AKT2G-AC-FAN-001

Fan cartridge for EtherCATClosed Ethernet ofr Control Automation Technology. EtherCAT® is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT is to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. and Bus Terminals

The AKT2G-AC-FAN-001 fan cartridge is used for forced ventilation within the terminal housing and ensures better heat dissipation from the housing.

  • It extends the thermal operating range of EtherCAT Terminals (AKT2G-xxx) and K-Bus Terminals (AKT-xxx) and offers a wide range of new application options.
  • The cartridge is installed on the underside of the terminal segment and covers a width of four standard terminals (4 x 12mm).
  • It consists of the fan, an installation plate, a terminal strip (24VDC, 0VDC, diag, mode) and a bracket for fixation on different terminal housings.

Mounting and Demounting

The AKT2G-AC-FAN-001 fan cartridge is snapped onto a 48-mm wide terminal group of Kollmorgen standard or high density (HD) terminals using the "8-channel/16-channel fan cartridge holder" supplied as an accessory.

Fan cartridge holder, 16-channel

The width of the individual terminals may be 12mm (single width) or 24mm (double width) or a combination of both.

The mounting of the AKT2G-AC-FAN-001 is described below by way of an example.

Mounting


  • Risk of injury through electric shock and damage to the device!

    Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals.

  1. Assemble the terminals to be ventilated into a group with a width of 48mm and snap the holder on the left in the lower ventilation cut-outs of the first terminal to be ventilated, as shown in Figure 8-20: "Engaging the holder for the fan cartridge".

    Figure 8-20: Engaging the holder for the fan cartridge

    The holder is correctly engaged when a clear click sound is heard.

  2. Push the fan cartridge onto the holder as shown in figure Attaching the fan cartridge. The holding tab and the recess (see figure Push fan cartridge with recess over holding tab) on the fan cartridge fit each other and close flush in a downward directionClosed The orientation components of a vector in space..

  3. Make sure that the latchingClosed The control word is used to activate the drive's latch status machine. The latch control word is processed independently of the EtherCAT® bus cycle. The status word is used to return the drive's latch status. tab is pushed into the groove until a click noise is heard as in "AKT2G-AC-FAN-001". The fan cartridge is now correctly attached.

Removal

  1. To dismantle, pull the fan cartridge off the terminal group in the direction of the arrow (see the following figure).

    Figure 8-22: Pull the fan cartridge off towards the front

  2. To detach the holder from the terminal, place a screwdriver between the terminal and holder (see the following figure) and carefully lever until the holder releases.

  • Clearance of the fan cartridge module

    When installing terminals with mounted fan cartridge module ensure that an adequate spacing (> 35 mm) is maintained between other components above and below the terminals (incl. fan cartridge) in order to guarantee a flawless operation of the fan cartridge and adequate ventilation of the terminals.

Basic Function Principles and Commissioning

Area of application

The AKT2G-AC-FAN-001 fan cartridge is delivered ready to operate. No adjustments need to be made to the device.

A typical application of the fan module is extension of the performance range of the terminals through forced cooling. This enablesClosed Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive. the AKT2G-SM-L15-000 EtherCAT servo terminal to operate with higher output current so that the performance is on a par with the AKT2G-SM-L50-000 with the benefit of a 50% smaller footprint.

A further application is extension of the operating temperature range of the terminals. Depending on the technical specification, the fan module enables the terminals to operate at temperatures of up to 70 °C. The exact terminal-specific information for this application can be found in the documentation for the respective terminals.
