Heidenhain PWM21 with ATS software, New software version v4.0.0– September 2025

Company News – September 2025

HEIDENHAIN offers an adjusting and testing package for the diagnosis and adjustment of HEIDENHAIN encoders with absolute and incremental interfaces. It consists of the following components:
PWM 21: inspection device with USB connectability to a PC
ATS Software: adjusting and testing software with integrated local encoder database for automatic encoder identification
The ATS software version that has been available up to now (V3.8.02) is now being succeeded by ATS V4.0.0.

E-Motion America Inc. reminds our customers that ATS V4.0.0 can now be downloaded from the Software Filebase:

Inspection and testing devices from HEIDENHAIN

HEIDENHAIN encoders provide all the information needed for initial setup, monitoring and diagnostics. For the analysis of these encoders, HEIDENHAIN offers the appropriate PWT testing units Encoders LIC 21xx, LIC 31xx, LIF 4xx, LIF 1xx, LIDA 4xx, LIDA 2xx, and ERM 2xxx LIC 41xx, LIP 3xx, LB 3xx, LC 2xx, PP 281, ECA 4xxx, ECM 24xx, ERA 4xxx, ERA 7xxx, ERA 8xxx, and ERP 880 LIP 2xx, LIP 6xxx, ERP 1xxx, ERO 2xxx, PP 6xxx, and MKV 1xxx Range of functions and PWM inspection devices. The PWM inspection devices, which are universally deployable, feature narrow measuring tolerances and can be calibrated. Testing devices such as the PWT 101 provide fewer functions, have wider tolerances and cannot be calibrated.

Mounting wizard
For mounting exposed or multi-section linear encoders, or modular angle encoders, Heidenhain recommends using the PWM 21 with the ATS software. If supported by the encoder interface, the PWT 101 can be used as well, but with limitations. Please note the information in the encoder documentation regarding mounting and the availability of a mounting wizard.


Overview of important new functions with ATS software V4.0:

• Optimized user guidance in the connection dialog • Support of EnDat 3 features:
– Support of encoders with vibration analysis (for example, display of order analysis and loading of configuration f iles)
– Display of associated memory areas • Tape-tensioning wizard optimized for scale tapes without a defined absolute starting value • Modifications in the verification wizard: Functional safety for linear encoders with DRIVE-CLiQ interface • Extended mounting wizard for new encoders

Range of functionsThe ATS software guides the user through the encoder inspection process. After the encoder is connected, various functions are available depending on the encoder interface or the operating mode. A mounting wizard provides support for encoder-mounting functions and for testing functional safety. Based on the measurement function, there are various possibilities for recording the results. In certain cases, a signal adapter may be needed as well.For more information, please contact us
