WARNING!
During commissioning, remove the fuses (or trip the circuit breaker) on your 3-
phase supply.
Make sure the power is OFF, and that it cannot be switched on accidentally whilst you
are working.
REFER TO YOUR MAIN PRODUCT MANUAL FOR SPECIFIC SAFETY
INFORMATION ABOUT THE DEVICE YOU ARE CONTROLLING
IMPORTANT: Please read this information BEFORE installing the equipment.
Intended Users
This manual is to be made available to all persons who are required to install, configure or
service equipment described herein, or any other associated operation.
The information given is intended to highlight safety issues, EMC considerations, and to enable
the user to obtain maximum benefit from the equipment.
Application Area
The equipment described is intended for industrial motor speed control utilising AC induction or
AC synchronous machines.
Personnel
Installation, operation and maintenance of the equipment should be carried out by qualified
personnel. A qualified person is someone who is technically competent and familiar with all
safety information and established safety practices; with the installation process, op eration and
maintenance of this equipment; and with all the hazards involved.
Safety
All control and signal terminals are SELV, i.e. protected by double insulation.
EMC
In a domestic environment this product may cause radio interference in which case the user may
be required to take adequate counter-measures.
This equipment contains electrostatic discharge (ESD) sensitive parts. Observe static control
precautions when handling, installing and servicing this product.
Safety Information

Cont.3
CAUTION!
At any time, there may be a loss of motor control and separate/independent application
measures should be taken to ensure that such loss of motor control cannot present a safety
hazard.
RISK ASSESSMENT
Under fault conditions, power loss or unintended operating conditions, the drive may not
operate as intended. In particular:
• Stored energy might not discharge to safe
levels as quickly as suggested, and can still
be present even though the drive appears to
be switched off
• The motor's direction of rotation might not
be controlled
• The motor speed might not be controlled
• The motor might be energised
A drive is a component within a drive system that may influence its operation or effects under
a fault condition. Consideration must be given to:
• Stored energy • Supply disconnects • Sequencing logic • Unintended
operation

8902/RE Resolver Speed Feedback Option
RESOLVER SPEED FEEDBACK OPTION
Description
The 8902/RE and 8902/RR Resolver Speed Feedback Options allow resolvers to be connected
directly to the motor controller to provide highly accurate speed feedback measurement.
In addition, the 8902/RR provides an emulated
pulse encoder output.
Features
The Option has the following features:
• Contains two differential inputs on channels
Sin and Cos
• Contains a carrier output signal to power the
Resolver
• 8902/RR contains three differential outputs,
emulating a pulse encoder.
