General; Applications; Technics Of The Kfm05A - gefran KFM05a Instruction Manual

1. General

The drive-system KFM05a includes frequency inverter and motor in one unit. In contrast to other
drive systems, where the frequency inverter is installed separate, the KFM05a integrates the
frequency inverter within the motor. In addition there is a sensor for rotor position. This combination
makes the KFM05a a positioning drive in the lower power range.

1.1 Applications

- Linear axis
- Angle positioning
- Handling machines
- Robotics
- Packaging machines
- Assembly lines
- Special-Purpose machines
- Conveyers
- Doors
- Knead machines, dough-working

1.2 Technics of the KFM05a

The 3-phase asynchronous motor, electronics and position sensor form one integrated unit.
Customer orientated control- and positioning possibilities are realized via several field bus
interfaces.
The internal position-encoder resolution is 2048 pulses / revolution.The "stiff characteristic" of the
position control depends on the parameter-setting and can be several pulses.
The program is stored in the FLASH-ROM, so standard software resp. customer specific software
can be loaded resp. changed in a simple way without handling the KFM05a, also by the customer
(it is possible to save the program), because a basic software (boot sector) remains in the
KFM05a.
The program-tool E@syDrive for KFM05a contains modules for parameter-configuration and
loading / saving, loading firmware and a software-oscillograph for motor optimizing and diagnosis.
An RS 232 interface for parameterizing and diagnosis is standard.
Different fieldbus connections are provided in option (CANopen is already available). This is
another component set, not an additional board. With this all functions can be controlled via
fieldbus.
For Hardware-control 5 digital control inputs, 3 digital control outputs (24 V via opto-coupler,
potential free) and 1 relay contact are available. Furthermore, 2 analog inputs are implemented. In
addition, operating and diagnostic states can be displayed via 6 LEDs. A safety relay can be
included as an option for the function "Safe Stop".
The KFM05a requires a single-phase, 230 VAC, 50 Hz power supply. The necessary filters
according to the EMC-guideline are standard equipment.
Optionally, a DC/DC-transformer with additional 24 V supply for fieldbus and electronics is
available. In this case, the internal auxiliary supply is not available.
Another option is the KFM05a with integrated holding brake or emergency stop brake (controlled
by 24 VDC or 230 VAC), the brake relay 30VDC/1A is already on the controller board.
The KFM05A can be delivered in different housings with different connection configurations.
