8 Safety instructions 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.
Intended audience The manual is intended for the people who are responsible for commissioning and using the FEN-01. 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.
Hardware description 11 Hardware description Contents of this chapter This chapter contains a short description of the FEN-01 TTL Encoder Interface module.
12 Hardware description The FEN-01 TTL Encoder Interface The FEN-01 offers an interface for two TTL encoder connections, one with commutation signals and PTC support. It also offers a TTL encoder output for emulation purposes and two digital latch inputs for position latching.

The shields of sockets X31 and X32 and plug X33 are connected to chassis. The fixing screw connects the chassis to ground. Compatibility FEN-01 is compatible with the following encoders. • TTL incremental encoder, 1...65535 pulses/rev, supports reference mark •...
Installation 15 Installation Contents of this chapter This chapter contains instructions on installing the TTL Encoder Interface module. WARNING! Follow the safety instructions given in this guide and in the drive's hardware manual.
16 Installation Setting the supply voltage WARNING! Selecting the wrong supply voltage may damage or break the encoder. A selectable supply voltage is provided for the TTL encoders' input. A +5.5 V or a +24 V voltage for either TTL encoder can be selected by vertically mounted jumpers as described by the following figure.
Installation 17 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.

Installation 21 General encoder wiring guidelines The encoders should be connected to the encoder interface module with a shielded instrumentation cable, preferably with twisted pairs. See the encoder manual for additional requirements. To prevent the encoder inputs from being disturbed, the cable shield must be connected to the chassis.
22 Installation TTL encoder input (X31) ■ The cable should have minimum 4 cable pairs. A fifth cable pair shared between Vcc an 0V pins allows for a longer cable. VCC_ENC_1 COM_C VCC_ENC_1 OPTIONAL COM_C Cable pair Connecting plug pin number Signals name Notes number...
Installation 23 TTL encoder input with commutation signal support (X32) ■ The cable should have minimum 8 cable pairs. An extra pair shared between Vcc and 0 V allows for a longer cable. VCC_ENC_2 COM_B COM_B SENSOR Signals name Connecting plug pin Notes Cable pair number number (9-pins)

24 Installation WARNING! You can connect a motor temperature sensor to the encoder module only if there is double or reinforced insulation between the live parts of the motor and the sensor. The module does not provide a safe isolation from the drive. Refer to the drive manuals for more information.
26 Installation Digital inputs for position latching (X34) ■ DI1+ DI1- DI2+ DI2- COM_C Cable pair Signals name Connecting header pin Notes number number (6-pins) +24V_C COM_C DI_1+ DI_1- DI_2+ DI_2- Note: Do not route the encoder cables parallel to power (e.g. motor) cables.
The encoder output channel that leads when the drive runs Forward should be connected to FEN-01 input A, the output channel that trails to FEN-01 input B. The zero reference output channel (usually marked 0, N or Z) needs to be connected...
This chapter contains instructions on starting up the Encoder Interface module. Programming The FEN-01 is programmed through drive parameters. These parameters must be checked and adjusted according to the encoder data sheet. For further information, see the drive Firmware Manual.
Interface module. Diagnostic LEDs The FEN-01 is equipped with two diagnostic LEDs. The STATUS LED describes the status of the FEN-01 and the ENC ST LED the status of the encoders. Description of the LED signals is presented below. Colour...
