Foreword

This Technical Manual has been written for all machine tool manufacturers. It
contains all of the information necessary for the mounting and electrical
installation of HEIDENHAIN inverter systems and HEIDENHAIN motors.
With each update, you will receive a set of supplementary pages free-of­charge. Always sort these pages into your Technical Manual immediately. In
this way, your manual will always be up-to-date.
You can use extracts from this manual to supplement your machine
documentation. If you increase the size of the manual format (17 cm x 24 cm)
by the factor 1.225, you will have DIN A4 format.
No documentation can be perfect. To stay up to date, documentation must
change constantly. It also thrives on your comments and suggestions for
improvement. Please help us by sending us your ideas.

2.3.2 UE 2xx compact inverter

With UE 2xx compact inverters,
the power electronics for all of
the axes and the spindle, as well
as the power supply for the
control are all contained in a
single unit.
The PWM signals are
transferred via internal 20-pin
ribbon cables.
If you are using a LE 426 M, you
will require in addition the
UV 102 power supply unit.

2.3.3 UE 2xxB and UR 2xx Compact Inverters

With UE 2xxB and UR 2xx
compact inverters, the power
electronics for all of the axes
and the spindle, as well as the

2.3.4 UV 102 power supply unit

The UV 102 power supply unit is necessary if you are
using a UE 2xx (not UE 2xxB) compact inverter with an
LE 426 M. It supplies the power to the LE 426 M and
leads the external PWM connections of the logic unit to
the UE 2xx compact inverter.

responsible for the power supply. It is available as an accessory with the
compact inverter (length 300 mm, Id. Nr. 325 816-01).

The 20-line ribbon cable connects the PWM outputs of the control with the
PWM connections on the compact inverter. One 20-line ribbon cable is
required for each axis/spindle. The 20-line ribbon cables for the connections on
the compact inverter are supplied as accessories with the UE 2xxB (length
200 mm, Id. Nr. 250 479-08; length 400 mm, Id. Nr. 250 479-10). If you are
using an additional UM 111 power module, you will need an additional 20-line
ribbon cable:

n UM 1xx power modules, depending on version
n PW 210 (or PW 110(B), PW 120) braking resistor

n KDR 120, KDR 140 or KDR 150 commutating reactor
n Line filters
n If required, UP 110 braking resistor module

2.4.2 UV 1x0 power supply unit

The UV 1x0 power supply units supply the
dc-link voltage as well as the power for the
electronics of the control and power
modules.
During braking, the motors feed energy into
the dc-link. This energy is converted into
heat by the UV 130 through the PW 210 or
PW 1x0(B) braking resistor, or returned to
the power line through the UV 120 or
UV 140.
The UV 120 and UV 140 can be driven only
with commutating reactor and line filter.

2.4.4 Current Consumption of the Entire Inverter System

The current consumption by the power modules from the 15-V and 24-V
supply unit strongly depends on their performance. If several high­performance power modules are used, the maximum permissible current for
the supply unit can be exceeded. Therefore the current consumption must be
controlled separately for the 15-V and 24-V supply units, especially when the
UV 150 is used with a UM 115. The intrinsic needs of the supply unit must also
be taken into account. The current consumption of the individual components
is listed in the specifications table.

The following limit values apply:

n 15-V supply unit: Max. 1.5 A
n 24-V supply unit: Max. 2.0 A

If the total current consumption exceeds one limit value, please contact
HEIDENHAIN.

Example:

Device 15 V power supply 24 V power supply

UV 140 0.38 A 0.31 A
UM 114 0.25 A 0.42 A
