(4) Enter the value recorded in (1) into “Axis-specific parameter No. 83, Absolute synchro slave-axis
initialization cancellation” for the slave axis.
Transfer the parameter data to the controller, write to the flash ROM, and then restart the
controller (software reset).
(5) Set the home preset value to align the coordinate values between the master axis and slave axis.
[1] With the servo still off, read the current positions displayed for the master axis and slave axis if
the controller’s 7-segment display shows “rdy.”
(If an “Error No. C74, Actual-position soft limit over error” generates, reset the error. Once “rdy”
is displayed, you can read the current positions displayed.)
* When the servo is turned on, “Error No. D0A, Driver overload error,” “Error No. C6B,
Deviation overflow error,” “Error No. CA5, Stop deviation overflow error,” etc., will generate.
[2] Perform the following calculation.
Axis-specific parameter No. 12, Home preset value for the slave axis [0.001 mm] + ((Current
master axis position displayed [mm] – Current slave axis position displayed [mm]) x 1,000)
In this example, the above formula should read as follows:
