WARNING
Contact with live parts of electrical domestic installation can cause death due to electric shock.
Only connect the device and switch on the power supply if you are qualified to do so. Be sure to
comply with VDE guidelines and local wiring regulations.
!
NOTICE
Switching on the power supply of unparameterized products can lead to unforeseen consequences
such as malfunctions or material damage.
Switch on the power only after the device has been configured by the commissioning technician.
!
NOTICE
Position the SBM51/06 such that it is connected between two Danfoss frequency inverters on the bus
(internal nodes in the network). Terminate the Danfoss bus using an internal DIP switch in the first
and last frequency inverter. This means you are able to achieve the best immunity to disturbance for
the bus system.
During commissioning, ensure that the Danfoss bus system is connected correctly. The Danfoss bus
must not be connected the wrong way round.
If it is not possible to position the SBM51/06 between two frequency inverters (external nodes in the
network), terminate the bus using an 180 Ohm terminating resistor between the terminals P and N.
Activate the terminating resistor of the FI at the other end of the line.
The shield is positioned on the spring-type terminal (or clamp for older VLT models) on one side of
the FI only. The COM terminal on the SBM51/06 is not used and is only used in environments with
severe interference. Clarify connection with Danfoss Support.

NOTE
The bus-systems switch cabinet bus (DDC3000) and CAN bus (DDC4000) are identical. Hence, all
technical information relating to the switch cabinet bus also apply to the CAN bus.
Switch cabinet bus
When connecting the switch cabinet bus, use a cable of at least type JY(St)Y 2x2x0.8 Lg: two x two
leads stranded into a pair, plastic insulation and an electrostatic shield with a lead diameter of at least
0.8 mm. Use a stranded pair of leads for the data lines (+ and -) and another free lead for the ground
(0).
At the end of the switch cabinet bus (furthest point from the controller), install a terminating resistor
of about 180 ohms between the two data lines (+ and -). The terminating resistor is included with the
controller.
The maximum cable length for the switch cabinet bus is 200 m.
NOTE
For a connection to a DDC4000, the data rate of the CAN bus used must be 40 kBd. Use the

every Danfoss frequency inverter:
■the menus /01 and /02 for the frequency inverter with address 1
■the menus /03 and /04 for the frequency inverter with address 2, etc.
When using a DDC3000, the basic program of the SBM51/06 is expanded with additional DDC
software menus M090 according to the number of frequency inverters to be added. When using a
DDC4000, all 32 menus are automatically created.
Software Menu M090 and CD_SB51: Resync/Diag /31 Menu
The Resync/Diag menu is activated with parameter 2216. The SBM51/06 recognizes the menu used
by the DDC based on the menu number of parameter 2216.
The module manages the parameters as standard analog actual values in software menu /31 and
sends this as Q analog actual value 1 - Q analog actual value 8 to the automation station.
NOTE
The Resync/Diag menu is not explicitly registered with the automation station by the SBM51/06.
Parameter 2209 “External System OK”
Only applies for DDC3000.
Parameter 2251 “Analog Actual Value 4” and 2215 "Analog Actual Value 5"

SBM51/06Product Description
During operation:
■If an external selection is configured as a parameter set in the FI and parameter 2240/02 is “0”, is
larger than “4”, or becomes invalid, parameter 2211/02 then stays at the last valid value.
■If an external selection is configured as a parameter set in the FI and the parameter 2240/02 has
the values “1” - “2”, the SBM sets the selected parameter set and sends the setpoints.
NOTE
The SBM51/06 can switch to four parameter sets. Only the first two parameter sets can be parame-
terized in the SBM51/06. The settings are active in the FI for parameter sets 3 and 4.
Parameters 2215, 2251 and 2252
The parameters 2251, 2215 and 2252 have special functions which you enable in menu 32:
■Parameter 2251 - Parameterization communication error, setpoints
■Parameter 2215 - Communication error, actual values
■Parameter 2252 - Communication error, relay control
Software Menu M090 and CD_SB51 Menu 32
In software menu “Menu 32” (Address = 32), it is possible to set special parameters, e.g. maximum
number of FIs on the bus and the display of error values.
Parameter 2210 “Analog Actual Value 1”
Number of FIs found on the bus
Parameter 2240 “Q Analog Setpoint 1”
Selection of the maximum number of FIs that can be operated on the bus
Specifying a smaller number of FIs (e.g. three) reduces the cycle time, as only FIs with addresses 1,
2 and 3 are known on the bus. FIs with higher addresses are not taken into account and their param-
eters are not updated.
Parameter 2241 “Q Analog Setpoint 2”
Only applies for DDC3000:
■“0” →The existing parameters will be deleted.
■“1” →Following an interruption in bus communication, the frequency inverters will be configured
with retained parameters when registering again (parameter setpoint min/ max 1/2, current
setpoint, enable, freewheel stop, malfunction acknowledgment).
Parameter 2242 “Q Analog Setpoint 3”
The internal error counter display in the second FI menu
■“0” →Display inactive
■“1” →Display active
The counters are deleted when the SBM51/06 is restarted.

Function description
Function of the Analog Setpoint and Parameter Set Switching
The central unit specifies a frequency setpoint for each frequency inverter via the parameter 2240 “Q
analog setpoint 1” of the first respective menu, SBM51 gateway.
Using the following parameters of the first respective menus M090 and CD_SB51, you can scale the
specified parameters for the first parameter set of the frequency inverter:
■2241 “Q analog setpoint 2” for the minimum frequency setpoint (parameter 204)
■2242 “Q analog setpoint 3” for the maximum frequency setpoint (parameter 205)
You can specify the scaling for the second parameter set of the frequency inverter using the same
parameters of the second respective menu, SBM51 gateway.
If no parameters are set, the local frequency inverter settings apply.
Entering negative frequency setpoint values leads to incorrect setpoint calculation.
!
NOTICE
The values of parameters 2241 “Q analog setpoint 2” and 2242 “Q analog setpoint 3” are only
sent to the FI when parameter 2241 is smaller than parameter 2242. Otherwise, FI malfunctions can
result which can only be reset by switching off the FI. The maximum FI setpoint can, due to the above-
mentioned condition, not be set to zero by parameter 2242. Value “0” can; however, be set manually
on the FI.
Always set the parameter for the maximum frequency setpoint before setting the parameter for the
minimum frequency setpoint.
The parameters for the minimum and maximum frequency setpoint values cannot be changed during
operation. Changes made are only active following motor stop.
Switch the parameter set using parameter 2240 “Q analog setpoint 1” of the second respective
menu, SBM51 gateway (see Parameter 2240 “Q Analog Setpoint 1”, page 16).
The “remote” setpoint is only adopted by the SBM51/06 in automatic FI mode. When the FI is in
manual mode, the frequency inverter uses the “on-site setpoint”.
If necessary, the actual value is sent as the setpoint if no parameters are set (display “deleted”) in
parameter 2240 "Q analog setpoint 1". If a setpoint was set on-site on the frequency inverter, the
motor will continue to operate with the setpoints set on-site.
No setpoints are sent to the FI for actual value mode (parameter 2240 of the second respective menu)
. The FI runs with the on-site setpoints.
Function Following Interruption of the Danfoss Bus to the SBM51/06 (Using the VLT 6000 as
an Example)
Using the frequency inverter parameters “555 bus time interval” and “556 bus time interval”, you can
define which operating state the frequency inverter should adopt following bus interruption. “OFF” is
set as standard. The frequency inverter starts automatically as soon as the bus is ready for operation
again.
Refer to the Danfoss project planning documentation for information on settings for other types of FI.
SBM Behavior in the Event of an Error on the Switch Cabinet Bus (Diagnosis Function)
Resync functions are not yet supported by DDC3000 and DDC4000. Parameter 2240 “Q analog
setpoint 1” (Can_Resync_Time) in Resync/Diag menu is used for the diagnosis function (see page
12).
■When the Resync process is inactive on the DDC, the parameter 2240/31 [00] acts as a timeout
for SBM re-registration. FI operation is then interrupted.
■Parameter 2245 “Q digital setpoint 3” does not have any effect.

Digital Parameter Function
First Menu SBM51 Gateway (Odd-Numbered Addresses)
Set the FI motor enable via the parameter 2216 “Q digital setpoint 1”.
!
NOTICE
If the parameter 2216 “Q digital setpoint 1” has not been configured, it is not possible to enable the
motor in automatic FI mode. The motor remains at a standstill.
NOTE
When the value of parameter 2216 “Motor enable” changes, parameter 2254 can adopt a negative
value.
Motor freewheel stop is activated using parameter 2220 “Q digital setpoint 2”.
If the value of parameter 2220 is 1, the motor will coast down to a stop. This function has higher
priority than motor enable (parameter 2216). This function has no effect if parameter 2220 has not
been configured. This function is used in conjunction with the motor flying start function (see the
commissioning instructions from Danfoss).
Acknowledging Alarms
Set FI alarm acknowledgment via the parameter 2245 “Q digital setpoint 3”. Messages are always
acknowledged via the 0/1 edge of the assigned digital signal.
Second Menu SBM51 Gateway (Even-Numbered Addresses)
You can control the first two relay outputs with the SBM51/06 if the Danfoss frequency inverter is
equipped with relay outputs. Relay control is enabled via the parameter 2245 “Q digital setpoint 3”.
If the value of parameter 2245 is 1, the frequency inverter relay outputs can be controlled via the DDC
system.
Relay 1 is controlled via the 2216 “Q digital setpoint 1” parameter, relay 2 is controlled via the
parameter 2220 “Q digital setpoint 2”.
The values of the parameters 2216 and 2220 result in the following relay contact state:
■“0” or “deleted” →Relay is switched
■“1” →Relay is not switched
The DC brake of the frequency inverter is activated using parameter 2246 “Q digital setpoint 4”.
The value of parameter 2246 has the following effect on the state of the DC brake:
■“0” or “deleted” →The DC brake is switched off.
■“1” →The DC brake is active.

Project Planning: Frequency Inverter - SBM51/06
Commissioning (Using the VLT 6000 as an Example)
You can connect one to eight different types of Danfoss frequency inverter to theSBM51/06.
For commissioning, make the following settings on the frequency inverter:
■“FI Parameter 500, protocol: FC protocol (default setting)
■“FI parameter 501, bus address: set an address between 1 and 8
■“FI parameter 502, baud rate: 9600 Bd (default setting)
■“FI parameter 106, rated motor speed: is important when the speed is to be displayed on the
parameter “User-defined display 2253/01”.
■“FI parameter 006, unit of the “Free display”: 0, when the SBM51/06 is to perform configuration
for determining speed.
Refer to the commissioning instructions from Danfoss for further information.
Determining Speed (Using the VLT 6000 as an Example)
Parameter 2253/01 can be used to determine the speed if parameter 2252/01 “Absolute Speed” is
not supported by the FI type at hand. To do this, enter the nominal motor speed for FI parameter 005
(maximum value for user-defined display) on the frequency inverter. This value must completely
match the output frequency value.
FI parameter 2253/01 then outputs the speed.
If the SBM51/06 is to apply the speed via parameter 2253 “Analog actual value 7”, FI parameter
006 (unit of the scaled display) must be left at 0 (= default setting).
The unit from FI parameter 006 (nominal motor speed) is automatically set to rpm.
If the free display is to be used in another way, FI parameter 006 (unit of the scalable value) must be
set such that it is not equal to “0”. In this case, automatic configuration of the SBM51/06 remains
undone. The value displayed in the first respective software menu, SBM51 gateway, parameter 2253
“Analog actual value 7” is then a different value.
Malfunction messages
The parameter 2222 “Malfunction” of the first respective software menu, SBM51 gateway, is
generated in the frequency inverter using all bits from the frequency inverter alarm word.
Every alarm in the frequency inverter triggers the following actions:
■Sets the malfunction message contact and sets parameter 2222 “Malfunction” to “1”
■Switches the frequency inverter off
Acknowledge the alarm by pressing the reset button on the frequency inverter. Alternatively, there is
a way to acknowledge alarms via the DDC system (see page 19).
Warnings do not lead to a collective malfunction message.
Thermal Monitoring
Parameter 2224 “Digital actual value 2” of the second respective software menu, SBM51 gateway,
indicates motor thermal overload.
Thermal overload on the motor is determined either via monitoring of the electrical values of the motor
in the frequency inverter or by a thermistor installed in the motor. The motor protection type is set on
the FI (e.g. using parameter 117 for the VLT6000).
Thermal monitoring messages for the FI are reported in the collective malfunction message
parameter 2222 “Malfunction” of the first respective software menu, SBM51 gateway.
V-Belt Monitoring (Load shedding)
On the frequency inverter (e.g. using parameter 221 for the VLT6000), set the Lower current limit
that corresponds to load shedding due to a V-belt tear. Doing this makes it possible for parameter
2228 “Digital actual value 6” of the second respective software menu, SBM51 gateway, to display the
“V-belt malfunction” message correctly.
