General Safety notes
Read and observe this technical description before commencing assembly and commissioning
work.
General
Depending on their type of protection power drive-converters can have live, bare, possibly moving
or rotating parts and a hot surface during operation.
There is a risk of death, serious injury or material damage if the required cover is removed
inadmissibly, if the equipment is not used for its intended purpose or if the equipment is installed or
operated incorrectly.
All installation, maintenance and repair work must only carried out by qualified specialist personnel
(observe IEC 60364 resp. CENELEC HD 384 or DIN VDE 0100 and IEC 60664 or DIN VDE 0110

General Safety notes
Electrical Connection
When working on a live drive-converter observe the valid national accident prevention regulations
(e.g. BGV A2).
Electrical installation is to be made according to the relevant regulations (e.g. line cross sections,
fuses, PE-connection). Additional notes are in this technical description.
Compliance with the limit values demanded by the EMC legislation is up to of the manufacturer of
the system or machine. Additional information about shielding, grounding, configuration of filters
and cables is also provided in this technical description.
Operation
Systems or machines with built-in power drive-converters need if necessary additional monitoring
and protective devices in accordance with the valid safety regulations, e.g. law of technical
material, accident prevention regulations etc. Alteration of the drive-converters via user software is
allowed. This technical description is to be considered.
Do not touch live parts of the drive-converter immediately after disconnecting from the mains owing
to charged capacitors. Remove the main unit cover only after disconnecting the drive-converter
from the mains and a waiting period of at least 5 minutes (discharging period of the capacitors). In
the event of malfunctions, the discharging period of 5 minutes may be exceeded substantially.
In addition observe the instruction plates on the drive-converter. During operation hold close all
coverings and doors.
Among other things, guarantee presupposes the considering of this technical description.
Maintenance
Observe the documentation of SIEI-AREG especially concerning maintenance. Further information
is in this technical description.

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.

2.7 Mounting Hints
There must be a minimum distance to neighboring units, motors, walls, etc. to ensure a sufficient
cooling of the KFM05a.

2.8 Options
2.8.1 Option Brake
The KFM05A has a positioning-function and therefore in some applications it needs a brake in
case of power failure to hold the position and prevent uncontrolled movements.
Holding brake (24 V or 230 V)
This brake holds the KFM05a in standstill position until a positioning operation is again possible. A
braking out of the motion is not recommended, because this, depending on the rotating mass,
would lead to higher wear and shorter life.
Emergency-stop brake (230 V)
This brake stops the KFM05A and the rotating mass out of the motion to standstill. This type of
brake is designed for higher load and is used for fast braking in handling-systems.
The KFM05a doesn’t need an additional relay board for the brake, because the relay is already
built in the KFM05a with brake. This relay switches safely the brake-power of the 24V brake. The
power 24V/0,5A must be provided by an external supply. The 24V-brake is directly connected to
the board; the 24V-supply is connected via X7:1 and X7:2.
There is also the possibility to directly connect the 230V-brake with the grid from within the
KFM05a. In this case, the brake is active whenever there is a power failure.
In addition, all brake variants can also be switched on and off externally, the brakes are connected
on a terminal block.
A KFM05a with brake always has a longer housing; therefore it is not possible to install a
brake additionally.
2.8.2 Option Safety relay
As an option, a safety relay can be installed at the factory. This is necessary if the KFM05a should
be used in applications in which security features are required. The safety relay can be activated
with the enable input X7:7 and then turns on the IGBT output. The normally open contact is
connected to the terminal X6:27 and X6:28 (30Vdc, 1A) which is connected to the other contacts.
