2. Foreword
This workshop manual (WM) is a collection of
technical data and functional descriptions for
the standard vehicle.
It is intended as a guide which should be kept
at hand at all times, to help explain the
technical features of the vehicle and
consequently ensure that maintenance and
repair are carried out correctly.
The workshop manual is updated on a regular
basis with additional sheets.
Updating workshop manuals
Our range of equipment is subject to continuous
development and improvement. A consequence
of this is that components or assemblies are
sometimes replaced or their function changed.
In order to guarantee that the owner of a
workshop manual is always in possession of
up-to-date and relevant doumentation, the
manual must be updated using the method
described overleaf.

3. Updating workshop manuals
1. Replacing incorrect sheets
If a sheet contains an error, e.g. if adjustment
values have been altered, the sheet in
question must be replaced.
The new sheet can be identified by the
information at the left-hand side of the page
footer (1). The date of issue is updated here
in the Issue line (2). The date of issue of the
sheet which needs replacing is specified in
the Replaces issue line (3). The sheet no.
remains the same (4).
Every time a change is made, the cover
sheet is replaced. The date of first issue
and the date of the last update are shown in
field 9. This means that the workshp manual
edition is immediately obvious.
2. Inserting new sheets
If new, altered or additional components are
introduced to the series, it may be necessary
to insert one or more additional sheets.
An additional sheet can be identified by the
changes at the left and right of the page
footer (5 + 6).
At the left, in the Issue line, is the current
date of issue (7). At the right, the additional
sheet is marked with the sheet no. with a
consecutive index (8).
The list of contents for the assembly in
question must also be replaced.
We send new sheets, whether they are
replacement or additional sheets, and new
lists of contents, to all the vehicle owners we
know of by mail.

Drive motor
10/02
01
General
The drive motor is a 3-phase alternating current
motor (asynchronous motor with squirrel cage
rotor).
It is controlled by a converter which generates
sinusoidal 3-phase alternating voltage from the
battery voltage (please see "Converter, General").
The 3-phase stator rotary field generates voltage in
the squirrel cage rotor (1) by breaking magnetic
field lines (on the principle of voltage induction).
This induced voltage is short-circuited by the short-
circuit rings (2). The power generated in this way in
turn generates a rotor magnetic field. This rotor field
attempts to follow the stator rotary field, i.e. the
rotational speed of the stator field is higher than that
of the rotor field (asynchronous).This difference in
rotational speed is known as slippage.
This functional principle means that carbon brushes
are no longer needed in the motor, and
consequently that soiling in the inside of the motor
from carbon brush dust is no longer a problem.
In this way, by changing the rotational speed of the
stator field (frequency of the alternating voltage),
the speed can be changed, and by changing the
voltage the current can be changed indirectly, and
consequently the torque regulated (please see
"Converter, The principle of speed/torque
regulation").
The speed is detected by a speed sensor integrated
in the motor (sensor bearing (3)), which is
connected directly at the converter (please see
"Drive motor, Speed sensor").
Also integrated in the motor (in the stator coil (4)) is
a temprature sensor, which protects the motor from
overloading (please see "Drive motor, Temperature
monitoring"). This is also connected directly at the
converter.

Temperature monitoring
The motor temperature is sensed by a temperature
sensor integrated directly in the stator coil (1).
The temperature sensor works by the same
principle as a PTC resistor (increasing temperature
= increasing resistance value), however this special
version (silicon sensor) has an almost linear course
(see characteristic curve).
The temperature sensor is supplied by the conver-
ters (up to 04/2005) with a constant current I = 2.56
mA (cf. "Converters, terminals, control signals").
For converters from 05/2005, this current is appr.
1.6 mA.
In this way, the measured temperature is sent back
to the converter as a voltage value.
At 20°C, this represents a voltage of about 1.4V/
0,9V (145°C = 3.35V/2V, 150°C = 3.45V/2,15V).
The temperature measured in this way is sent to the
FPS via the CAN bus 2 (please see "CAN bus"). In
the event of excess temperature, the FPS then
issues an error code, which is sent via CAN bus 1
to the LAS module (entry in the error memory) and
to the display (to be displayed). The result is a
power reduction.
Error code (see "Error codes")
FE25: Temperature > 145°C, 50% power reduction
(for converters from 05/2005 Vred = 2.5 kph)
FE26: Temperature > 150°C, motor is switched off
FE27: Temperature sensor faulty or connector
pulled out (please see "Drive motor,
Connections");
The motor is switched off.
(for converters from 05/2005 Vred = 2.5 kph)

Temperature monitoring
Test
To test the sensor, connector X2 at the motor must
be disconnected. A resistance measurement must
then be carried out on the sensor side of the
connector between X2.1 and X2.3. Finally, the
temperature at the motor housing must be
measured. The measured values should
correspond with those shown in the table to the
right ± 20 .
Important note on measuring the insulation
resistance at the motor:
The temperature sensor must be short-circuited
without fail for insulation measurement,
otherwise the sensor will be damaged by the
high test voltage!

Speed sensor
The speed sensor is designed as a "sensor bearing"
(ball bearing with speed sensor) and is located inside
the motor, pressed onto the rotor shaft (1).
Structure
- Connecting lead (2)
- Outer sensor ring (3)
- Inner pulse ring (4)
- Deep-groove ball bearing (5)
It is connected directly to the converter, which supplies it
with 12V power and evaluates it (please see "Converter,
Connections, Control signals").
The two sensor signals (signal A and signal B) are also
sent to the FPS.
Remark: Monitoring of the speed sensor signal by the
FPS is only possible with the so-called "FPS
2".
On vehicles with "FPS 1", the speed sensor
is not connected to the FPS (please see
"FPS").
The converter needs the sensor information in order to
regulate the speed of the drive motor.
If no signals arrive at the converter, the motor is only
controlled by a minimum.
Remark: The converter (to 04/2005) itself does not
generate an error code if the sensor is faulty!
The converter from 05/2005 generate an er-
ror code (see "error code").
The FPS (from FPS 2) compares the speed sensor
information that it has recorded itself, with the
information it receives from the converter via the CAN
bus 2.
If there is a difference between these two speed values,
the FPS generates an error code "FE 28" (please see
"Error codes"). However, this does not have an effect on
the way the motor behaves.
As a result, the speed sensor fails to detect a pulled plug
(with the converters used up to 04/2005 no error code,
only minimal motor actuation). For converters from 05/
2005 onwards, a pulled plug causes the truck to come to
a standstill with the error code "FE 28"!
