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.
