COMPLIANCE WITH EC DIRECTIVES

1. WHAT ARE EC DIRECTIVES?

The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January,

1997) of the EC directives require that products to be sold should meet their fundamental safety requirements and carry the CE marks (CE mar king). CE marking applies to machines and equipment into which servo amplifiers have been installed.

(1) EMC directive

The EMC directive applies not to the servo units alone but to servo-incorporated machines and equipment. This requires the EMC filters to be used with the servo-incorporated machines and equipment to comply with the EMC directive. For specific EMC directive conforming methods, refer to the EMC Installation Guidelines (IB(NA)67310).

(2) Low voltage di re ctiv e

The low voltage directive applies also to servo units alone. Hence, they are designed to comply with the low voltage directive. This servo is certified by TUV, third-party assessment orga nization, to comply with the low voltage directive.

(3) Machine directive

Not being machines, the servo amplifiers need not comply with this directive.

The Mitsubishi MELSERVO-J2-Super series general-purpose AC servo is ba sed on the MELSERVO-J2 series and has further higher performance and higher functions. It is connected with a servo system controller or simila r device via a serial bus (SSCNE T) and the servo amplifier reads position data directly to perform operation. Data from a command unit controls the speed and rotation direction of the servo motor and executes precision positioning. A torque limit is imposed on the servo amplifier by the clamp circuit to protect the power transistor in the main circuit from overcurrent due to sudden acceleration/deceleration or overload. The torque limit value can be changed to any value with an external analog input or the parameter. As this new series has the RS-232C serial communication function, a MR Configurator (servo configuration software)-installed personal computer or the like can be used to perform parameter setting, test operation, status display monitoring, gain adjustment, etc. With real-time auto tuning, you can automatically adjust the servo gains according to the machine. The MELSERVO-J2-Super series servo motor is equipped with an absolute position encoder which has the resolution of 131072 pulses/rev to ensure more accurate control as compared to the MELSERVO-J2 series. Simply adding a battery to the servo amplifier makes up an abso lute position dete ction system. This makes home position return unnecessary at power-on or alarm occurrence by setting a home position once.

Merely setting a home position once makes home position return unnecessary at every power-on. Servo amplifier detects mechanical resonance and sets filter characteristics automatically to suppress mechanical vibration. Suppresses high-frequency resonance which occurs as servo system response is increased. Analyzes the frequency characteristic of the mechanical system by simply connecting a MR Configurator (servo configuration software)-installed personal computer and servo amplifier. Can simulate machine motions on a personal computer screen on the basis of the machine analyzer results. The MR Configurator (servo configuration software) is required. Personal computer changes gains automatically and searches for overshootfree gains in a short time. The MR Configurator (servo configuration software) is required.

Suppresses vibration of Automatically adjusts the gain to optimum value if load applied to the servo

motor shaft varies. Higher in performance than MELSERVO-J2 series servo amplifier. Used when the built-in regenerative brake resistor of the servo amplifier does not have sufficient regenerative capability for the regenerative power generated. Used when the regenerative brake option cannot provide enough regenerative power. Can be used with the MR-J2S-500B to MR-J2S-22KB. Used when the regenerative brake option cannot provide enough regenerative power. Can be used with the MR-J2S-500B to MR-J2S-22KB.

Forced stop (EM1) can be automatically switched on internally to invalidate it. Parameter No.23 Output signal can be forced on/off independently of the servo status.

Use this function for output signal wiring check, etc.

2. INSTALLATION

2.4 Cable stress

(1) The way of clamping the cable must be fully examined so that flexing stress and cable's own weight

stress are not applied to the cable connection.

(2) For use in any application where the servo motor moves, fix the cables (encoder, power supply, brake)

supplied with the servo motor, and flex the optional encoder cable or the power supply and brake wiring cables. Use the optional encoder cable within the flexing life range. Use the power supply and brake wiring cables within the flexing li fe of the cabl es.

(3) Avoid any probability that the cable sheath might be cut by sharp chips, rubbed by a machine corner

or stamped by workers or vehicles.

(4) For installation on a machine where the servo motor will move, the flexing radius should be made as

large as possible. Refer to section 11.4 for the flexing life.

3. SIGNALS AND WIRING

Any person who is involved in wiring should be fully competent to do the work. Before starting wiring, make sure that the voltage is safe in the tester more than 10

minutes after power-off. Otherwise, you may get an electric shock.

WARNING

CAUTION

Ground the servo amplifier and the servo motor securely. Do not attempt to wire the servo amplifier and servo motor until they have been

installed. Otherwise, you may get an electric shock.

The cables should not be damaged, stressed excessively, loaded heavily, or

pinched. Otherwise, you may get an electric shock.

Wire the equipment correctly and securely. Otherwise, the servo motor may

misoperate, resulting in injury.

Connect cables to correct terminals to prevent a burst, fault, etc. Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur. The surge absorbing diode installed to the DC relay designed for control output

should be fitted in the specified direction. Otherwise, the signal is not output due to a fault, disabling the forced stop(EM1) and other protective circuits.

Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF

option) with the power line of the servo motor.

When using the regenerative brake resistor, switch power off with the alarm signal.

Otherwise, a transistor fault or the like may overheat the regenerative brake resistor, causing a fire.

Do not modify the equipment.

CAUTION

When an alarm occurs in the servo amplifier, t he base circuit is shut off and the servo motor is coated to a stop. Switch off the main circuit power supply in the external sequence. To deactivate the alarm, power the control circuit off, then on or give the error reset or CPU reset command from the servo system controller. However, the alarm cannot be deactivated unless its cause is removed.

If operation is repeated by switching control circuit power off, then on to reset the overcurrent (32), overload 1 (50) or overload 2 (51) alarm after its occurrence, without removing its cause, the servo amplifier and servo motor may become faulty due to temperature rise. Securely remove the cause of the alarm and also allow about 30 minutes for cooling before resuming operation.

(2) Regenerative alarm

If operation is repeated by switching control circuit power off, then on to reset the regenerative (30) alarm after its occurrence, the external regenerative brake resistor will generate heat , resulting in an accident.

(3) Instantane ou s pow e r fa il ur e

Undervoltage (10) occurs if power is restored after a 60m s or longer power failure of the con trol circu it power supply or after a drop of the bus voltage to or below 200VDC. If the power failure persists further, the control circuit power switches off. When the power failure is rese t in this state, the alarm is reset and the servo amplifier returns to the initial state.

and charging area exposed and you may get an electric shock.

During power-on or operation, do not open the front cover. You may get an electric

shock.

Before starting operation, check the parameters. Some machines may perform

unexpected operation.

Take safety measures, e.g. provide covers, to prevent accidental contact of hands

and parts (cables, etc.) with the servo amplifier heat sink, regenerative brake resistor, servo motor, etc.since they may be hot while power is on or for some time after power-off. Their temperatures may be high and you may get burnt or a parts may damaged.

During operation, never touch the rotating parts of the servo motor. Doing so can

cause injury.

Connect the servo motor with a machine after confirming that the servo motor operates properly alone.

(1) Power on

When the main and control circuit power supplie s are switched on, "d1" (for the fir st axis) appears on the servo amplifier display. In the absolute position detection system, first power-on results in the absolute position lost (25) alarm and the servo system cannot be switched on. This is not a failure and takes place due to the uncharged capaci t or in the enc o de r. The alarm can be deactivated by keeping power on for a few minutes in the alarm status and then switching power off once and on again. Also in the absolute position detection system, if power is switched on at the servo motor speed of 500r/min or higher, position mismatch may occur due to external force or the like. Power must therefore be switched on when the servo motor is at a stop.

(2) Parameter setting

Set the parameters according to the structure and specifications of the machine. Refer to Chapter 5 for the parameter definitions.

Parameter No. Name Setting Description

7 Rotation direction setting 0 8 Auto tuning 1Used.

9 Servo response 5 Slow response (initial value) is selected.

(4) Home position return

Always perform home position return before starting positioning operation.

(5) Stop

If any of the following situations occurs, the servo amplifier suspends the running of the servo motor and brings it to a stop. When the servo motor is equipped with an electromagnetic brake, refer to Section 3.7.
