8.2 MDS-B-SPJ2
For parameters marked with a (PR) in the tables, turn the NC power OFF after setting. The parameters
will be valid after the power is turned ON again.
The valid spindle parameters will differ according to the motor and amplifier type. Follow the
correspondence table given below, and set the correct parameters.
The spindle parameter setting and display method will differ according to the NC being used, so refer to
Instruction Manual for each NC and the following spindles.

CAUTION
!
Do not make remarkable adjustments or changes of the parameters as the operation may
become unstable.
