Use an external one-rotation signal switch (proximity switch) that
satisfies the specifications indicated below.
(a) DC two-wire proximity switch
Item Specification
Supply voltage
24 VDC
±1.5 V
(24 VDC is fed from the spindle amplifier module.)
Response frequency 400 Hz or higher
Load current 16 mA or higher
Residual voltage 4 V or higher
Supply (leakage) current 1.5 mA or lower
(b) DC three-wire proximity switch
Item Specification
Supply voltage
24 VDC

(24 VDC is fed from the spindle amplifier module.)
Response frequency 400 Hz or higher
Load current 16 mA or higher
Residual voltage 4 V or higher
Supply current 50mA or lower
NOTE
The location where a proximity switch signal occurs
depends on the temperature. So, consider the
ambient temperature when selecting a proximity
switch.
