Features

Explosion protection

• ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length

Emergency Off

• The Emergency Off function prevents unexpected starting in compliance with EN 60204‑1, implemented according to EN 954‑1, Category 3, respectively SIL2 with Accessory kit S

Power unit

• 12- and 24-pulse input optional possible. For this reason gi line supply(basic fundamental) of 99.9 % is possible
• This corresponds to the EMC Directives (EN 61800‑3 environment 2) as a result of the line filter integrated as standard
• Low harmonics as a result of the integrated line reactor
• Long motor cable lengths possible inherent to the system
• 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
• 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 1000 m away in the main control room via RS485
• Extensive functions using the Windows-based PC operator control program

Communication

• Communication via 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 I

• Two closed-loop control types for induction motors:
  • Speed control
  • Torque control
• Full 4-quadrant operation with regenerative braking as standard

The following generally apply

• Automatic slip compensation
• Stall protection using current limiting control
• Flying restart circuit to connect to a rotating motor
