Module Specific Modes
This section explains how the three availabe inputs can be configured. The PD42-1270 implements
three different predefined modes, each one with a different set of functions for these three pins. Axis
Parameter number 254 “Module Specific Mode” (see Section

) contains the current mode. In Table
16
, the
functionalities for all three pins in each configuration are shown.

In Mode Reference, the three digital inputs correspond to reference switches: Home, Left Endstop and
Rigth Endstop for GPI 1, 2 and 3 respectively. The Reference Search feature is only available in this mode.
See more information about Reference Seach in Section
7.1
.
In Mode Encoder, GPI2 and 3 correspond to the encoder pins A and B.
Finally, all three inputs are function free inputs available for the user in Mode GPI.
All these inputs are read with a Get Input TMCL Command with Bank 0 (Digital Inputs). The only exception
is GPI1 in Mode GPI (Analog Input 1), which is read with Bank 1 (analog inputs). See more information
about how to read the state of an input in Section
