PWT 101
Testing device for HEIDENHAIN encoders

The PWT 101 is a device for the functional
testing and adjustment of incremental andabsolute HEIDENHAIN encoders. Thanks
to its compact and rugged design, thePWT 101 is ideal for portable use. Operationand visual display are carried out on a
4.3-inch touchscreen.
The PWT 101 supports a variety offunctions depending on the encoder andthe interface. With encoders featuring theEnDat interface, for example, you candisplay the position value, export onlinediagnostic data, shift datums, and perform
further inspection functions.
Inspection and testing devices
from HEIDENHAIN
HEIDENHAIN encoders provide all theinformation needed for initial setup,monitoring and diagnostics. For the analysisof these encoders, HEIDENHAIN offers theappropriate PWT testing units and PWM
inspection devices. The PWM inspection
devices, which are universally deployable,feature low measuring tolerances and canbe calibrated. Testing devices such as thePWT 101 provide fewer functions, havewider tolerances and cannot be calibrated.
Functionality
The functionality of the PWT 101 can be
expanded through a firmware update.
The firmware files are available atwww.heidenhain.com. They can be
uploaded to the PWT 101 via a memory
card (not included).

Key new features in firmware V4.0.0:• Encoders with the EnDat 3 interface
now supported• Standardized user experience for allinterfaces
Successor product to the PWT 100
The PWT 100 is succeeded by thePWT 101, which incorporates thefunctionality of the PWT 100 but also
supports special firmware modules. ThePWT 100 will still be supported by futurefirmware versions but will not permit theuse of firmware modules. The PWT 101 is
supported by firmware V2.2.1 or later.
Firmware modules
The module management function of thePWT 101 differentiates between firmware(basic functions) and firmware modules.
The firmware modules permit theimplementation of special functions andsupport for other encoder manufacturers.

The PWT 101 permits rapid switching
between modules, thus enabling theuser to react flexibly to different kinds ofdemands. The following firmware modules
are currently available for assistance while
checking the function of encoders andadjusting them:• AMO encoders (for more information,visit www.amo-gmbh.com/en)• NUMERIK JENA encoders (for moreinformation, visit www.numerikjena.de/en)• RENCO rotary encoders with and without
block commutation (for more information,visit www.renco.com)
Mounting wizard
The PWM 21, together with the adjusting
and testing software (ATS), is recommended
for the mounting of exposed or multi-section
linear encoders and modular angle
encoders. If supported by the encoderinterface, the PWT 101 can be used as well,
but with limitations.

1)1)	An SA 1210 adapter is required for connecting encoders wtih the E30-R2 ordering designation.
The Bus operation function is not supported.

Note: The USB connection X5 is currently not supported; in the case of AC adapters, there may be regional limitations with regard
to the required testing standard.
A separate version is available for Japan. Consult your contact person at HEIDENHAIN if required.
