LOHER DYNAVERT T PWM Inverters
LOHER DYNAVERT T PWM Inverters
General description
LOHER DYNAVERT T can be flexibly integrated into any automation concept – whether using conventional control technology or bus systems.
LOHER DYNAVERT T can be connected to any of the normally encountered line supply voltages – and can feed both synchronous and asynchronous motors. All of the drive requirements are taken into consideration from the word go – from the coupling, through the motor, cables, drive inverter, line supply situation and connection to the supervisory control system.
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 Windowsbased 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 LOHER 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
