Securely fix the servomotor to the machine. Insufficient fixing could lead to the servomotor slipping off during operation.

Always install the servomotor with reduction gear in the designated direction. Failure to do so could lead to oil leaks.

Never touch the rotary sections of the servomotor during operations. Install a cover, etc., on the shaft.

When installing a coupling to a servomotor shaft end, do not apply an impact by hammering, etc. The detector could be damaged.

Do not apply a load exceeding the tolerable load onto the servomotor shaft. The shaft could break.

When storing for a long time, please contact the Service Center or Service Station.

v

CAUTION

(2) Wiring

Correctly and securely perform the wiring. Failure to do so could lead to runaway of the servomotor.

Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the servo drive unit.

Correctly connect the output side (terminals U, V, W). Failure to do so could lead to abnormal operation of the servomotor.

Do not directly connect a commercial power supply to the servomotor. Doing so could lead to faults.

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 malfunction so that signals are not output, and emergency stop and other safety circuits are inoperable.

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 power supply line 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 operation could become unstable.

vi

CAUTION

(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 servomotor or servo drive unit.

Unqualified persons must not disassemble or repair the unit.

Never make modifications.

Reduce magnetic damage by installing a noise filter, etc. The electronic devices used near the servo drive unit could be affected by magnetic noise.

Use the servomotor, servo drive unit 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.

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.).

In the following explanations on bits, set all bits not used, including blank bits, to "0".

When the breaker is shared for multiple power supply units, if a short-circuit fault occurs in the unit with the smallest capacity, the breaker may not function. This is dangerous, so do not share the breaker.

Please do not use a dynamic brake as a usual slowdown stop. When continuation operation is carried out, the brake resistance for dynamic may be damaged.

(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.

MDS-C1 Series servo and spindle system outline

The MDS-C1 Series is MELDAS drive system that has been developed totally connected the servo drive and spindle drive sections.

The MDS-C1 Series is the successor to the MDS-B Series, and has been developed to satisfy European Safety Standards. This Series has the following features.

(1)Compact and lightweight

The converters that were conventionally built in each servo and spindle drive have been integrated into one unit. The drive system volume, installation area and weight have been drastically reduced with the incorporation of high density mounted electronic parts IGBT-IPM (Intelligent Power Module) and the high performance heat radiating fin.

(2)Standardization of dimensions

The outline has been standardized to the book end type, and by unifying the height and depth dimensions, installation in control box has been made easy. Furthermore, by matching the shape with the NC unit (M500 Series), an integrated appearance with the NC has been realized.

(3)Low heat generation

By incorporating the IPM and using power supply regeneration in the servo drive, the amount of heat generated has been greatly reduced.

(4)High speed and precision processing

A high speed CPU has been mounted on the control PCB, and a 100,000 pulse/rotation sub micron detector has been incorporated as a standard to allow faster and more precise interpolation.

By incorporating the stable position loop control (SHG control) method, having an outstanding response, the positioning time and tracking have been improved and the machine vibration during acceleration/deceleration has been reduced.

The cutting performance and cutting precision during position control have been improved by using the high speed CPU also for the spindle drive.

(5)High speed spindle orientation

Smooth operations and minimum orientation times have been realized by using the high speed orientation method while allows direct orientation from the high speed during the spindle drive.

(6)Features of the MDS-C1 Series

(a)European Safety Standards compliant

This Series complies with the European Safety Standards (LVD Directives). (Refer to the section "Compliance to European EC Directives" for details.)

(Note that the C1 Series target units are limited to the CV (power regeneration power supply), SP (spindle drive) and V1/V2 (1, 2-axis servo drive).)

(b)Addition of power supply emergency stop input line

With the C1 Series, the external contactor can be directly shut off from the power supply even when the emergency stop hot line from the NC does not function for any reason.

(This function is validated with the rotary switch and connected drive parameter settings. Thus, the functions do not change from the conventional functions when used in the same manner as the A Series.)
