    1. Safety Instructions and Responsibility 1.1 General Safety Instructions This operation manual is a significant component of the unit and includes important rules and hints about the installation, function and usage. Non-observance can result in damage and/or impairment of the functions to the unit or the machine or even in injury to persons using the equipment! Please read the following instructions carefully before operating the device and observe all safety and warning instructions! Keep the manual for later use.

  • Page 4: Installation

    For placement, wiring, environmental conditions as well as shielding and earthing/grounding of the supply lines the general standards of industrial automation industry and the specific shielding instructions of the manufacturer are valid. Please find all respective hints and rules on www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and Earthing]”.

  • Page 5: Introduction

    2. Introduction The IT210 is a universal interface using with incremental measuring systems. The device allows the solution of the following problems: • Level conversion (RS-422, HTL single ended, HTL differential, TTL and vice versa) • Division of two-track A / B pulses with adjustable ratio 1: 1 to 1: 2048 •...

  • Page 6: Terminal Assignments And Connections

    4. Terminal Assignments and Connections The input pulses are connected to the screw terminals X4. The unused inputs must remain open (HTL Single Ended as opposed to HTL Differential), or possibly be completed (unused Z-track in RS-422 or HTL Differential format). On the X4 screw terminal 9, 8, an auxiliary voltage of + 5.5 V / 250 mA is available for the encoder supply.
  • Page 7 The green LED signals operational readiness (power switched on). The yellow LED signals an input error. (RS-422 or HTL Differential only) An HTL Error Signal (input error, only for RS-422 or HTL differential) is available on the X3 screw terminal 1. (Error = low) Basic settings: At the front DIL switches DIL1 and DIL2, some basic presets have to be made when commissioning.

  • Page 13: Location And Width Of The Z Pulse

    6.3. Location and width of the Z pulse If the DIL switch DIL4 of the Z divider is completely set to OFF, the Z Pulse is forwarded from the input directly to the output (see pegel converstion Z Puls). All pictures in this section assume that the A/B divider is set to 8. The Z Pulse is divided according to its divider (additionally DIL2/1 on OFF, ZIN is used, Z dividers not complete on OFF).

    DIL1 Front Narrow Z pulse (1/4 output-periode) 8-pole (Only applicable to output signals A/B 90°, DIL1/7 = OFF) ON OFF The pulse width at the output corresponds to ¼ period of pulse width at the output. In this operation mode, only division ratios may be used, which together with the A/B divisor deliver clear and completely results.

    6.5. Automatic generation of a Z pulse If the DIL switch DIL2/1 is set to ON, a Z pulse can be automatically generated. The Z input is ineffective and does not need to be connected (Z divider not completely set on OFF).
