unexpected operation.

The parameter settings must not be changed excessively. Operation will be insatiable.

(4) Usage CAUTION

Provide an external emergency stop circuit to ensure that operation can be stopped and power switched

off immediately.

Any person who is involved in disassembly and repair should be fully competent to do the work.

Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an

accident. A sudden restart is made if an alarm is reset with the run signal on.

Do not modify the equipment.

Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by

electronic equipment used near the servo amplifier.

Use the servo amplifier with the specified servo motor.

The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used

for ordinary braking.

For such reasons as service life and mechanical structure (e.g. where a ballscrew and the servo motor

are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety,

install a stopper on the machine side.

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 marking). 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 directive

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 organization, to comply with the low voltage directive.

(3) Machine directive

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

2. PRECAUTIONS FOR COMPLIANCE
