Encoder diagnostics
HEIDENHAIN encoders provide all of the information needed for their own setup,monitoring and diagnostics.

PWM 21The PWM 21 inspection device, including the ATS software, is used for diagnosing
and adjusting HEIDENHAIN encoders with absolute and incremental interfaces.

The exact information depends on the interface and the type of encoder. To help
you analyze this data, HEIDENHAIN offers the PWT testing devices and the PWM
inspection devices.
The PWM 21 inspection devices can used with all HEIDENHAIN encoders, feature
low measuring tolerances and can be calibrated. Testing devices such as thePWT 101 offer fewer functions, have wider tolerances and cannot be calibrated.

Diagnostic capabilities• Encoder diagnostics with the PWM and PWT:The encoder is connected directly to the testing or inspection device• Diagnostics within the control loop with the PWM:
The PWM inspection device is interposed within the closed control loop

PWT 101
The PWT 101 is a testing device for the functional testing and adjustment ofabsolute and incremental HEIDENHAIN encoders.

PWM 21 inspection device
HEIDENHAIN offers a package for diagnosing and adjusting HEIDENHAIN
encoders with absolute and incremental interfaces. It consists of the PWM 21and the ATS software. The inspection device is connected to a PC via a USB port.
The ATS adjustment and inspection software features a local encoder databasefor automatic encoder detection.

Functionality
The ATS software supports a variety functions, limited only by the specific encoder
and its interface. If an encoder uses the EnDat interface, then along with displaying
the position value, the package can output the encoder’s online diagnostics, readand write its parameters, shift its datum, set write protection and perform otherinspection functions.

PWT 101 testing device
The PWT 101 is a testing device for the functional testing and adjustment ofabsolute and incremental HEIDENHAIN encoders. Thanks to its compact andrugged design, the PWT 101 is ideal for portable use. A 4.3” touchscreen serves
as both its display and operating screen.

Mounting wizard
The PWM 21 is recommended as a mounting tool for the adjustment of HEIDENHAIN
encoders that require a special mounting wizard (e.g., the LIP 2xx, ERO 2xxx).

Encoder interfaces
The PWT 101 supports a variety of functions, limited only by the specific encoderand interface. If the encoder uses the EnDat interface, then along with displaying
the position value, the PWT 101 can output its online diagnostics, shift its datum
and perform other inspection functions.

For more information, see the PWT 101 Product Information document at:https://www.heidenhain.com/service/downloads/brochures• Testing device with integrated 4.3” touchscreen• Power via external power supply unit
• Expandable functionality through firmware updates

Functionality
The functionality of the PWT 101 can be expanded through a firmware update.
The firmware files are available at www.heidenhain.de. They can be uploaded
to the PWT 101 via a memory card (not included).
