Encoder outputs
The IK 220 also feeds the encoder signals from inputs X1 and
X2 as sinusoidal current signals (11 µA
PP
) to two 10-pin
MICROMATCH connectors (female) on the PCB. An additional
cable assembly with PC slot cover (Id. Nr. 340 252-01) can be
used to lead these connections out to 9-pin D-sub connectors.
Adapter cables (Id. Nr. 309 781-xx) for connecting HEIDENHAIN
position displays and interpolation units are available (see
“Items supplied” and “Accessories”).
The maximum cable length depends on the input circuit of the
subsequent electronics.
