1.2Safety precautions
Observe the safety precautions in the PWM 20 Operating Instructions (ID 1125089-90).
Note
Observe the safety precautions below to avoid injury or damage to persons or products.
To avert potential dangers, only use the product in the manner described!
Before you integrate the test units into the position control loop of an NC controlled machine tool make sure that
1.the machine is switched off!
2.all connectors are disengaged! Observe the ESD precautions!
Make sure that the connector contacts are clean!
3.Reestablish all required connections and secure them mechanically. Make the required settings on the PWM.
Switch the machine and the control back on again.
Attention |
Check whether the machine axis can be traversed in a controlled manner.
During the start-up phase of the machine, the emergency stop button must be accessible in time.
DANGER
Do not operate defective units!
No persons are permitted in the traverse range of the machine.
Do not change any parameters or encoder voltages at the test units while the machine tool is moving and a test unit is connected to the position control loop!
Changed parameters must be reset to their original values.
Ensure that vertical axes cannot fall down!
The ATS software offers the possibility of storing and editing machine-specific or equipment-specific information in the customer’s memory area. The data may comprise safety-relevant information.
When servicing, please take care to adjust this memory area. Noncompliance with this warning could result in damage to the machine or in personal injury.
When troubleshooting always contact the machine tool builder for information (e.g. meaning of the data in the OEM memory).

HEIDENHAIN ATS Software User's Manual |
3 Commissioning
3.1System requirements
IBM PC or 100 % compatible PC
Dual-core processor with a clock frequency > 2 GHz
RAM > 2 GB
Windows XP, Vista, Windows 7 and 8 (32 / 64 bits) operating system
Free space on hard disk > 200 MB
Note
If these requirements are not met, this may lead to very slow data processing or even to error messages of the ATS software, indicating that certain functions cannot be performed. A computer with USB interface 2.0 and ATS software is required to run the PWM 20. System requirements for PWM 20 and IK 215: see respective operating instructions.
3.2Description of the hardware
The phase-angle measuring unit PWM 20 or the PCI interface card IK 215 are required to run the ATS software.
The PWM 20 replaces the IK 215 entirely. PWM 20 + ATS V2.4 feature all functions of the IK 215. Improvements of the ATS software functions are focused on the PWM 20. Certain functions - such as inspection of incremental and DRIVE CLiQ interfaces, feed-through mode and various mounting wizards - are only supported by the PWM 20.
Note

4 Identifying encoder output signals (encoder interfaces)
4.1Incremental interfaces
Determine interface from encoder designation
Note
The identification of the interface type applies to standard HEIDENHAIN encoders.
Deviations from the designation structure are possible (in particular with customer-specific encoders).
Other identifiers
A 9-pin M23 connector always means an 11 µApp interface.
Encoders connected to the encoder inputs of EXE interpolation electronics are always 11 µApp encoders.
Encoders connected to the encoder inputs of IBV interpolation electronics are always 1 Vpp encoders.
Note
For encoders with D-sub connectors no conclusions can be made about the interfaces.

4.2Absolute interfaces
Encoders that have a 'C' or a 'Q' in their names use an absolute interface (EnDat or SSI).
There are EnDat encoders with and without incremental A/B sinusoidal signals.
The order designation indicates whether an encoder outputs incremental signals:
EnDat 21 |
without incremental signals |
EnDat 22 |
without incremental signals |
EnDat 01 |
with incremental signals A/B 1 Vpp |
EnDat 02 |
with incremental signals A/B 1 Vpp |
EnDat Hx |
with incremental signals HTL (as of 2014) |
EnDat Tx |
with incremental signals TTL (as of 2014) |
x designates: a = 2-fold interpolation b = without interpolation c = scanning signals x2

5.2Setting up a connection to the encoder
Connect the encoder to the test unit with an adapter cable.
Note |
Adapter cables: See User's Manual "PWM 20 Cable and Connection Technology".
This User's Manual can be downloaded from the HEIDENHAIN website, see:
www.heidenhain.de/Documentation and Information/Software/Download Area/Diagnostic
Set/PWM/Documentation.
Double-click "Connect encoder" in the ATS main menu.
The "Encoder selection" window offers two possibilities of powering the encoder and setting the encoder interface:
1Automatic encoder identification by entering the ID of the encoder (mandatory for absolute encoders)
2The manual settings are only used, if no encoder ID is available (ID plate missing or illegible; encoder not in the ATS encoder database).
28 |
HEIDENHAIN ATS Software User's Manual |
3Select "Use power supply from subsequent electronics", if the PWM 20 is in feed-through mode and supposed to be powered from the subsequent electronics.
Exception: Do not set the checkmark for the feed-trough mode with SA 100 / SA 110! The subsequent electronics cannot supply power due to the potential segregation of the SA 100 / SA 110.
The PWM is powered by the subsequent electronics. (PWM 20 in feed-through mode)
Note
"Use power supply from subsequent electronics" is only required for the feed-through mode of the PWM 20. This means that the checkmark may only be set, if the PWM 20 is connected to the control loop between the control and the encoder (closed loop; X2 OUT connected to subsequent electronics) without an SA 100 / SA 110.
Note
HEIDENHAIN recommends automatic connection by entering the ID number. Automatic connection through entering the encoder ID is mandatory for feed-through mode at axes with absolute encoders!
The relevant encoder data is read from a database. This database is part of the ATS software.
The encoder database contains all ID numbers and variants of the encoders that existed when the ATS software was released.
The database is updated about every six months.
You will find the most recent data at www.heidenhain.de.
DANGER
If the manual setting of the encoder parameters does not match the connected encoder, the encoder, the IK 215, the PWM 20 or the computer may be damaged.
Note
For the encoder data, please refer to the respective mounting instructions or machine documentation. Contact the machine manufacturer or the HEIDENHAIN Service.
Encoder connection
Please ensure that the correct supply voltage is selected to avoid damage to the encoder. The cable between the encoder and the PWM 20 must not be connected or disconnected while under power. Otherwise the encoder and the PWM 20 might be damaged.
Check whether the cable between the encoder and the PWM 20 is correctly wired.
The pin layout of the encoder is included in the specifications. The pin layouts of the connecting cables are described in the catalog. An incorrectly wired connecting cable might damage the encoder and the PWM 20.

5.2.1 Feed-through mode
"´Feed-through" mode means connecting the PWM 20 into the control loop of an NC-controlled machine.
For diagnosing, the PWM 20 can be integrated into the control loop of an NC controlled machine tool via adapter cables at the encoder input X1 and the encoder output X2.
For the feed-through mode the power supply must be switched to the subsequent electronics in the ATS software.
Set the checkmark in feed-through mode only.
If no subsequent electronics is connected, the encoder is not powered (error message).
The feed-through mode is supported as of the software version 2.6. We recommend always using the most recent software version (see www.heidenhain.de).
The feed-through mode cannot be used for all interfaces supported by the ATS.
In principle, the following interfaces allow for feed-through mode:
EnDat, Fanuc, Mitsubishi, 1 Vpp, TTL, 11 µApp
EnDat/Fanuc/Mitsubishi
Metallic isolation is possible with the service adapters SA 100 and SA 110.
No metallic isolation, if the measurement is conducted with the PWM 20 only.
For encoders that also support incremental signals, the incremental signals can now also be displayed and evaluated.
EnDat 2.1
Normally, the only communication over the EnDat interface takes place during the start-up stage of the NC (interrogation and transfer of the absolute position data):
"Listening in" on the EnDat communication is not possible. (The synchronization time is too short for the PWM 20.)
The 1 Vpp signals A and B can be displayed.
Note
SIEMENS NC controls currently use EnDat 2.1 with A/B signals and do not support the monitor function!
30 |
HEIDENHAIN ATS Software User's Manual |
EnDat 2.2
Communication takes place continuously. However, there is no prescribed communication pattern. Instead, every OEM determines the sequence of EnDat communication on his own.
No universal “listening in” on the communication is possible.
The monitor function is only possible, if the valuation numbers for online diagnosis are included in data transfer. (The following controls support the monitor function: TNC 620, TNC 640, iTNC 530 [as of NC-SW 34049x-04], iTNC 530 HSCI with diagnostic function and DRIVE-DIAG.)
Synchronization with communication may take some time.
1 Vpp
No metallic isolation, if the measurement is conducted with the PWM 20 only.
Metallic isolation is possible with the SA 100.
The PWM 20 picks off the signals; without 120-ohm signal termination.
The limit frequency is influenced by the test setup (adapter cable, etc.)
11 µApp
The line is interrupted in feed-through mode, i.e. the PWM 20 has an 11 µApp receiver and reproduces the (emulated) input signals at the 11 µApp output.
The limit frequency is influenced by the test setup (adapter cable, etc.)
Not yet approved for ATS V2.8. Signal errors may occur!
TTL
Without PWT switchover:
The PWM 20 picks off the RS-485 signals, i.e. a standard RS-485 receiver without 120-ohm termination is connected to the lines.
Note
Automatic connection through entering the encoder ID is mandatory for feed-through mode at axes with absolute encoders!
Incremental interfaces also permit manual connection by selecting the interface in feed-through mode.
If the feed-through mode is not used, absolute and incremental encoders can be connected manually.
However, automatic connection via the ID number is recommended!
DANGER
Testing cables for feed-through mode are not suitable for regular machine operation. Due to the great variety of machine designs and their grounding variants it is not possible to exhaustively test all testing cables.
It is absolutely necessary that you check the safe and proper function of the testing cables for every test situation!
Uncontrolled axis movements cannot be ruled out when working with testing devices and cables in feed-through mode.
Example for machine axes with absolute encoders:
Determine the encoder ID with the PWM 20 before feed-through operation (no axis movement required).
Automatic connection through entering the encoder ID is mandatory for feed-through mode at axes with absolute encoders. However, the ID is not known and the encoders are not visible under their covers.
The ATS software can read out and display the encoder ID.
