Coupling spring

Fasten the coupling spring by means of

M4x8 screws in the mounting holes provi-

ded on the encoder housing. Slide encoder

onto the drive shaft and fix the coupling

spring on the surface provided.

All movable adjusting elements need tolerance in both

axial and radial direction in order to equalize shifts by tem-

perature and of mechanical nature. Tighten both fixing and

clamp ring screws firmly. The spring coupling is not

allowed to have any contact to the encoder or motor

except on the mounting point

Electrical installation

Do not modify encoder in any electrical way and carry

out any wiring work under power supply.

Any electrical connection and plugging-on whilst under

power supply is not permitted.

A separate encoder supply has to be provided with con-

sumers with high interference emission.

Encoder case and supply cable have to be completely

screened.

Installation of the whole system has to be according

to EMC standards. Installation environment as well as

wiring have an impact on the encoder’s EMC. Encoder

and supplying lines are to be in separated locations or

remote from lines with high interference emission (fre-

quency transformers, protections, etc.).

Ground (PE) encoder by using screened cables. The brai-

ded shield has to be connected to cable gland or plug.

Grounding (PE) on both sides is recommended.Ground

the case by the mechanical assembly, if latter is electri-

cally isolated a second connection has to be provided.

Ground cable screen by the subsequently connected

devices. In case of ground loop problems at least groun-

ding on one side is imperative.

Disposal

Encoder components are to be disposed of according to

the regulations prevailing in the respective country.

Transport and storing

In original packing only.

Do not drop or expose encoder to major shocks.

Assembly

Open clamping ring completely before mounting the

encoder.

Avoid punches or shocks on case and shaft.

Avoid case distortion.

Do not open or modify encoder in any mechanical way.

The spring arm of the spring coupling has to be free

movable.

Shaft, bearing, glass disc or electronic componen-

ts might be damaged and a secure operation is no

longer guaranteed.

Hollow shaft assembly

Mounting with clamping ring

Plug encoder completely onto drive shaft (ISO-fit g7).

Position of the clamping ring has to be set properly to the

hollow shaft slot (see drawing) and tighten clamping ring

firmly.

Starting torque
Spring coupling mounting

M3 max. 1.2 Nm / M4 max. 1.9 Nm
Clamping ring mounting M3 max. 1.2 Nm

Mechanical mounting

Encoder torque pin

Slide encoder onto the drive shaft and insert

torque pin into the adjusting element provi-

ded by customer.

Adjustment

piece

with

rubber spring element

Slide encoder onto drive shaft. Insert

cylinder pin into the mounted adjusting part

(with rubber spring element) provided by

customer.

Angled adjustment

Slide encoder onto the drive shaft. Insert

adjusting angle into the encoder´s rubber

spring element and fix the adjusting angle

at the provided surface.

Shoulder screw

Slide encoder onto the drive shaft and po-

sition the shoulder screw in the encoder´s

rubber spring element.

Any disregard may lead to malfunctions, material damage

and personal injury.

Electrical connection

Any outputs not used must not be connected. Unused

cable cores have to be isolated.

After the reset process the zero input should be groun-

ded (GND) externally for better protection against inter-

ferences.

The encoder must not be programmed during operati-

on.

Maximum bending radius 90 mm.

Mating connector for connecting cable available as

spare part, please see accessories.

In case of using any customer-specific cables apply

only shielded lines and connectors according to EMC

standards. Consider the assembly instructions of the

respective supplier.

Configuration and Parameter Setting

Accessories required:

PC with RS232 interface and Windows operation sy-

stem.

ProCam software and two adaptor cables, refer also to

accessories.

Connect PC to the encoder’s programming interface by

using the programming cable.

Tighten both nut of the connector as well as locking

screws of the SUB-D plug as far as possible.

Connect encoder to power supply by the adaptor cable.

Switch on power supply.

For encoder configuration and parameterizing please refer

to the respective manual.

Assembly Instructions

Danger

Warnings of possible danger.

General instructions

Information on appropriate product handling.

General remarks

Additional information

The installation instruction is supplementary to already

existing documentation (e.g. catalog, data sheet, manual).

It is imperative to read the manual carefully prior to star-

ting the device.

Appropriate use

The encoder is a precision measuring device. It is ex-

plicitly designed for registration of angular positions

and revolutions as well as evaluation and supply of

measuring values as electric output signals for the sub-

sequently connected device. The encoder must not be

used for any other purpose.

Start up

Installation and assembly of the encoder only by electri-

cally skilled and qualified personnel.

Consider also the operation manual of the machine

manufacturer.

Safety instructions

All electrical connections are to be revised prior to star-

ting the system.

Incorrect assembly and electrical connections or any

other inappropriate work at encoder and system may

lead to malfunction or failure of the encoder.

Any risk of personal injury, damage of the system or

company equipment due to failure or malfunction of the

encoder has to be eliminated by corresponding safety

measures.

Do not operate encoder beyond the limit values stated

in the data sheet.

Any disregard may lead to malfunctions, material damage

and personal injury.
