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 g1line 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
- - parameterizable limit value signals
- 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 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
