If the encoder is equipped with incremental signals, the IK 115
very loosely monitors the signal amplitude (see following
illustration).

Faulty incremental signals may cause serious problems in the
evaluation of the subsequent electronics even below the
response threshold (220 mV

PP

) of the IK 115 signal monitor.

For a precise analysis of the incremental output signals, we
recommend our PWM 8 phase meter, which is available
through your HEIDENHAIN service agency.
