These parameters set the deceleration constant for the position coder
method spindle orientation. The value to be set can be calculated the
following formula.
Spindle orientation
deceleration constant
= 120 (Acc/Dec time constant) 0.8
Acc/Dec time constant (min
–1
/sec) is the setting data of PRM4069 to 4072
(Series 16).
