Supplement
1. The C-axis control function is connected to the CN7 connector.
2. When using both the C-axis control function and orient ation function, two cables (two-wire cable) are
connected from the detector.
3. The orientation signal connected to CN5 or CN6 can be connected to the NC with the differential
output from the CN8 connector.
CAUTION
The shield of spindle detector cable is not FG. Do not ground.

2-5 Connection of power supply
CAUTION
1. Make sure that the power supply voltage is within the specified range of each
unit. Failure to observe this could lead to damage or faults.
2. For safety purposes, always install a No-fuse breaker (NFB), and make sure
that the circuit is cut off when an error occurs or during inspections.
3. The wire size will differ according to each drive unit capacity.
4. For safety purposes, always install a magnetic contactor (contactor) on the
main circuit power supply input. Large rush currents will flow when the power
is turned ON.
5. A semiconductor element is used in the power supply unit's magnetic contact
drive circuit, and a surge absorber is installed to protect the element.
Therefore, a leakage current of approx. 15mA is passed. Confirm that the
exciting coil in the magnetic contact will not function at 15mA or less.
