Safety Information
Read this page carefully before installation and use of the instrument, and follow all instructions in this for safe installation of this product.
INTRODUCTION
The following clauses contain information, cautions and warnings that must be followed to ensure safe operation and to retain the instrument in a safe condition.
This product is intended for incorporation into a machine or end product. The end product must comply with all safety aspects of the relevant requirements of the European Safety of Machinery Directive 89/392/EEC as amended, and with those of the most recent versions of standards EN60204-1 and EN292-2 at least.
Only qualified personnel shall carry out installation, adjustment, maintenance and repair of the instrument.
WARNINGS
Any removal from the structure or removal of parts, except those to which access is permitted, is likely to expose live parts and accessible terminals, which can be dangerous to life. Only a qualified person who is aware of the hazard involved shall perform any adjustment, maintenance or repair, of the opened instrument under voltage.
The instrument shall be disconnected from all voltage sources before it is opened (for service).
Any interruption of the protective earth conductors inside the instrument is likely to make the instrument dangerous.
Components, which are important for the safety of the instrument, may only be renewed by components obtained through the Elmo service organization.
Before switching on, ensure that the instrument has been installed in accordance with the Installation Instructions.
Maximum AC & DC supplies must be according to the types described in the operating manual.

Introduction
This manual is intended for the use of the design engineer who is implementing the VIO-Velocity servo amplifier into a machine. It covers the various aspects of the implementation process from basic understanding of the product concept and features, through a detailed explanation of the user accessible functions, down to mounting guidelines and requirements from peripheral devices.
Chapter 2, “Servo Amplifier Description”, includes a description of the various features of the VIO-
Velocity, a list of all the pins and their functions and a block diagram of the product.
Chapter 3, “Operation of the Servo Control”, describes all the user accessible functions and gives
the design engineer the guideline as for how to design the peripheral circuits.
Chapter 4, “Mounting and Wiring Instructions”, covers the requirements from peripheral equipment
like motors, cables, and the power supply in order to achieve successful operation of the VIO-Velocity.
Chapter 5, “Status Indications” summarizes all the indication outputs that are available to the user
in order to determine the amplifier status.

Servo Amplifier Description
The VIO-Velocity extends the VIO line by adding a velocity loop daughter board. This series of miniature servo amplifiers for DC brush motors incorporate custom mixed analog/digital ICs and hybridized power stage. The product meets UL508c and the suitable CE regulations. The power stage is implemented on a single ceramic substrate. This design enables very high thermal conductivity, high current carrying capacity, better EMC and good mechanical strength. The control section is implemented by dedicated custom ICs that contribute to higher and improved performance.
2.1 Standard Features
Operation in current mode or velocity mode Armature feedback with I*R compensation, Tachometer feedback Internal DC to DC converter allows for operation from a single supply Zero dead band Excellent linearity Motor current monitor Current gain change for low inductance motors Current feedback multiplier for low current motors External continuous and peak current limits adjustments Latch mode for the protective features Forward and Reverse limit switches Socketed components for adjusting:
• Continuous current limit
• Peak current limit
• Command scaling
• Tachometer scaling
• Velocity loop tuning
Full array of diagnostic LED’s Additional capacitance on the DC bus DIP switches for selecting functions such as CGC, CFM, Latch mode, Directional limits, and
Enable
An encoder feedback option card can be installed on the basic velocity board when required.
2.2 Fault Protection
• Short between the outputs or between each output and the Power Return.
• Over temperature
• Under/over voltage
