5 Absolute encoder initialization
Absolute encoder initialization is the encoder clearing. This can be done by the set panel . After encoder clearing, switch off
the 24VDC power. The multi-rotation data has been cleared after switch on the control power again.
[5.1 Method for encoder clearing by set panel]
1) Change the drive parameters(set absolute system and RS-485 communication)
1. Turn on 24VDC power when not connected with the encoder. Change the parameters if no alarm occurs.
2. Change the Parameter No.4.0 Communication address from “initial value 1” to the expected communication address
No. . The setting range is from 1 to 32. Change Parameter No.8.0 Selection of host communication method from “initial value
0” to “1(RS-485 asynchronous serial communication)”. Change the parameterNo.257.0 from “initial value 0 (Incremental
system) to “1(Absolute system)”. For the parameter change method, refer to SV-E3 User Manual
「
5-6 Parameter setting
mode
」
3. Refer to SV-E3 User Manual
「
5-8 Parameter saving mode
」
to save the parameters. If not save the parameters, the
changed parameters will be invalid when power ON next time.
4. Switch off the control power (24V).
2) Restart the power
1. Refer to
「
4-1 Battery box cable installation
」
to connect the battery box to the encoder and turn on the control power.
2. When restart the control power, the encoder error (
) will display on the set panel. Simultaneously, the
multi-rotation data error ( Er r . 20) and encoder low-voltage error occur (Err. 21).
3) Move to the home position
Move the axis which does not set the home position to the home position. When moving to the home position by manual is
possible, move it to the home position. This should be done at servo ON. Move them around the home position and perform
the operation of 4) to 6), then 4) to 5).
4) Operating the encoder clearing by set panel
1. Make the panel display
. When display
, press the MODE(
) button for seven times.
2. Refer to the following figure to press the SET (
) button once and UP(
) button once to display
.
3. Press the SET(
) button to display
.
4. After long-press the LEFT(
) button to show
,
displays and the multi-rotation data
become 0.
5.Switch off the control power. Until now, the absolute encoder initialization has been completed.
The operation procedures to have the encoder clearing by set panel are shown blow.
Operate the encoder clearing at servo OFF. If servo ON, the alarm
will occur.
