Page 7: Introduction
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: 4096 •... -
Page 8: Electrical Connections
Electrical Connections The terminal screws should be tightened with a slotted screwdriver (blade width 2mm). DC Power Supply The device is supplied with a DC voltage between 9 ... 30 VDC via terminals 1 and 2 of X1. The current consumption depends on the level of the supply voltage and the settings and is approx. 35 mA without load from the sensor supply and additional on the extracted encoder current at the auxiliary voltage output. -
Page 9: Incremental Inputs A, /A, B, /B, Z, /Z
Incremental Inputs A, /A, B, /B, Z, /Z At terminal 2 ... 7 of X4, 3 pulse inputs are available for HTL / TTL / RS422 signals. The unused inputs must be open (HTL single ended vs. HTL differential) or terminated (unused Z track in RS- 422 or HTL differential format). -
Page 10: Control Inputs
Control Inputs Two control inputs with HTL PNP characteristics are available at terminals 2 and 3 of X2 and are used for resetting the internal dividers Unconnected control inputs are always “LOW”. All inputs are designed to receive impulses from an electronic impulse source. Notice for mechanical switching contacts: When exceptionally mechanical contacts are used, please connect an external capacitor between GND (-) and the corresponding input (+). -
Page 11: Error Ausgang
Error Ausgang An HTL error signal (input error, only with RS-422 or HTL differential) is available at the X3 screw terminal 1. (Error = low). The error is triggered by a line fault (short circuit or line break) by the input lines A, / A, B, / B or Z, / Z. -

Page 17: Setting To Zero The A/B Divider With Zero_A Signal
Setting to zero the A/B divider with ZERO_A Signal The divider will only be reset in the zero phase of the output signals AOUT and BOUT and will remain as long as the signal is attached. This prevents the miscounting of subsequent circuits. This function can only be applied to A/B 90°, it is independent of the divider ratio. -

Page 19: Location And Width Of The Z Pulse
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 level conversion 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). -
Page 20: Independent Z Divider
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. -
Page 21: Automatic Generation Of A Z Pulse
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). -
