SAFETY PRECAUTIONS

4742-E P-(i)

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 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.

Eeospcspl001

(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.

SECTION 1 INVERTER UNIT (MIV UNIT)

4742-E P-1

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 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.

3-1. General Precautions

4742-E P-11

SECTION 1 INVERTER UNIT (MIV UNIT)

The items that require special attention when changing MIV unit are indicated below.

Eeospcsa1010

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 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.

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.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

EIOSPCSA1008R01

(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.

SECTION 1 INVERTER UNIT (MIV UNIT)

MIV unit shows the operating status at the 7-segment LED provided at the front of the unit. Two display modes (normal operation status display mode and alarm status display mode) are provided and at the occurrence of an alarm, the 7-segment LED displays an error number so that the cause of the alarm can be assumed.
