(2) Wiring
CAUTION
Correctly and securely perform the wiring. Failure to do so could lead to runaway of the motor.
Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of
the drive unit.
Correctly connect the output side of the drive unit (terminals U, V, W). Failure to do so could
lead to abnormal operation of the motor.
Always install an AC reactor for each power supply unit.
Always install an appropriate breaker for each power supply unit. Breakers cannot be shared
by several units.
Direct application of a commercial power supply to the motor could cause burning. Always
connect the motor to the drive unit's output terminals (U, V, W).
When using an inductive load such as a relay, always connect a diode as a noise measure
parallel to the load.
When using a capacitance load such as a lamp, always connect a protective resistor as a noise
measure serial to the load.
Do not reverse the direction of a diode which
connect to a DC relay for the control output
signals to suppress a surge. Connecting it
backwards could cause the drive unit to

Do not connect/disconnect the cables connected between the units while the power is ON.
Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could
cause the cable to fall off while the power is ON.
When using a shielded cable instructed in the connection manual, always ground the cable with
a cable clamp, etc.
Always separate the signals wires from the drive wire and power line.
Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to
the system.

(3) Trial operation and adjustment
Check and adjust each program and parameter before starting operation. Failure to do so could
lead to unforeseen operation of the machine.
Do not make remarkable adjustments and changes as the operatio n could become unstable.
The usable motor and unit combination is predetermined. Always check the models before
starting trial operation.
If the axis is unbalanced due to gravity, etc., balance the axis using a counterbalance, etc.
The linear servomotor does not have a stopping device such as magnetic brakes. Install a
stopping device on the machine side.
(4) Usage methods
Install an external emergency stop circuit so that the operation can be stopped and power
shut off immediately.
Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the unit
or motor.
Unqualified persons must not disassemble or repair the unit.
CAUTION
Never make modifications.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the unit
could be affected by magnetic noise.
Use the unit, motor and regenerative resistor with the designated combination. Failure to do so
could lead to fires or trouble.
The brake (magnetic brake) assembled into the servomotor are for holding, and must not be
used for normal braking. Do not apply the brakes in the servo ON state. Doing so will lead to a
drop in the brake life. Always turn the servo OFF before applying the brakes.
There may be cases when holding is not possible due to the magnetic brake's life or the
machine construction (when ball screw and servomotor are coupled via a timing belt, etc.).
Install a stop device to ensure safety on the machine side.
After changing the programs/parameters or after maintenance and inspection, always test the
operation before starting actual operation.
Do not enter the movable range of the machine during automatic operation. Never place body
parts near or touch the spindle during rotation.
Follow the power supply specification conditions given in the separate specifications manual for
the power (input voltage, input frequency, tolerable sudden power failure time, etc.).
(5) Troubleshooting
If a hazardous situation is predicted during power failure or product trouble, use a servomotor
with magnetic brakes or install an external brake mechanism.
Use a double circuit configuration
that allows the operation circuit for
the magnetic brakes to be operated
even by the external emergency
stop signal.

Always turn the input power OFF when an alarm occurs.
Never go near the machine after restoring the power after a power failure, as the machine
could start suddenly. (Design the machine so that personal safety can be ensured even if the
machine starts suddenly.)
(6) Maintenance, inspection and part replacement
Always backup the programs and parameters in the CNC device before starting maintenance
or inspections.
The capacity of the electrolytic capacitor will drop over time due to self-discharging, etc. To
prevent secondary disasters due to failures, replacing this part every five years when used
under a normal environment is recommended. Contact the Service Center or Service Station
for replacement.
Do not perform a megger test (insulation resistance measurement) during inspections.
If the battery low warning is issued, back up the machining programs, tool data and
parameters with an input/output unit, and then replace the battery.
Do not short circuit, charge, overheat, incinerate or disassemble the battery.
The heat radiating fin used in the 37kW and smaller unit contains substitute Freon as the
refrigerant.
Take care not to damage the heat radiating fin during maintenance and replacement work.
(7) Disposal
Do not dispose of this unit as general industrial waste. The
37kW and smaller unit with heat radiating fin protruding from
the back of the unit contains substitute Freon. Do not dispose
of this type of unit as general industrial waste. Always return
to the Service Center or Service Station.

2. Wiring and Connection
DANGER
1. Wiring work must be done by a qualified technician.
2. Wait at least 15 minutes after turning the power OFF and check the voltage
with a tester, etc., before starting wiring. Failure to observe this could lead to
electric shocks.
3. Securely ground the drive units and servo/spindle motor with Class 3
grounding or higher.
4. Wire the drive units and servo/spindle motor after installation. Failure to
observe this could lead to electric shocks.
5. Do not damage, apply forcible stress, place heavy items on the cables or get
them caught. Failure to observe this could lead to electric shocks.
6. Always insulate the power terminal connection section. Failure to observe
this could lead to electric shocks.
1. Correctly and securely perform the wiring. Failure to do so could lead to
runaway of the servo/spindle motor.
2. Do not mistake the terminal connections.
Failure to observe this item could lead to ruptures or damage, etc.
3. Do not mistake the polarity ( + ,
– ). Failure to observe this item could lead to
ruptures or damage, etc.
4. Do not mistake the direction of the diodes for the surge absorption installed
on the DC relay for the motor brake and contactor (magnetic contactor)
control. The signal might not be output when a failure occurs.
Drive uni t
COM
(24VDC)
CAUTION
Control output signal
RA
5. Electronic devices used near the drive units may receive magnetic
obstruction. Reduce the effect of magnetic obstacles by installing a noise
filter, etc.
6. Do not install a phase advancing capacitor, surge absorber or radio noise
filter on the power line (U, V, W) of the servo/spindle motor.
7. Do not modify this unit.
8. The half-pitch connector (CN1A, etc.) on the front of the drive units have the
same shape. If the connectors are connected incorrectly, faults could occur.
Make sure that the connection is correct.
9. When grounding the motor, connect to
the protective grounding terminal on the
drive units, and ground from the other
protective grounding terminal.
(Use one-point grounding)
Do not separately ground the connected
motor and drive unit as noise could be
generated.

Main circuit power supply input terminal
Connect a 3-phase 380 to 480VAC, 50/60Hz power supply.
Control circuit power supply input terminal
Connect a single-phase 380 to 480VAC, 50/60Hz power supply.
Connect the same power supply phase for L11 and L12, and L21 and
L22.
Contactor control terminal
The MC1 terminal has the same phase as L21. Connect to a different
phase than the phase connected to L21. (Connect MC2 with L21.)
Servo/spindle motor power output terminal
The servo/spindle motor power terminal (U, V, W) is connected.
Servo motor power output terminal (L-axis/M-axis)
The servo/spindle motor power terminal (U, V, W) is connected.
Grounding terminal
The servomotor/spindle motor grounding terminal is connected and
grounded.
1. Always use one AC reactor per power supply unit.
Failure to observe this could lead to unit damage.
CAUTION
2. When sharing a breaker for several power supply units, of a short-circuit
fault occurs in a small capacity unit, the breaker could trip. This can be
hazardous, so do not share the breaker.
3. Be sure to use the breaker of proper capacity for each Power Supply Unit.

2. Wiring and Connection
2-2-3 How to use the control circuit terminal block (MDS-CH-SP-750)
The control power for the 75kW spindle unit is not connected to the terminal block, so wire according to
the following instructions.
<1> Treatment of wire end
Single wire: Peel the wire sheath, and use the wire.
(Wire size: 0.25 to 2.5 mm
2
)
Stranded wire: Peel the wire sheath, and then twist the core wires.
Take care to prevent short circuits with the
neighboring poles due to the fine strands of the core wires. Solder plating onto the
core wire section could cause a contact defect and must be avoided. (Wire size:
0.25 to 2.5 mm
2
)
Use a bar terminal and bundle the strands. (Made by Phoenix contact)
Length to peel
Approx. 10mm

0.25 24
0.5 20
0.75 18

1.5 16
2.5 14
<2> Connection method
Insert the core wire section of the wire into the opening, and tighten with a screwdriver so that the
wire does not come out. (Tightening torque: 0.5 to 0.6 N•m) When inserting the wire into the
opening, make sure that the terminal screw is sufficiently loose. When using a wire that is 1.5 mm
or less, two wires can be inserted into one opening.
