Introduction

Digital Inputs

- The PositionServo has twelve digital inputs that are utilized by the drive for decision making in the User Program.

Example uses: travel limit switches, proximity sensors, push buttons and hand shaking with other devices.

- Each input can be assigned an individual debounce time via MotionView. From the Parameter Tree, select [IO].

Then select the [Digital Input] folder. The debounce times will be displayed in the Parameter View Window.

Debounce times can be set between 0 and 1000 ms (1ms = 0.001 sec). Debounce times can also be set via

variables in the user program.

- The twelve inputs are separated into three groups: A, B and C. Each group has four inputs and share one

common: Acom, Bcom and Ccom respectfully. The inputs are labeled individually as IN_A1 - IN_A4, IN_B1

- IN_B4 and IN_C1 - IN_C4.

- In addition to monitoring each input individually, the status of all twelve inputs can be represented as one binary

number. Each input corresponds to 1 bit in the INPUTS system variable. Use the following format:

C4 C3 C2 C1 B4 B3 B2 B1 A4 A3 A2 A1

- Some inputs can have additional special functionality such as Travel Limit switch, Enable input, and Registration

input. Conﬁguration of these inputs is done from MotionView or through variables in the user program. Input

special functionality is summarized in the table below and in the following sections. The current status of the

drive’s inputs is available to the programmer through dedicated System Flags or as bits of the System Variable

INPUTS. Table 5 summarizes the special functions for the inputs.
