SIMODRIVE sensor, Measuring System for Main Spindle Drives SIMAG H (PMH) – 07.02 Edition

General Information

SIMAG H is an incremental measuring (encoder) system for sensing angles of

rotation and angular velocity.

The system is designed for hollow-shaft applications with 1FE1 and 1PH2 direct

drives, but is also capable of operating as an autonomous spindle encoder.

SIMAG H can be used with the following SIEMENS drive systems:

SSIMODRIVE 611 digital

SSIMODRIVE 611 analog (in this case, only in conjunction with the measuring

wheel, pole number 2n)

SMASTERDRIVES

The SIMAG H measuring system consists of three components.

SSensor wheel

SSensor head with attached gauge holder plus

1 feeler gauge (0.20 mm) and

1 3x12 cylindrical pin

SFully pre-assembled cable module with

4 M 2.5x8 screws for mounting the flange-mounted socket and

2 M 3x6 screws for attaching the connector to the sensor head

The sensor wheel carries a magnetic pitch as a fixed gauge. Various different

inside diameters are available for each outside diameter. The inside diameter

can be re-machined later if required.

The sensor wheel is attached by means of the shaft nut or, alternatively, scre-

wed to a shaft collar (not suitable for all sensor wheel variants).

The sensor head scans the incremental and reference tracks on the sensor

wheel by a non-tactile method and amplifies the output signals.

The standard signal cables are connected via the flange-mounted socket on the

cable module. This is fully pre-assembled and attachable to the sensor head.

In this way, the measuring system can be optimally adapted to the prevailing

installation conditions.

Installation and mounting drawing 5-2.

Notice

SIMAG H is a measuring instrument.

The encoder system must always be installed by a qualified person.

Any type of damage will impair the function of the instrument or render the

system unserviceable.

Leave the encoder components in their packaging until you are ready to install

them!

Please apply ESDS protection measures (refer to the Foreword).

Disconnect the power supply before commencing with the installation.

No liability will be accepted for any damage caused by improper handling of

components.

After installation and calibration, the measuring system supplies

Stwo sinusoidal incremental signals of 1 Vpp in quadrature

Sone square-wave reference signal per revolution

Note

SIMAG H is compatible with SIMODRIVE motor measuring systems in terms of

electrical signals and signal connector.

The SIMAG H measuring system is scheduled to supersede the SIZAG 2 ge-

arwheel encoder in the medium term and should therefore be considered for

new spindle unit designs.

Pre-assembled signal leads are available for connecting the sensor to

SIMODRIVE converters.

4.2 Mounting/adjusting the sensor head

Important

SIMAG H is a measuring instrument.

The sensor head must be screwed to the grounded metal assembly through a

good electrical connection.

The sensor head is adjusted using the feeler gauge provided.

It is neither permissible nor is it necessary to make an adjustment using the

encoder signals.

The specified degree of protection of the encoder system is only guaranteed

when the encoder connector is screwed into place.

Before and during mounting, all parts and mounting surfaces must be free of

any accumulated dirt.

The tightening torques must be carefully maintained (refer to Fig. 5-2).

Numbers in brackets, refer to the positions in Fig.5-2.

1. Insert the cylindrical pin (4) in the alignment bore of the bearing endshield

(10).

2. Position the sensor head (2) over the cylindrical pin and very carefully

press–in.

3. Insert the feeler gauge (5) into the gauge holder (3) of the sensor head; swi-

vel the sensor head onto the sensor wheel.

4. Insert two screws (6) (M4, minimum length 12 mm) with two washers (7) in

the threaded holes of the bearing end shield and slightly tighten.

5. Gently press the sensor head (2) against the feeler gauge and sensor

wheel, tighten the retaining screws (6). Secure the screws so that they can-

not be released.

6. Remove the feeler gauge (5) from the holder; the feeler gauge must be able

to be easily withdrawn, however with slight suction, but without resistance.

7. Check the seating and state of the O ring seal in the connector (8) of the

cable assembly on the encoder side.

8. Remove the gauge holder (3), insert the connector of the cable assembly (8)

and tighten using the two M3x6 screws (9).

4.3 Mounting the cable assembly

Important

The flange-mounted socket must be screwed to an earthed metal object to

make a conductive connection. Remove any paint/varnish on mounting sur-

face.

To ensure fault-free operation, do not open the pre-assembled cable ends.

Dimensions of the flange–mounted socket and mounting holes, refer to Fig. 5-1.

Observe the general guidelines for correctly routing cables regarding EMC.

Prerequisite: The sensor wheel and sensor head have been mounted.

1. Thread the connector of the cable assembly, on the encoder side, as well as

the connecting cable for the motor temperature sensor through the mounting

hole of the flange–mounted socket.

2. Insert the flange–mounted socket in the mounting hole and retain using the

4 M 2.5 screws provided (tightening torque, refer to Fig. 5-2).

3. Route the signal cable to the mounting location of the sensor head and re-

tain using the 2 M3x6 screws provided (tightening torque, refer to Fig. 5-2).

4. Route the temperature sensor cable to the connecting terminal of the motor

temperature sensor; if required, shorten and connect to the motor tempera-

ture sensor.

The polarity must be carefully observed when connecting the tem-

perature sensor cable! Refer to the Product Documentation of the mo-

tor manufacturer.

The color of the cores and polarity of the cable: Refer to the connection

assignment, flange–mounted socket, Section 3.

The following must be observed when routing signal and temperature encoder

cables:

SRoute the cables so that they are not under tension

SDo not route cables over sharp edges

SKeep cables away from rotating parts and components

SSecurely retain in place

SCarefully observe the permissible bending radii (refer to Section 3).
