function prevents unexpected starting in compliance with EN 60204-1, implemented according to EN 954-1, Category 3
Power unit
- This corresponds to the EMC Directives (EN 61800-3 environment 2) as a result of the line filter integrated as standard
- Low harmonics fed back into the line supply as a result of the integrated line reactor
- Output filter to permit longer motor cables
- Insulation monitoring for IT line supplies for 500 / 690 V drive units as well as ground fault monitoring for TN and TT line supplies integrated in the 400 V drive units
- Wide supply voltage range
- Low motor noise and low drive inverter and motor losses as a result of the optimized pulse pattern
- Normal fuses can be used for protection (gL characteristic)
Control section
- High level of personnel and plant protection through protective separation between the analog and digital control peripheral and the power unit according to VDE 0106 / EN 50178
Operator control and setting
- Transparent operator control and setting using a menu-prompted 4-line plain text display with membrane keypad at the drive inverter – or up to 1,000 m away in the main control room via RS485
- Extensive functions using the Windows-based PC operator control program
Communication
- Communication via a conventional terminal strip with freely-programmable digital and analog inputs / outputs, with
- parameterizable limit value signals
- parameterizable timers
- parameterizable damping elements
- parameterizable drive inverter behavior when inputs / outputs respond
- Communication and parameterization via
- PC using IMS (Inverter Management Software) via RS232 / RS485
- external operator panel via RS485
- bus systems such as Profibus DP or Modbus RTU
Drive behavior for DYNAVERT T
- Synchronous and asynchronous motors can be controlled
- Two closed-loop control types for induction motors:
- field-oriented control for applications demanding a high dynamic performance
- space-vector control for standard applications (without feedback)
- Optimum braking without supplementary equipment using super-saturation control
The following generally apply:
- Automatic slip compensation
- Stall protection using current limiting control
- Flying restart circuit to connect to a rotating motor
- Automatic adaptation of the overload times
- Parameterizable DC braking for precise braking down to standstill
- Closed-loop torque control
