3 Preparation
3.1 How to get and install SCM Firmware Updater
The latest version of SCM Firmware-Update can be found on the web at:
Link: http://go.sew/os/dud/?tab=software&search=SCM-B
The SCM Firmware Updater always contains only the latest firmware version. Therefore,
always download the latest version from the SEW homepage. The version of the firmware
contained is displayed when the program file is started before the update process.
3.1.1 Backup of drive data
The SCM Firmware Updater saves the device data before the new firmware is installed and
will be restored again after the update process.
3.1.2 Installation of the SCM Firmware-Updater
If the SCM Firmware Updater was not previously installed on the computer, proceed as
follows:
1. Download the SCM Firmware Updater to your Windows device.
2. Unpack the ZIP archive
3. Install the USB device driver as follows:
Installing the device drivers
1. To install the drivers, run the device driver installation wizard "dpinst64.exe" and
follow the instructions of the application.
2. If there is already a more recent driver on the PC, the wizard will not overwrite it and
will display the installed drivers in the summary.

3.2 Establish connection with the drive
INFOR MATION
The controller has a separation between the voltage potentials and the functional ground
(housing). In most computers, GND is connected to the housing. To prevent damage to
your computer, e.g. due to compensating currents, we always recommend the use of a
USB isolator and an unshielded USB cable.
Recommendation:
USB adapter and micro USB cable
SEW‑EURODRIVE recommends using the following USB adapter and cable, which can
be ordered directly from the manufacturer.
Delock USB Isolator mit 5kV Isolation
62588
Goobay USB-A -> micro USB, 2,0 m
38660
After you have put your machine in STO, you can start connecting the controller and your
computer.
Connect the controller to your computer via a micro USB cable. You can connect both
service ports (X31_1 and X31_2) to your computer at the same time or update one by one.
The SCM Firmware Updater will automatically detect both drives and update them with the
new firmware one by one.
The device must be powered for the update process.
WAR NING!
Accidental restart of the machine or unexpected movement.
An unpredictable function of the drive during or after the update process may endanger
your machine.
•Put the controller into STO and the machine into safe state.

Firmware Update

Manual – Decentralized controller of type SCM 11
4 Firmware Update
1. Start the "SCM-Firmware-Update.exe" and accept admin query if necessary.
−The updater shows the contained firmware version.
−Then the detected drives with its serial numbers and current version of firmware
are displayed. If the firmware on the drive is newer or equal to the updater version,
no update will be performed.
−If no device was found, check the power supply and the USB connection and start
die application again.
2. To start the update process, enter the password and confirm with <Enter>: scm
NOTIC E !
Do not under any circumstances disconnect the power supply, the USB connection or exit
the program during the update!
The inverter may be irreparably damaged.
•Ensure a stable power supply and do not move the devices during the update.
3. The update process starts:
−Backup of the drive data to hard disk
−Update process
−Restoring drive data back to drive
−The successful completion of the update process reported to you in the program.
−When requested, press <Enter> in the firmware updater to close the program.
4. After the completion of the update process, it is mandatory to restart the controller by
disconnecting the power supply.

5 After the update process
After a successful firmware update, we recommend the following steps depending on the
used motor encoder to ensure correct operation of your machine.
5.1 Resolver
5.1.1 Switching on the temperature monitoring
If the temperature monitoring is used, the temperature monitoring may have to be switched
on.
For this purpose, the parameter "CA[60]" must be set to the value 1 via the terminal (Chap-
ter 5.4.1) see the overview in Chapter 5.4.
Setting jumpers
Up to now, the motor temperature has not been monitored. The jumpers S1 and S2 must
be plugged in position 3 (resolver TF monitoring).
If you have not connected the motor temperature sensor or have inserted the jumpers in-
correctly, you will get an error message after the update.
Plug-in position of the jumpers (Extract from operating instructions)
S1 S2
5.1.2 Disabling the temperature monitoring
If the temperature monitoring is not used or the analog input is used for other purposes,
the temperature monitoring must be switched off.
For this purpose, the parameter "CA[60]" must be set to the value 0 via the terminal (Chap-
ter 5.4.1) see the overview in Chapter 5.4.
5.2 EnDAT 2.2 Encoder
5.2.1 Switching on the temperature monitoring
If the temperature monitoring is used, the temperature monitoring may have to be switched
on.
For this purpose, the parameter "CA[60]" must be set to the value 9 via the terminal (Chap-
ter 5.4.1) see the overview in Chapter 5.4.

After the update process
5
Manual – Decentralized controller of type SCM 13
5.2.2 Disabling the temperature monitoring
If the temperature monitoring is not used or the analog input is used for other purposes,
the temperature monitoring must be switched off.
For this purpose, the parameter "CA[60]" must be set to the value 0 via the terminal (Chap-
ter 5.4.1) see the overview in Chapter 5.4.
5.3 Proceeding for machines/projects with existing parameter set
If there is already an existing parameter set for the decentralized controller type SCM that
you load on your SCM during controller startup, the new properties may be disabled. Check
your parameter set or your IEC project and adapt it if necessary.
To switch temperature monitoring on or off, check the line in the parameter set that starts
with "CA[60]=[VALUE]" and check/change the value after the equal sign.
Possible values are: 0, 1, 8, 9, 10 and 11 - see chapter 5.4
5.4 Meaning of parameter CA[60] (related bits)
Parameter CA[60] describes the encoder and temperature monitoring in combination.
The parameter is handled bit-wise. The following bits are relevant for the configuration:
Bit 0 switches on the temperature monitoring
Bit 1 switches the "Gray code" for the SSI sensor
Bit 3 switches on a serial encoder (EnDat 2.2 / SSI)
This results in the following values:
CA[60] Value Function
0 Configuration resolver, temperature monitoring switched off
1 Configuration resolver, temperature monitoring switched on
8 Configuration EnDat or SSI binary, temperature monitoring switched off
9 Configuration EnDat or SSI binary, temperature monitoring switched on
10 Configuration SSI Gray code, temperature monitoring switched off
11 Configuration SSI Gray code, temperature monitoring switched on

5.5 Switch-Off Thresholds XT[x].
The switch-off thresholds can also be read out and adjusted in the terminal. Proceed as
described in chapter 5.4.1.
With the added temperature monitoring, the switch-off thresholds of the overtemperature
or undertemperature of the corresponding encoder configuration are added. These param-
eters are described in the following with the corresponding default values.
Switch-Off Thresholds
Parameter Description Default value
XT[5] EnDat 2.2 overtemperature limit 4368 110°C
XT[6] Resolver or SSI overtemperature limit 1768 140°C
