7.2 Connecting the encoders
7.2.1 General information
Encoders report positions and movements of the machine to the iTNC 530
HSCI. HEIDENHAIN contouring controls operate with incremental encoders
with a 1 V
PP
signal and absolute encoders with EnDat interface.
Please use only HEIDENHAIN encoder cables, connectors and couplings.
On the CC 61xx there is a fixed assignment between the input of the speed
encoder, the PWM output and the input of the position encoder.
7.2.2 Position encoders
Incremental position encoders with 1 V
PP
signals and absolute encoders with
EnDat interface can be connected to the CC 61xx. In MP118.x, the position
encoder input for the axes is configured for specific axes. In MP119.x, the
position encoder input for the spindles is configured for specific axes.
 Set the encoder signal with MP118.x and MP 119.x bit 0.
 Set the maximum input frequency with MP118.x and MP 119.x bit 2.
 Set the encoder type (analog or digital) with MP118.x and MP 119.x bit 3.
