ET 200pro FC

Operating Instructions, 11/2007, A5E01100763B AA

3.1.3 MMC interface (Micro Memory Card)

Description

The MMC interface can be used to back up frequency converter parameters on an external

MMC and, if required, download them back onto the frequency converter.

Possible fields of application for the MMC

The MMC can be used as a parameter memory:

● Uploading a parameter set onto an MMC

● Transferring parameters from an MMC when exchanging the frequency converter

● Automatic download of a parameter set from an MMC.

Note

Several parameter sets can be stored on an MMC. The file name clone00.bin is used in

the default setting. Other names can be set via P0804 (e.g., clone00.bin to clone99.bin).

Inserting the MMC

Precondition: The frequency converter must be disassembled.

The label must be facing down when the chamfered edge of the

MMC is pointing left.

The MMC must be pushed into the MMC slot as far as it will go;

it can only then be removed by pressing the eject button.

3.2 PTC/KTY84 interface

The PTC/KTY84 interface can be used as an option.

Description

The connection for a PTC/KTY84 sensor to the motor temperature monitor is integrated in

the motor connector.

WARNING

The motor temperature monitor is assigned to the line supply potential, dangerous touch

voltages are thus possible.

The frequency converter must be switched off-circuit before the motor temperature sensor

can be connected.
