Whether the speed range switching control function is used (Set to 1.)
(CNC software option is necessary.)
6514#3 3014#3 4014#3
Function for checking the statuses of the magnetic contactors for both high–speed
range and low–speed range
6519#4 3019#4 4019#4
Function for checking the speed detection signal when switching from high–speed
range to low–speed range
6523 3023 4023 Speed detection level
6924 3304 4160 Hysteresis for the speed detection level
D Use an electromagnetic contactor for speed range switching whose
capacity is suited for the spindle amplifier module
For the sake of reference, the table below lists the model ratings of
electromagnetic contactors made by Fuji electric and Telemechanic.

D In order to suppress electrical noise generated at switching in the
electromagnetic contactor for speed range switching, use a surge
absorber containing resistor and capacitor.
D Setting the machine ready signal (MRDYA)
For the purpose of safety, use two signals in the sequence that makes
the system operable. These are the emergency stop signal (
*
ESPA) and
machine ready signal (MRDYA). Set the machine ready signal
(MRDYA) to 1 to allow operation of the machine.
D When conducting rigid tapping, set the desired speed range in advance
and do not perform switching.
Accordingly, when conducting rigid tapping, although the speed
detection signal (SDTA) will be output from the spindle amplifier, be
sure that this signal is ignored.
