SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
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 interconnection 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 polarity is incorrect.
(3) Connect inputs and outputs of a unit correctly. If they are connected incorrectly, failure or burning 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.

SECTION 1 INVERTER UNIT (MIV UNIT)
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
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
converter 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
The items that require special attention when changing MIV unit are indicated below.
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.)
(1) It is necessary to set a controller ID number after changing MIV unit. Set the controller ID
number referring to 5 “Controller ID Number” in this manual or the circuit diagram after changing
the MIV unit.
4184-E P-15

4184-E P-16
SECTION 1 INVERTER UNIT (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.
SE34006R0700300120001
WARNING
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.

3-2. Specific Examples of Unit Replacement
Replacement of some unit models may also involve changing wiring. Specific examples of replacing
such units are shown below.
3-2-1. Example of replacing an MIV unit with another MIV unit
(1) Replacing the MIV06-1, MIV08-1 or DBR8
If any of the 1006-2218 (MIV06-1), 1006-2219 (MIV08-1) or 1006-2246 (DBR8) is faulty, replace
the unit according to the instructions shown in the table below.
Old unit name New unit name Replacement procedure
MIV06-1+DBR8 → MIV06DB-1 Remove the DBR8 (see Fig. 1).
MIV08-1+DBR8 → MIV08DB-1 Remove the DBR8 (see Fig. 1).
MIV06-1 *1 → MIV06DB-1 Follow the regular unit replacement procedure.
MIV08-1 *1 → MIV08DB-1 Follow the regular unit replacement procedure.
*1: The MIV06-1 and the MIV08-1 for PREX motors are not equipped with a DBR8.
CAUTION
4184-E P-17
Do not replace the MIV06DB-1 and the MIV08DB-1 with the units shown below.
Malfunction will result.
MIV06DB-1 → MIV06-1, MIV08DB-1 → MIV08-1
(2) Replacing the MIV14-3
Replace the MIV14-3 with the MIV15-3. This replacement work does not need the installation of
software, such as servo data.

MIV14-3 → MIV15-3
(3) Replacing the MIV30-3
Replace the MIV30-3 with an MIV30-3 or MIV45-3. Replacement with an MIV45-3 does not
need the installation of software, such as servo data.

Faulty!
After replacement
MIV06DB-1 only
What must be removed and colleted in addition to the faulty MID-06-1:
(1) DBR8 unit
(2) Cable between the DBR8 terminal block and the MIV06-1 terminal block
(3) Cable between the DBR8 connector [DBR] and the MIV06-1 connector [BRB]
(4) Cable between the DBR8 connector [DC] and the terminal block of the control box
Note) Do not fail to connect the appropriate cable to this connector.

3-2-2. Replacing an MIV unit with an MIV-A unit
(1) Changing unit setscrew
The plate thickness may differ between MIV unit and MIV-A unit at the sect6ion fixed to the
control panel. In this case, other setscrews are necessary. Refer to the Table 3-1 and prepare
necessary setscrews.

(2) Replacing the unit with the one having an attachment plate
When MIV unit was switched to MIV-A unit, the unit width was cut short for some units. To
provide compatibility, attachment steel plate is added. For the units listed in the table below, the
width was changed. When these units are replaced, refer to Fig. 3-1.
