Maintenance
11.Replace the DCS..B option, see chapter "Basic procedure for installing/removing an
option card (MDX61B, sizes 1 – 7)" (page 37).
12.Switch the DC 24 V supply voltage back on.
13.Perform steps 4 to 7 again.
14.Send the saved configuration to the DCS..B option. Load the configuration data from
the PC file ([Communication] menu item, [Open…] button) and send it to the DCS..B
option. To do so, go to the [Communication] menu and press the [Send configuration]
button.
15.Switch to "RUN" mode ([Communication] menu item, [Run mode] button).
16.Check the current CRC value against the value you have written down in the first
step.
You can read off parameter P554 CRC DCS using the DBG60B keypad or the
MOVITOOLS
®
MotionStudio software.
17.If the CRC is identical, plug terminal X17 onto MOVIDRIVE
®
B again.
18.Switch on the power supply voltage.
8.3.3 Replacing the SSI absolute encoder
The following cases are distinguished when replacing an SSI absolute encoder:
Position process-
ing not active
Do the following to replace an SSI absolute encoder without active position process-
ing in the DCS..B option:
1. Before replacing the encoder, switch off the mains voltage and the DC 24 V supply
voltage.
2. Remove terminal X17 from MOVIDRIVE
®
B to prevent MOVIDRIVE
®
B from
enabling the motor unintentionally.
3. Replace the encoder in the application. Make sure that the encoder type is the same.
4. Switch the DC 24 V supply voltage back on.
5. Connect the parameter setting and diagnostic interface X87 of the DCS..B option
with your PC, see chapter "Communication and establishing a connection"
(page 76).
6. Start the MOVISAFE
®
Assist/Config software and establish a connection.
7. Use the SCOPE function to check the transmitted position and velocity of your
encoder.
8. Re-connect terminal X17 to MOVIDRIVE
®
B.
9. Switch on the power supply voltage.
10.Validate your entry.
Position processing in the DCS..B option Application
Not active Simple speed monitoring:
• No encoder offset necessary
Active Positions are monitored:
• Necessary to adjust/recalculate the encoder offset
(usually with rotative encoders)
