■ Overview
"Special technology" comprises rotary pulse encoders of 1LE1
motors (with the exception of 1LE1 with order code F90 – version
"Forced-air cooled motors without external fan and fan cover"
and 1PC1).
1LE1 motors with order codes F70 (mounting of separately
driven fan), F01 (mounting of holding brake (standard arrangement))
and F01 + F70 (mounting of brake and separately driven
fan) from the modular mounting concept can be combined with
rotary pulse encoders LL 861 900 220, HOG 9 DN 1024 I and
HOG 10 D 1024 l from the "Special technology" range.
The length of the motor increases by l when the rotary pulse encoder
is mounted. For an explanation of the additional dimensions
and weights, please refer to "Mounting technology",
"Dimensions and weights" from page 1/104.
The rotary pulse encoders of "Modular technology" and "Special
technology" are fitted as standard with a protective cover made
of non-corrosive sheet steel.
For mounting of rotary pulse encoders with order codes G11 and
G12 for frame sizes 71 to 315 and with order codes G04, G05,
and G06 up to frame size 160, a protective cover (order code
G43) is supplied as standard.
LL 861 900 220 rotary pulse encoder
Introduction
Mounting technology
Special technology
For frame size 180 and above, a protective cover is not supplied
as standard when rotary pulse encoders are mounted for order
codes G04, G05, G06, G07 and G08.
For mounting of rotary pulse encoders with order codes G11,
G12 + F70 (mounting of separately driven fan): The cable end is
connected to a connector that is located outside the fan cover.
The fan cover does not have to be removed to connect the rotary
pulse encoder. The rotary pulse encoder can be connected to
the main terminal box or an auxiliary terminal box where necessary.
For mounting of rotary pulse encoders with order codes G04,
G05, G06 + F70 (mounting of separately driven fan):
• Up to frame size 200, the fan cover has to be removed to connect
the rotary pulse encoder. The rotary pulse encoder can
also be connected to the main terminal box or an auxiliary terminal
box where necessary.
• As of frame size 225, the fan cover does not have to be removed
to connect the rotary pulse encoder. The rotary pulse
encoder can be connected to the main terminal box and can
be connected to the auxiliary terminal box where necessary.

With its rugged construction, this rotary pulse encoder is also
suitable for difficult operating environments. It is resistant to
shock and vibration and has insulated bearings.
The LL 861 900 220 rotary pulse encoder can be supplied already
mounted.
Order code G04
The LL 861 900 220 rotary pulse encoder can be retrofitted. The
motor must be prepared for this. When the motor is ordered, the
option "Prepared for mountings, center hole only", order code
G40, or the option "Prepared for mountings with shaft D16", order
code G42, must be specified (see "Mechanical version and degrees
of protection" on page 1/76). The rotary pulse encoder is
not part of the scope of supply in this case.
The version of the rotary pulse encoder with a diagnostics system
(ADS) can be supplied by Leine and Linde.
