FLU Starter Addendum Elmo Motion Control
FLU - STARTER
Addendum to the FLU Operating Manual
Revision 8/99
Introduction
This addendum is intended for the use of the design engineer who uses a FLU amplifier with a FLU-STARTER evaluation and interface board. This document should be regarded as an extension to the “FLU Operating Manual”, describing ONLY the pins and functions (of the FLU amplifier) that are either different or slightly modified from the description in the “FLU Operating Manual”. The chapters in this document are sequenced in correlation to the chapters in the “FLU Operating Manual” that cover the same information.

Description
Refer to section 2 in the “FLU Operating Manual” The FLU-STARTER is an add-on interconnection board for the FLU servo amplifier that plugs on top of the amplifier. The purpose of this board is the translation of the FLU 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 FLU is kept.
Standard Features
Refer to section 2.1 in the “FLU Operating Manual”
q Four LEDs allow convenient diagnostics of the FLU 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

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 through R4)
Refer to section 3.1 in the “FLU Operating Manual” The user can change the default scale of the differential input (±3.75V) by calculating and inserting R1 through R4 into the designated solderless terminals. The value of these resistors is given by:
R1=R2=R3=R4=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 “FLU Operating Manual” A solderless terminal is available for Reclc. It is designated as R5.
External Current Limit – Peak (ECLP)
Refer to section 3.5 in the “FLU Operating Manual” A solderless terminal is available for Reclp. It is designated as R6.

DIP – Switches
Switch Function ON OFF
S1 CGC CGC – ON (see section 3.3 in “FLU
Operating Manual)
S2 CFM CFM – ON (see section 3.2 in “FLU
Operating Manual)
S3 LM LM – ON (see section 3.6 in “FLU
Operating Manual)
S4 EN+ Setting S4 to ON applies +VCC voltage to
EN+ pin (If +VCC is applied to J4). Setting both S4 & S5 will enable the amplifier without an external signal.
S5
EN
Setting S5 to ON connects VCCRET to EN­pin.
S6 N/C
Supply Voltage (+VCC & VCCRET)
In order to operate the diagnostics LEDs and/or use the enable (EN) feature, an external voltage must be applied to +VCC & VCCRET terminals at J4. The DC supply requirements are as follows:
Min. input voltage 5VDC Max. input voltage 15VDC Max. input current 13 mA
CGC - OFF
CFM - OFF
LM – OFF
No voltage is applied to EN+
No voltage is applied to EN
LED Indications
Refer to section 5 in the “FLU Operating Manual”
