3. Execute initialization.
Initialization can be executed either from the data area interface using a lad-
der program or by using the Teaching Box.
Using a Ladder Program
Turn ON the ABS Initialization Bit in manual mode when the Busy Flag is OFF.
Leave this bit ON until the Busy Flag turns ON.
Using the Teaching Box
Select 5. ABS INIT SET from the extension mode menu, and execute proces-
sing.
Note 1. Execute initialization when absolute data is within the range of ±32767
pulses. Otherwise, an error will occur.
2. Refer to 6-5 Interface Bit Specifics for details on a timing chart and ladder
program example of the ABS Initialization Bit. Refer to the Teaching Box
Operation Manual for details on Teaching Box operation.
ABS Initialization will reset the current position to zero and store the absolute
data in the machine parameter area as the Absolute Encoder initial setting.
Note After ABS Initialization is completed, back up the system parameters using the
MC Support Software.
Use the flash memory write function of the MC Support Software or Teaching
Box to write the settings to the flash memory.
The Absolute Encoder initial settings can be displayed using the MC Support
Software, but they cannot be changed.
Do not execute ABS Initialization while system parameters are being down-
loaded. Otherwise, the Absolute Encoder initial settings will not be stored prop-
erly.
Do not execute ABS Initialization within one second after the main power supply
or control power supply to the Servodriver is turned ON.
7-7 ABS Soft Reset
ABS Soft Reset is used to perform fine adjustment of the origin position in servo
lock status after ABS Initialization has been executed.
Unlike ABS Initialization, the Absolute Encoder does not have to be set up.
Procedure
1, 2, 3... 1. Check that the pin 1 of the DIP switch on the rear of the MC Unit is set to OFF.
If this pin is set to ON, an error will occur when ABS Soft Reset is executed.
2. Execute ABS Soft Reset.
As is the case with ABS Initialization, processing can be executed either
from the data area interface by using a ladder program or by using the
Teaching Box.
Using a Ladder Program
Turn ON the ABS Soft Reset Bit in manual mode when the Busy Flag is OFF.
Leave this bit ON until the Busy Flag turns ON.
Using the Teaching Box
Select 6. ABS SOFT RSET from the extension mode menu, and execute pro-
cessing.
Note 1. Execute ABS Soft Reset when the current position is within the range of
±32767 pulses. Otherwise, an error will occur.
2. Refer to 6-5 Interface Bit Specifics for details on a timing chart and ladder
program example of the ABS Soft Reset Bit. Refer to the Teaching Box
Operation Manual for details on Teaching Box operation.
ABS Soft Reset can be executed regardless whether the servo lock is applied or
released.
