5 Pin Layouts
5.1 Pin Layout of PWM 20
5.2 Pin Layout of the IK 215
X1
The pin layout of PWM 20 is described in the PWM 20 instructions for installation/
commissioning, ID 729905-xx (see PWM 20 basic kit).
Connection of encoder X1
The encoder is connected to the encoder input X1. The layout of the 15-pin D-sub connector
is as follows:
Spannungsversorgung

0 V Sensor Innen-
0 V schirm

Shield on housing; Up = power supply

Attention
A+ A– B+ B– R+ R– DATA DATA CLOCK CLOCK
The power supply of the encoder (pin 4) can be selected by software. Care must be taken
that the correct supply voltage is set at the encoder, since otherwise the encoder, the IK or
the computer may be damaged! Connect or disconnect the encoders only while the power
supply is switched off!
For external functions, a 4-pin female connection is available through which the recording of
measured values can be externally controlled. The required connector can be ordered from
HEIDENHAIN under the ID 282 168-01. The signals are arranged as follows (view of the
connection from outside):
Pin Pin layout
1 Input: Latch pulse (HEIDENHAIN internal use)
2 Output: Sychnronization pulse (HEIDENHAIN internal use)
3 Output: MSB of position value (singleturn), serves as mounting aid for EnDat
motor encoders.
4 GND
