Page 8: Product Overview
Product overview Product overview KL2521-xxxx - Introduction Fig. 1: KL2521 1 Channel Pulse Train Output Terminal The KL2521-xxxx output terminals change the frequency of a binary signal and output it (electrically isolated from the K-bus). The frequency is preset by a 16 bit value from the automation device. The output stage of the KL2521-0000 is RS422-compatible. -
Page 9: Kl2521-Xxxx - Technical Data
Process image In the delivery state the KL2521 terminal occupies 3 bytes in the process image. The mapping of the KL2521 can be set by means of the controller or by the Bus Coupler's configuration interface using the Beckhoff KS2000 configuration software. -
Page 10: Ramp Function
Product overview Operation modes In addition to the FM (frequency modulation) operation mode, the KL2521 can also be used to control stepper motors with pulse-direction control (frq. cnt pulse mode). Incremental encoder simulation is another operation mode. It is possible to connect the terminal output directly to an incremental encoder input, with which many servo drives and frequency converters are equipped. -
Page 11: Travel Distance Control
Product overview 2.3.2 Travel distance control If the travel distance control function is active (Feature.9), then a rising edge at Control.2 will result in drive to a fixed counter value. This value must previously be entered in register 0 (low word) and in register 1 (high word) at runtime. -
Page 12: Output Pattern
Product overview 2.3.3 Output pattern The pulse pattern is output through channels A and B. The operation mode is configured with the feature register R32. The operation modes differ primarily between the positive logic (modes 0, 1, 2) and the negative logic (modes 4, 5, 6). -

Page 15: Fig. 5 Disassembling Of Terminal
Mounting and wiring Disassembly Fig. 5: Disassembling of terminal Each terminal is secured by a lock on the mounting rail, which must be released for disassembly: 1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doing so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of the bus terminal block easily without excessive force. -

Page 18: Fig. 7 Standard Wiring
Mounting and wiring • The High Density Terminals (HD Terminals) include electronics and connection level in a single enclosure and have advanced packaging density. Standard wiring (ELxxxx / KLxxxx) Fig. 7: Standard wiring The terminals of ELxxxx and KLxxxx series have been tried and tested for years. They feature integrated screwless spring force technology for fast and simple assembly. -
Page 19: Wiring
Mounting and wiring The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal point without tools. -

Configuration Software KS2000 Configuration Software KS2000 KS2000 - Introduction The KS2000 configuration software permits configuration, commissioning and parameterization of bus couplers, of the affiliated bus terminals and of Fieldbus Box Modules. The connection between bus coupler / Fieldbus Box Module and the PC is established by means of the serial configuration cable or the fieldbus. Fig. 20: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline. - Page 28 Configuration Software KS2000 Commissioning The KS2000 software facilitates commissioning of machine components or their fieldbus stations: Configured settings can be transferred to the fieldbus modules by means of a download. After a login to the terminal station, it is possible to define settings in couplers, terminals and Fieldbus Box modules directly online. The same high-level dialogs and register access are available for this purpose as in the configuration phase.
