Manufacturer: ABB

 

Part catalog: FEN-31

 

Product type: encoder

The product description

 

The driver and adjacent devices must be properly grounded. Do not attempt to do any work on the electric drive. After turning off the power, always allow the intermediate circuit capacitor 5 to work on the converter before discharge time, motor or motor cable. It is good practice to check (with a voltage indicator) that the driver is actually being discharged to start working

 

As before. The motor cable terminal of the transmission device is at a dangerously high voltage when the main power is applied, regardless of motor operation. There may be dangerous external voltage control circuits inside the inverter, even if the driving power is turned off. Take due care when working on the device.

 

Overview This chapter contains a short description of the FEN-31 HTL encoder interface. Fen-31 HTL encoder interface FEN-31 is an encoder for the interface between the control panel and the HTL. It supports various types of HTL encoders. PTC or KTY temperature sensors can be connected to the FEN-31 interface connection. FEN – 31

 

TTL encoder conforms to RS-422 standard analog output and two digital inputs. It also includes cable fault diagnosis for certain HTL encoder types. Viewing the Driver Firmware

 

There are two supply voltages X81 on pins 4 and 5 of the connector. Only one of them can be used to provide an encoder. This is done by placing a jumper on connector X81 to select the supply voltage as shown below. The following supply voltages are optional :+15 VOLTS DC 20% 200 mA (Max. +24 Volt DC 20% 200 mA

 

(Maximum value.) You can also connect an external 10 — 24 volt DC power supply to pins 4 and 5. In that case, the jumper must have been removed.

 

Note: Before installing the module, set the supply voltage as described above for the jumper. The FEN-31 is inserted into the optional slot of the drive. See the drive The hardware manual for more information. Module with plastic retaining clips and a f * * k. The screws also provide cable shielding for the ground connection to the module and interconnect the GND signal

 

Module and drive. When installing the module, signals and power are connected to the drive through a 20 pin connector automatically manufactured. Setup procedure: Carefully insert the module into the optional slot until the retaining clip locks the module in place. Attach the screws (included) to the bracket. Note: Screws are properly installed to meet EMC requirements

 

Requirements and correct operation of the module.

module

A module, also known as a component, is a collection of program statements (a collection of program code and data structures) that can be individually named and independently complete certain functions. It has two basic characteristics: external characteristics and internal characteristics. External features refer to the interface of the module connected with the external environment (that is, the way other modules or programs call the module, including input and output parameters, referenced global variables) and the functions of the module; Internal characteristics refer to the characteristics of the internal environment of a module (that is, the local data and program code of the module).
