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

Safety Information
DANGER! - Ignoring the following may result in injury
1. This equipment can endanger life by
exposure to rotating machinery and high
voltages.
2. The equipment must be permanently
earthed due to the high earth leakage
current, and the drive motor must be
connected to an appropriate safety earth.
3. Ensure all incoming supplies are isolated
before working on the equipment. Be
aware that there may be more than one
supply connection to the drive.
4. There may still be dangerous voltages
present at power terminals (motor output,
supply input phases, DC bus and the
brake, where fitted) when the motor is at
standstill or is stopped.
5. For measurements use only a meter to IEC
61010 (CAT III or higher). Always begin using
the highest range.
CAT I and CAT II meters must not be used on
this product.
6. Allow at least 5 minutes for the drive's
capacitors to discharge to safe voltage levels
(<50V). Use the specified meter capable of
measuring up to 1000V dc & ac rms to confirm
that less than 50V is present between all
power terminals and between power terminals
and earth.
7. Unless otherwise stated, this product must
NOT be dismantled. In the event of a fault the
drive must be returned. Refer to "Routine
Maintenance and Repair".
WARNING! - Ignoring the following may result in injury or damage to equipment
SAFETY
Where there is conflict between EMC and Safety requirements, personnel safety shall
always take precedence.
•Never perform high voltage resistance
checks on the wiring without first
disconnecting the drive from the circuit
being tested.
•Whilst ensuring ventilation is sufficient,
provide guarding and /or additional safety
systems to prevent injury or damage to
equipment.
•When replacing a drive in an application
and before returning to use, it is essential
that all user defined parameters for the
product’s operation are correctly installed.
•All control and signal terminals are SELV,
i.e. protected by double insulation. Ensure
all external wiring is rated for the highest
system voltage.
•Thermal sensors contained within the motor
must have at least basic insulation.
•All exposed metalwork in the Inverter is
protected by basic insulation and bonded to
a safety earth.
•RCDs are not recommended for use with
this product but, where their use is
mandatory, only Type B RCDs should be
used.
EMC
•In a domestic environment this product
may cause radio interference in which
case supplementary mitigation measures
may be required.
•This equipment contains electrostatic
discharge (ESD) sensitive parts. Observe
static control precautions when handling,
installing and servicing this product.
•This is a product of the restricted sales
distribution class according to IEC 61800-3.
It is designated as “professional equipment”
as defined in EN61000-3-2. Permission of
the supply authority shall be obtained before
connection to the low voltage supply.

Introduction
The Encoder Option Module is compatible with the AC30V range of
drives, with firmware version 1.5 or later. It offers compatibility with a wide
range of encoders from many manufacturers.
Using this module enables the AC30V to operate in closed-loop speed
control. Alternatively the encoder input may be used as a speed setpoint,
with the drive operating in open-loop (volts / Hz) mode.
Understanding the Product Code
The Encoder Option Module product code is 7004-XX-YY.
Product Code Features available
7004- -0004 1 x Incremental Pulse Encoder

AC30V Encoder Option
Motor Thermistor
The motor thermistor input provides a means of monitoring motor
temperature in order to protect the motor from a potentially damaging high
temperature.
By default the drive will trip if the motor exceeds a user-defined
temperature threshold thereby preventing the motor temperature from
rising further.
Once tripped, the user can attempt to reset the trip at any time. However
if the motor temperature is still above the trip threshold, the trip cannot be
reset.
Refer to the Chapter 10 in the AC30V product manual (HA501718U002)
for information on trips, possible causes, and how to reset them. A motor
thermistor fault is identified in that manual as ID13 (Motor Overtemp).

AC30V Encoder Option
Incremental Pulse Encoder
The incremental pulse encoder feature enables closed-loop speed control
in the AC30V range of drives. An incremental pulse encoder provides
position feedback to the drive relative to an arbitrary starting position. The
drive’s processor can use the encoder position history to calculate motor
speed.
Encoders are available in many forms, both mechanically and electrically.
The mechanical form is selected by the user according to the application.
The electrical form should be chosen to be compatible with the 7004-04-
00. Suitable encoders will conform to the specification below:

Note 1:
The encoder power supply is fully isolated, from the drive’s internal
circuits, and from the encoder inputs on X24 terminals 01 to 04.
Note 2:
In some applications that have a long cable between drive and
encoder, the supply voltage drop along the cable may become
excessive, and the voltage received at the encoder might drop below
the encoder’s specification. This is most likely with 5V encoders. In
this case, the user should provide a local power supply, or choose an
encoder with a wider supply range.

Fault protection
No damage will be caused by overload or
short circuit. It may be necessary to cycle
power to the drive or temporarily disconnect
the encoder to recover from a fault.
Isolation
The encoder supply is galvanically isolated
from the drive and from the encoder input
terminals. Isolation is functional only,
intended to eliminate ground loops. It is not
a safety isolation barrier.
