Do the following to replace an SSI absolute encoder with active position processing
in the DCS21B/31B 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 DCS21B/31B
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. If the position is identical with the position in the application, no adjustments
are necessary and you can proceed with step 16.
8. If the position is not identical, open the original program in the MOVISAFE
®
Assist/Config software. All subsequent changes cause the CRC to be calculated
again.
9. Open the encoder screen and overwrite the entered encoder offset with "0".
10.Save this new configuration under another name.
11.Send the new configuration to the DCS21B/31B option.
12.Use the SCOPE function to check the transmitted position of your encoder.
13.Open the encoder screen again. Use the offset calculation wizard to calculate the
new offset of your replaced encoder for the application.
14.Send the new, adjusted configuration to the DCS21B/31B option.
15.Use the SCOPE function to check the transmitted position and velocity of your
encoder again.
16.Re-connect terminal X17 to MOVIDRIVE
®
B.
17.Switch on the power supply voltage.
18.Validate your entries.
Replacing the SSI
absolute encoder
ATM60
Do the following to replace the SSI absolute encoder ATM60 from Sick-Stegmann with
active position processing 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.
INFORMATION
If you use the encoder values of MOVIDRIVE
®
B via the backplane bus, you can make
the offset entries in MOVITOOLS
®
MotionStudio.
In any case, check the transmitted position and velocity of your encoder using the
SCOPE function of the MOVISAFE
®
Assist/Config software.
