VIO Starter Addendum Elmo Motion Control

Rev. 1/07

Description

Refer to section 2 in the “VIO Operating Manual”

The VIO-STARTER is an add-on interconnection board for the VIO servo amplifier

that plugs on top of the amplifier. The purpose of this board is the translation of the VIO

solder type pins into screw type terminals thus enabling easy connectivity for evaluation

and low quantity applications.

One to one relationship between board terminals and the pins of the VIO is kept.

Standard Features

Refer to section 2.1 in the “VIO Operating Manual”

q Four LEDs allow convenient diagnostics of the VIO status outputs

q The dedicated digital inputs can be activated by DIP switches

q Scaling resistors are provided for adjusting the current limits and the command

reference

Type designation

VIO-Starter

Pins functions

There is a new terminal strip – J4 with the following functions:

Terminal Function

+VCC Positive supply voltage for the LED’s

VCCRET Return for the LED supply voltage

Current Command Scaling Resistors (R1 & R2)

Refer to section 3.1 in the “VIO Operating Manual”

The user can change the default scale of the differential input (±3.75V) by calculating

and inserting R1 & R2 into the designated solderless terminals. The value of theses

resistors is given by:

R1=R2=5.33*Vcref-20 [KΩ]

Vcref is the desired maximum reference voltage.

If for example, the new desired scale is ±10V, all that is required is to change the

default resistors (0 ohms) to 33Kohm.

External Current Limit – Continuous (ECLC)

Refer to section 3.4 in the “VIO Operating Manual”

A solderless terminal is available for Reclc. It is designated as R3.

External Current Limit – Peak (ECLP)

Refer to section 3.5 in the “VIO Operating Manual”

A solderless terminal is available for Reclp. It is designated as R4.
