General Safety Instructions | 2
ma_dr_g6-modbus-20332669_en 7
2 General Safety Instructions
The products are developed and built according to the state of the art and recog-
nized safety rules. Nevertheless, their use may create dangers to life and limb of
the user or third parties or damage to the machine and other material property.
The following safety instructions have been created by the manufacturer for the
area of electric drive technology. They can be supplemented by local, country- or
application-specific safety instructions. This list is not exhaustive. Non-observance
of the safety instructions by the customer, user or other third party leads to the loss
of all resulting claims against the manufacturer.
NOTICE Hazards and risks through ignorance!
a) Read the instructions for use.
b) Observe the safety and warning instructions.
c) Ask if something is unclear.
2.1 Installation
DANGER Electrical voltage at terminals and in the device!
Danger to life due to electric shock !
üFor any work on the device
a) Switch off the supply voltage.
b) Secure it against switching on.
c) Wait until all drives has been stopped in order that no regenerative energy can
be generated.
d) Await capacitor discharge time (min. 5 minutes). Measure DC voltage at the
terminals.
e) Never bridge upstream protective devices. Also not for test purposes.
NOTICE Use of unsuitable voltage sources!
Electric Shock!
a) Use for the connection only suitable voltage sources with safe isolation (SELV/
PELV) in accordance with VDE 0100 with nominal voltage of DC 24 V ±10 %.
b) Pay attention on a sufficient overvoltage category of the voltage supply.
c) With existing or newly wired circuits the person installing the units or machines
must ensure that the PELV requirements are met.
For a trouble-free and safe operation, please pay attention to the following instruc-
tions:
• The electrical installation shall be carried out in accordance with the relevant re-
quirements.
• Cable cross-sections and fuses must be dimensioned by the user according to
the specified minimum/maximum values for the application.
• For drive converters that are not isolated from the supply circuit (in accordance
with EN 61800-5-1) all control lines must be included in other protective meas-
ures (e.g. double insulation or shielded, earthed and insulated).
• When using components without isolated inputs/outputs, it is necessary that
equipotential bonding exists between the components to be connected (e.g. by
the equipotential line). Disregard can cause destruction of the components by
equalizing currents.

2 | General Safety Instructions KEB Automation KG
8 ma_dr_g6-modbus-20332669_en
2.2 Start-up and operation
The start-up (i.e. the starting of normal operation) is prohibited until the machinery
has been proved to conform to the provisions Directive 2006/42/EG and Directive
2014/30/EU; EN 60204-1 must be observed.
WARNING Wrong parameterization
Unintentional behaviour of the drive
üDuring initial start-up or replacement of the drive controller
a) Secure motors against automatic restart.
b) Check whether the appropriate parameter list for the application has been im-
ported.
WARNING Software protection functions as sole protection.
Protection function in case of software problems without function.
üSecuring a unit solely with software-supported functions is not sufficient.
a) Install external protective measures (e.g. limit switch) that are independent of
the drive controller.
2.3 Maintenance
DANGER Unauthorized exchange, repair and modifications
Unpredictable malfunctions
a) The function of the drive controller is dependent on its parameterization. Never
replace without knowledge of the application.
b) Modification or repair is permitted only by KEB Automation KG authorized per-
sonnel.
c) Only use original manufacturer parts.
d) Infringement will annul the liability for resulting consequences.

3 Product description
3.1 Functional description
This manual describes the software extension of the control board COMBIVERT G6 with
MODBUS.
It is based on the standard control board analog/digital. It is designed to be used on any
G6 with or without STO functions.
This manual describes the fieldbus parameter group and the behaviour of the MODBUS
driver.
All DIN666019II behaviours and services comply with the G6 standard analog/digital. For
more information, see the documentation on DIN66019II.
3.2 Validity
The described software is only valid for devices with material number in accordance with
the following key:
xxG6CDx-YSxx
The assignment of the firmware depends on the hardware of the power unit:

3.3 Hardware description
The D-Sub DE-9 socket (X4A) is intended for the connection to DIN66019II or MODBUS.
The socket supports the RS232 or alternatively the RS485 transmission standard. All
other connections correspond to the standard control board analog/digital.

4 | MODBUS functions KEB Automation KG
10 ma_dr_g6-modbus-20332669_en
4 MODBUS functions
4.1 Supported functions
The KEB G6 MODBUS interface supports the following functions defined in the Modbus
standard:
• 3: 'Reading Holding Registers'
• 4: 'Reading Input Registers' (for KEB, identical to function 3)
• 6: 'Preset Single Register'.
• 16: 'Preset Multiple Registers'.
These functions only support 16-bit access to parameters.
Therefore, two additional functions for accessing 32-bit parameters were created:
• 100: 'Read Registers 32':
Reading multiple 32 bit registers (indirect set addressing through Fr09)
• 101: 'Write Registers 32':
Writing multiple 32 bit registers (indirect set addressing through Fr09). For those func-
tion the datagram building is similar to 3 / 16 functions.
4.2 Parameter addressing
The addresses of the parameters (register) are divided into different groups. Each of
those groups has its own accessing method:
•0000(hex)…1FFF(hex):
This group is defined to access to mapping parameters. Parameters are set up to be
redirected to the mapping list.
•2000(hex)…5EFF(hex):
In this address area the parameters of the inverter control board are mapped by a fixed
algorithm. Please keep in mind that in this address area access is done with indirect
set addressing (with Fr09). This means when writing/reading one parameter in different
sets you have to set the set indicator (Fr09) previously before access.
•5F00(hex)…5FFF(hex):
This block consists of the operator parameters.
4.3 Watchdog function
The MODBUS driver supports fieldbus monitoring. With regard to the settings Pn05 and
Pn06, the watchdog is controlled via the MODBUS communication.
This function only starts after the first valid datagram exchange.
