Interface Signal Descriptions

Chapter 7

7-54

Analog Outputs – Two analog outputs with 12 bit D/A resolution can be

programmed to provide any of the following output signals.

• Motor rpm (zero to maximum rpm or – maximum to + maximum rpm)

• Spindle rpm (zero to maximum rpm or – maximum to + maximum rpm)

• % Load

• % Torque

• % Power Output

• Orient Error (full scale is 2 degrees error)

Serial Port – Used for parameter data file upload and download. The port

can be configured (jumper selectable) for RS-232 or RS-422 at 9600 baud.

Conventions Used in this Manual To help differentiate input/output names, programmable parameters and

programmable values, the following conventions will be used throughout

this chapter and the remainder of this manual.

Input and Output Names will appear in Initial Capital Letters

Programming Display Text will appear in italics

Menu Names will appear with ALL CAPITALS

Parameter Names will appear with Initial Capital Letters

Programmable Parameter Values will appear in “quotes”

Signal Level Descriptions The signal level requirements for the various inputs and outputs of the

8510 are as follows:

Digital Inputs

An open or grounded input will result in an Off condition. Inputs must be

pulled high by the external signal to obtain an On condition. An On

condition requires an input between 18 and 30V DC at no more than 10

mA. The reference or ground side of the user supplied source voltage

should only be connected to the drive through the Digital Ground terminals

on the CN9 and CN10 I/O connectors. All inputs are filtered and

electrically isolated to withstand voltage impulses in accordance with

UL-508. Digital inputs are read at 102.4 ms intervals.

Digital Outputs

The digital outputs use dry contact relays rated 200 mA at 24V DC. The

relays provide isolation for the control electronics against voltage impulses

in accordance with UL-508. Unless otherwise noted, when the output is

On, the relay will be energized and the contact closed.
