Abstract In the firmware version V4.4 of the SINAMICS G120 Control Units (CU230P-2, CU240B-2 and CU240E-2), the function of the analog inputs (p0756 = 3: "unipolar current input, monitored (+4 mA ... +20 mA)") is incorrect. As soon as parameter p0756 is set to 3, then fault message F03505 (N, A) "CU: analog input wire breakage" is generated, independent of the input current at the corresponding analog input; this means that the fault message is also generated if the input current at analog input is between 4 and 20 mA. Fault F03505 cannot be acknowledged in this case.
Instruction
The function p0756[0...1] = 3: "unipolar current input, monitored (+4 mA ... +20 mA)" of the analog inputs can be emulated using free function blocks (FFB) and an "external fault" message. The analog inputs are then set to: "unipolar current input (p0756 = 2 / 0 mA ... +20 mA)", and the monitoring for 4 mA is realized with FFB.
The parameter settings as follow:

***If parameter p2106[0] is already being used for another purpose, then parameter p2107[0] or p2108[0] can be used:
p2107[0] = r20232.0 -> F07861: External fault 2
p2108[0] = r20232.0 -> F07862: External fault 3
Result If the current input value of 4 mA is fallen below, instead of fault message F03505 "Analog input wire breakage", an message "external fault 1", 2 or 3 (F07860, F07861 or F07862) is initiated.
The IOP firmware (IOP = Inteligent Operator Panel) is released for customer upgrading using Windows XP (Entry-ID: 43896115).
However, if an update of the IOP is attempted via an Enhanced USB Port (USB 2.0) then the Application loading may fail.
Additionally, if other equipment is connected to the computer via USB then the update process can fail.
If problems occur then first try disconnecting other USB devices
How do I tell if I am connected via an Enhanced USB Port?
Goto:
Start -> Settings -> Control -> System
Click Hardware tab.
Then Click Device Manager
When you see the Device Manager Window select View click Devices by connection
Normally your USB Device is shown connected off the PCI Bus
Look for Something that Says USB. It will normally say USB Universal Host Controller or USB Enhanced Host Controller.
Example
Fig. 01
INCORRECT Notice the IOP Connected to the USB 2.0 Enhanced Host. This will not work properly.
This normally happens when the Laptop is connected via a Docking Station or not directly connected to a USB port on the Laptop.
Fig. 02
CORRECT
The IOP is connected direct to USB Port on Laptop.
Notice now that the IOP is connected to the USB Universal Host Controller.
In some cases you may need to remove your Laptop completely from the Docking Station as this could affect the connections internally via the USB Port Device. Normally this problem occurs only with Laptop PC’s from Siemens Fujitsu but it could also exist in other Laptops.

Why does the speed “jumps” at low frequencies when ramping down?
Why does my motor not ramp down to 0 Hz even if torque limit is set to 0?
The motor temperature shown in r0035 is implausible, what can I do?
This product information sheet describes the behavior of the below mentioned inverters (Firmware version V3.1), that is not described in the associated documentation, edition 06/2007, Firmware version 3.1.
SINAMICS G120
SINAMICS G120D
All inverters:
If in sensorless vector control (SLVC) one of the following problems appears …
•
motor does not ramp down
•
setpoint jumps at low frequencies at ramp down
•
motor does not ramp down to 0 Hz even if torque limit is set to 0
•
the calculated motor temperature (P0621 > 0) shown in r0035 is implausible
… this can be caused by faulty values for both, stator and motor cable resistance.
Try the following to solve the problem:
•
disconnect the motor from the feeder cable
•
measure the stator resistance and the motor cable resistance with an ohmmeter or better with a wheatstone bridge
•
put the values in P0350 (stator resistance) and P0352 (cable resistance)
•
then perform "calculation of motor parameters" again with P0340 = 3.
If you don’t obtain feasible values when measuring the stator resistance, use the equivalent circuit data of the motor (this can be can be provided by the motor manufacturer) and write it into the respective parameters (fig 6.1 in Function Manual) or reduce the stator resistance in 5 % steps and perform "calculation of motor parameters" again with P0340 = 3.
Information on the motor parameters:
P0350 =
stator resistance (phase)
P0354 =
rotor resistance
P0356 =
stator leakage inductance
P0358 =
rotor leakage inductance
P0360 =
main inductance
For frequency inverter operation (the motor is connected to a drive inverter and not to the line supply) then the motor is normally connected in the Y circuit configuration.
In this case, the actual values determined using the motor identification (= Mod-ID / P0340) can be used. If an incorrect measurement is made by the motor data identification routine then users should measure this data or take the data from the motor data sheet (this is available from the motor manufacturer) and transfer the data into the particular parameters.
If the motor is connected in delta, then the SW star motor model parameters are smaller than the motor model parameters of the star connected motor. This means, the equivalent circuit data need to be converted before writing to the motor model parameters.
The SW looks at the motor as a black box, which is connected in star!
Therefore is valid:
G120 in Sternschaltung
G120 in Dreieckschaltung (= Sternwert / 3)
P350 = R1 k
P350 = R1 k / 3
P354 = R2k’
P354 = R2k’ / 3
P356 = X1 streu / (2*PI*50)
P356 = (X1 streu / (2*PI*50)) / 3
P358 = X2streu’ / (2*PI*50)
P358 = (X2streu’ / (2*PI*50)) / 3
P360 = X1 H / (2*PI*50)
P360 = (X1 H / (2*PI*50)) / 3
P352 = calculated or measured per-phase value for the cable resistance. This value is the same for a star or delta connected motor, since the delta connection of the motor does not influence the cable resistance. Please note that the “cold” (e.g. R1k) values need to be used.
The following applies to the other motor parameters:
The values of the motor rating plate - applicable for the particular connection type - should be parameterized.
P0304 =
rated motor voltages
P0305 =
rated motor current
P0307 =
rated motor power
Fail-safe inverters: If SS1 or SLS is activated then a short STO signal is signaled in the safety status word r9772. This STO pulse has no influence on the SS1 or SLS function and can be ignored.
CU240S PN: If in HW config of STEP 7 a different telegram type is selected from the telegram type selected in P0922 in the inverter, the inverter trips with F00452 (belt failure). If this fault occurs then check the telegram set in HW config and P0922.
The automatic restart function (P1210) cannot be used in conjunction with PROFInet. If the drive inverter is to resume operation after a power failure then an ON command must be entered from the parameterized sources.
Power Modules PM260:
"Motor Temperature Identification" (P0621) should not be used with Power Modules PM260. The motor temperature is still monitored according the settings in P0601.

What are the differences between the parameters of the MICROMASTER 4 and those of the SINAMICS G120?
The parameter structure of the SINAMICS G120 is based on its predecessor - the MICROMASTER 4th Generation – and represents a consequential further development.
Although the parameter structures have remained the same - the G120 offers users many new functions. The implementation and handling of the new functions means that certain changes had to be made to some parameters.
The main differences are therefore also associated with the fact that the G120 has a modular design. The G120 has different types of Control Modules (CUs) that have different functions and communication interfaces.
For instance the CU240S DP-F safety module is configured for PROFIBUS-DP and also includes safety functionality. However, there is no possibility of setting USS for the RS485. For the CU240S module the opposite applies: This module does not have any safety functionality and has no possibilities of making settings for a fieldbus; however, this module can address a COM link via USS.
All of the changes to the parameters of the various G120 control modules with firmware release 2.0 in comparison to those of MICROMASTER 440 FW 2.10 are provided in the attached file.
The parameter structure of the SINAMICS G120/G120D is based on that of its predecessor - the MICROMASTER 4th generation – and represents a consequential further development.
The parameter structures of the MM4 and G120/G120D have essentially remained the same. When compared to the MM4, the G120/G120D offers users far more functions. The realization and handling of these new functions is associated with certain changes to parameters that have had to be made.
An essential change is also due to the fact that the G120/G120D has a modular structure. For G120/G120D, there are various types of control modules (CUs) that have different functions and communication interfaces.
A comparison between all of the parameters of the last software version of MM440 (FW2.11) and all of the parameters of the current software versions of all G120 and G120D control modules is provided in the attached Excel List.
The Excel List is described in detail in the PDF file and information is given how you can handle the Excel List.
The Excel List contains all of the parameters of the MM440 FW2.11 and the following Control Units of the G120/G120D:
