1.1 Introduction
1.1.1 Rexroth IndraDrive Mi
Rexroth IndraDrive Mi is an innovative system solution within the Rexroth In‐
draDrive platform, consisting of synchronous servo motors (on the basis of
Rexroth IndraDyn S) with integrated inverters and control sections.
1.1.2 Features
Fig.1-1: Rexroth IndraDrive Mi – Features
Project Planning Manual |Rexroth IndraDrive Mi Electric Drives
and Controls
|Bosch Rexroth AG 1/152
System Presentation

In the following points, the system solution Rexroth IndraDrive Mi differs from
a standard solution with Rexroth IndraDrive and Rexroth IndraDyn:
● Limited performance levels and exclusively available on the basis of
Rexroth IndraDyn S, i.e. no linear and kit motors
● SERCOS interface as master communication
1.2 Drive System Rexroth IndraDrive Mi
1.2.1 Components
General Information
The drive system Rexroth IndraDrive Mi consists of the following components:
1 Distributed servo drive KSM ; 1a: basic motor ; 1b: electronic system of
drive (power section and control section)
2 Terminal connector RHS (to close the SERCOS ring)
3 Hybrid cable RKH (for power and communication)
4 Electronic control system KCU (power supply and signal conversion)
Fig.1-2: Components
The distributed servo drive KSM consists of 2 parts:
● Servo motor (on the basis of Rexroth IndraDyn S)
● Electronic system of drive, consisting of control section and power section
The hybrid cable RKH replaces the following individual cables:
● Motor power cable
● Encoder cable
● Control voltage and signal exchange cable
● SERCOS cable
The hybrid cable is supplied in ready-made form with connectors.

1.2.2 System Structure
The supply unit which is used significantly defines the system structure.
Possible supply units:
● Rexroth IndraDrive supply unit HMV01.1E/R or HMV02.1R
●Rexroth IndraDrive converter HCS02.1 or HCS03.1 (makes sense if an‐
other axis is required)

1.2.3 Overview of Functions
Firmware Functions (Functional Packages)
For the available firmware functions, see chapter "Functional Pack‐
ages" of the Functional Description for firmware MPB04VRS or
higher.
Hardware-related functional restrictions as compared to drive controllers with
CSB and CSH control sections:
●No safety technology
● No analog inputs or outputs
● No digital and analog I/O extensions
1.3 Type Code
1.3.1 Introduction
The type code is the basis of each purchase order of a Rexroth product.
It unequivocally describes all variants which can be supplied.
● Distributed servo drive KSM
● Electronic control system KCU
● Firmware ≥ MPB04-V20
For product selection and purchase order, take the following aspects into ac‐
count:
● Observe detailed information and instructions in the chapters "Technical
Data of the Components" and "Notes on Project Planning"
● Before placing a purchase order, have our sales representative check
whether individual options are available
The following figure illustrates the basic structure of the type code.
Our sales representative will help you with the current status of
available versions.

|Bosch Rexroth AG 9/152
System Presentation

Explanation of the Type Code
The type code has the following basic structure:
●Product
KSM Designation of the line
●Size
The size defines important mechanical dimensions. In addition, the rotor inertia
is distinguished in column 11.
Abbrev. column <12> : 1 Rotor inertia reduced
6 Rotor inertia normal
●Length
Within one line, increasing length is graded by code letters in alphabetic order.
●Winding
The two-digit sequence of numerals, multiplied by 100, makes the rated speed
applying to the corresponding winding variant.
●Cooling mode
N: Natural convection
●Motor encoder
Rexroth IndraDrive Mi motors have been equipped with an integrated encoder
system. To control the motor speed or position the motor, the drive controller
needs the current motor position.
Option Encoder type
S1 Optical encoder single-turn, position detection absolute over 1 motor rev‐
olution with a resolution of 128 x 213 pieces of information per revolution
M1 Optical encoder multi-turn, position detection absolute over 4096 motor
revolutions with a resolution of 128 x 213 pieces of information per revolution
Fig.1-8: Motor encoder
●Connection system
Connection for hybrid cable RKH
●Shaft
To connect the machine elements to be driven to the motor shafts, there are
the following options.
Option Design Detail
GPlain shaft With centering hole on the end face with
thread "DS" according to DIN 332, part 2,
edition 05.83
PShaft with keyway 1)
1) Keyway according to DIN 6885, sheet 1, edition 08.68 (for details see dimensional
drawing!)
Fig.1-9: KSM output shafts
Distributed servo drives KSM are balanced with the complete key.
The corresponding key is not part of the scope of supply.
