SStart–up/commissioning is prohibited until it has been ensured that the
machine, in which the components described here are to be installed, fufills
the regulations/specifications of the Directive 98/37/EC.
SOnly appropriately qualified personnel may commission/start–up this equip-
ment.
SThis personnel must observe the technical customer documentation rele-
vant to the product and the observe the danger and warning information.
SOperational electrical equipment has parts and components which are at
hazardous voltage levels.
SHazardous axis motion can occur when working with the equipment.
SAll work should be undertaken with the system in a no–voltage condition
!Warning
SPerfect, safe and reliable operation of this equipment assumes that it has
been professionally transported, stored, mounted and installed as well as
careful operator control and service.
SThe information given in catalogs and quotations applies additionally for
special versions of machines and equipment.
SIn addition to the danger and warning information in the technical customer

count.
!Caution
SFor synchronous motors, voltage is present at the motor terminals when the
rotor is turning (integrated permanent magents).
SSurface temperatures of over +100dC can occur on the motors. For this
reason, no heat–sensitive objects, such as cables or electronic compo-
nents, may be attached to or come into contact with the motor surface.

!Caution
Electrostatic dischargesensitive devices are individual components, integrated
circuits, or boards which when handled, tested or transported, could be des-
troyed by electrostatic fields or electrostatic discharge. These components are
designated as ESDS (ElectroStatic Discharge Sensitive Devices).
Handling ESDS boards:
SThe human body, working area and packing should be well grounded when
handling ESDS components!
SElectronic boards may only be touch by personnel in ESDS areas with con-
ductive floor surface if
–they are grounded with an ESDS bracelet
–they are wearing ESDS shoes or ESDS shoe grounding strips.
SBoards should only be touched when absolutely necessary.
SElectronic modules and boards may neither come into contact with plastic
materials nor man–made fibers
SBoards may only be placed on conductive surfaces (desk with ESDS sur-
face, conductive ESDS foam rubber, ESDS packing bag, ESDS transport
containers).
SBoards may not be brought close to data terminals, monitors or television
sets.
A minimum of 10 cm should be kept between the board and the screen.
SMeasurements may be taken on the boards only if
–the measuring equipment is grounded (e.g. via the protective conductor)
or
–in the case of floating measuring instruments, the probe is briefly
discharged before a measurement is taken (e.g. through contact with
bare control housing).

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.
See Catalog NC-Z and NC 60 for ordering information.
