SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Eeospcspl001
The controller described in this manual consists of electric parts and units.
To prevent accidents and also failure and burning of electric parts and units due to improper inter-
connection of them and also connection of power cables, please read the manual carefully and
strictly observe the items indicated below.
(1) Before connecting or disconnecting/removing a unit, shut off all power supplies and discharge
parts in units which have been charged. Otherwise, injury, or failure or burning of a unit may
occur.
(2) Check the specifications of the power supply to be connected. Failure or burning of a unit may
occur if power supply voltage does not match the power requirements of the unit or if the polar-
ity is incorrect.
(3) Connect inputs and outputs of a unit correctly. If they are connected incorrectly, failure or burn-
ing of a unit may occur.
(4) Always ground units and connect the P.E. earth cable of the electric cabinet. Otherwise, electric
shock may cause if leakage occurs.
(5) Insert an over current protection device (breaker, fuse) to the power supply which is connected
to units. Otherwise, cables or units may be burnt or fire may be cause due to short circuit.
(6) When manufacturing cables used for connecting units, make sure that the size of cables
matches the carrying current. Especially, power cables must be manufactured carefully. If the
current capacity of the cable is insufficient, the cable may be heated to be burnt or fire may be
caused.
(7) The electric cabinet and the operation box where units are installed must be water-and dust-
proof construction. Otherwise, injury, or failure or burning of a unit may occur.
(8) Make sure to use a thermostat incorporated in motors and units to protect devices. Otherwise,
devices may be burnt or fire may be caused.
The following warning indications are used in this manual to draw special attention to information of
particular importance.
Keep this manual carefully so that you can read it whenever you need the information in this man-
ual.
The contents of the manual may be changed due to improvements of the product.

Eeospcsa1001
Okuma motion control system (MCS) consists of an inverter unit and a DC power supply unit.
This section describes the maintenance and inspection methods for the inverter unit (to be referred
to as MIV unit, hereafter).
1. System Configuration
Eeospcsa1002
MIV unit is an inverter unit that drives spindle motors and axis drive motors. Connection of MIV unit
with peripheral is shown below.
•A DC power supply is connected to MIV unit to supply 300 VDC and 24 VDC (control power).
•MIV unit communicates with peripherals through the servo link, the encoder link, and the con-
verter link.
•MIV unit has a built-in control board specially used for motor control to control a spindle motor
and an axis drive motor.
•Two types of MIV unit are provided; one-axis specification which controls one motor and two-
axis specification which controls two motors.
•A DC power supply unit can be connected to more than one MIV unit.

3. Cautions on Changing Units
3-1. General Precautions
Eeospcsa1010
The items that require special attention when changing MIV unit are indicated below.
WARNING
(1) It is necessary to set a controller ID number after changing MIV unit. Set the controller ID num-
ber referring to 5 "Controller ID Number" in this manual or the circuit diagram after changing the
MIV unit.
(2) Unit type of MIV units differs according to the unit capacity, the control board and the software
(ROM). When changing a unit, make sure to use the unit of the same type.
EIOSPCSA1008R01
WARNING
MIV unit has a large-capacitance capacitor in the unit. When changing MIV unit, shut off the
power and wait until the charge indicating lamp goes off. (Wait for at least 2 minutes after shutting
off the power.)
High voltage is applied to the upper and lower terminal blocks in the unit.
Do not remove the plastic terminal block cover while the power is on.

(3) The procedure for removing the plastic cover at the upper and lower terminal blocks is indicated
below.
•Plastic cover at the upper terminal block
After pushing in the lock lightly, tilt the cover 10 deg. to the front and the cover can be taken
out upward.
•Plastic cover at the lower terminal block
After pushing in the lock lightly, turn the cover 90 deg. then pull the cover to the front and the
cover can be removed.
