Safety instructions
Contents of this chapter
The chapter contains the warning symbols and the safety instructions which you must
obey when you install or connect an optional module to a drive or converter. If you
ignore the safety instructions, injury, death or damage can occur. Read this chapter
before you start the installation.
Overview
This chapter states the general safety instructions that must be followed when
installing and operating the FEN-11.
In addition to the safety instructions given below, read the complete safety instructions
of the specific drive you are working on.
These warnings are intended for all who work on the drive. Ignoring the instructions
can cause physical injury or death, or damage the equipment.
General safety instructions
WARNING!
All electrical installation and maintenance work on the drive must be carried
out by qualified electricians only.
The drive and adjoining equipment must be properly earthed.
Do not attempt any work on a powered drive. After switching off the mains, always
allow the intermediate circuit capacitors 5 minutes to discharge before working on
the frequency converter, the motor or the motor cable. Check (with a voltage tester)
that the drive is in fact discharged before beginning work.
1
Safety instructions 7

The motor cable terminals of the drive are at a dangerously high voltage when mains
power is applied, regardless of motor operation.
There can be dangerous voltages inside the drive from external control circuits even
when the drive mains power is shut off.
Exercise appropriate care when working on the unit.
These warnings are intended for all who work on the drive. Ignoring the instructions
can cause physical injury or death, or damage the equipment.
For complete safety instructions see the drive manuals.

Introduction
Contents of this chapter
This chapter introduces this manual.
Intended audience
The manual is intended for the people who are responsible for commissioning and
using the FEN-11. The reader is expected to have a basic knowledge of electrical
fundamentals, electrical wiring practices and how to operate the drive.
Before you start
It is assumed that the drive is installed and the drive power supply is switched off
before starting the installation of the extension module. Ensure that all dangerous
voltages connected from external control circuits to the inputs and outputs of the
drive are switched off.
In addition to conventional installation tools, have the drive manuals available during
the installation as they contain important information not included in this manual.
The drive manuals are referred to at various points of this document.

Hardware description 11

The FEN-11 Absolute Encoder Interface
The FEN-11 offers an interface for an absolute encoder with PTC/Pt1000/KTY support
and TTL encoder connection and a TTL encoder emulation output. It also supports
two digital inputs for position latching.

￭Absolute Encoders
• Sin/cos incremental encoder, 1...65535 periods/rev, also supports reference mark
and sin/cos commutation signals
• Endat 2.1 and 2.2 with and without sin/cos signals
• HIPERFACE
• SSI, with and without sin/cos signals
• Tamagawa, 17/33-bit Smart Abs and 17-bit Smart Inc.
￭TTL Encoders
• TTL incremental encoder, 1...65535 periods/rev, supports reference mark (zero
pulse).

Installation
Contents of this chapter
This chapter contains instructions on installing the Absolute Encoder Interface module.
WARNING!
Follow the safety instructions given in this guide and in the drive's hardware
manual.

Installation 17

Setting the supply voltage
WARNING!
Selecting the wrong supply voltage may damage or break the encoder.
A selectable supply voltage is provided for the absolute encoder's and the TTL encoder's
input. A +5.5 V or a +24 V voltage for a TTL encoder and a +5.5 V or a +8 V voltage for
an absolute encoder can be selected by vertically mounted jumpers as described by
the following figure.
+24 V +5.5 V +5.5 V +8 V
TTL Encoder Absolute Encoder
Note: If an external power supply is used, the appropriate jumper must be removed.
Note: If another FEN interface's TTL emulation output is connected to TTL input, the
appropriate jumper must be removed.
18 Installation

Mounting
WARNING!
Before installation, do the electrical safety precautions given in section Safety
instructions.
Note: Before mounting the option module, set the supply voltage jumpers as described
above.
The option module is to be inserted into the option slot of the drive. See the drive
hardware manual for more information.
The module is held in place with plastic retaining clips, a locking tab and one screw.
The screw also provides the earthing of the cable shields connected to the module
and interconnects the GND signals of the module and the drive.
On installation of the module, the signal and power connection to the drive is
automatically made through a 20-pin connector.
Numbers in brackets refer to the layout drawing in section layout.
Mounting procedure:
1. Pull out the locking tab (8)
2. Insert the module carefully into the option slot until the retaining clips lock the
module into position
3. Push in the locking tab (8)
4. Fasten the screw (included) to the stand-off.
If you need to remove the adapter module after it has been installed into the drive,
use a suitable tool (e.g. small pliers) to carefully pull out the locking tab.
Note: Correct installation of the screw is essential for fulfilling the EMC requirements
and for proper operation of the module.
