2.5 Connection of Power Supply
2.5.1 Power Supply Input Connection
(1) When using one power supply unit
Install the unit so that the total wiring length of DC power supply terminals TE2 (L+, L-) is 1500mm or less. Large-
capacity spindle drive units, in particular, should be installed adjacent to the power supply unit which they control.
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 circuit protector, 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.
CAUTION
1. The power supply unit is equipped with 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.
3. Connect the power supply unit's CN4 connector with the spindle drive unit of the maximum capacity. If there is no spindle
drive unit, connect to the servo drive unit which is the unbalance axis.
4. When installing the units dispersed install the spindle drive unit adjacent to the power supply unit, and connections for
other drive units should be such that the total TE2 wiring length is 1500mm or less.
