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.
2-5-1 Power supply input connection
(1) When using one power supply unit
Install the drive units so that the distance between power supply unit and spindle drive unit will be
3cm or less.

CAUTION
1. The power supply unit is a power supply regenerative type converter; an AC
reactor is surely installed in the power supply line.
2. When connecting to the TE3 terminal, connect to the power supply side
(primary side) of the AC reactor.
