30.6 PWM 20 encoder diagnostic kit
îš„ Like the IK 215, the PWM 20 phase angle measuring unit is a hardware platform for the
HEIDENHAIN ATS software (adjusting and testing software).
îš„ The above kit currently has the ID 759251-01.
îš„ The PWM 20 can directly be connected to a PC or laptop via the USB interface.
îš„ It serves to inspect and test HEIDENHAIN absolute encoders with EnDat or SSI interface.
îš„ The incremental signals of linear and angle encoders are also displayed.
îš„ With the SA 100 service adapter, the PWM 20 can be connected in series between encoder and
control. Inspections at "operating speed" are possible.
îš„ Parameters (e.g. datum shift), the electronic ID label and OEM information can be read and written
via the EnDat interface.
The PWM 20 encoder diagnostic kit is delivered with detailed operating instructions.
These instructions are also available on the Internet in German and English. They can be
downloaded from www.heidenhain.de/...
A detailed explanation of the PWM 20 encoder diagnostic kit is part of our training courses
on measuring systems.
We recommend that you participate in a HEIDENHAIN service training course so that you can use
the PWM 20 correctly and efficiently.
Contact HEIDENHAIN Traunreut or your regional agency.
