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.
1.3 Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.
2. Introduction The IT210 is a universal interface using with incremental measuring systems.
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.
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. These determine the input/output mode, the input and output format, as well as settings of the Z Pulse.
5. Progarmmable A/B Divider 5.1. Level converter A/B Pulse (A/B Divider: All OFF) 1024 512 256 8 128 32 16 8 4 7 2 2 Divider [A/B] DIL6 (Left 3-pole) 1 2 3 1 1 DIL5 (Left 8-pole) 3 4 5 6 64 If the A/B pulse have to be switched unchanged from the input to the output (no division, no change in length and position), then the DIL switch position listed below must be chosen. A level conversion is only possible if the input mode (A/B 90 ° or A/B dir) corresponds to the output mode.
5.3. Setting the A/B Divider (at A/B Dir to A/B 90°) The division ratio for the A/B pulses is set at the DIL switches DIL5 and DIL6. The switch positions use a binary code like shown in the subsequent list. (DIL1/6 = ON, DIL1/7 = OFF).
5.4. Setting the A/B divider (for all other modes) The division ratio for the A/B pulses is set at the DIL switches DIL5 and DIL6. The switch positions use a binary code like shown in the subsequent list. (DIL1/6 = OFF, DIL1/7 = X).
5.5. Setting to zero the A/B divider with ZERO_A Signal If the DIL switch DIL1/8 is set to OFF, the divider is reset immediately and remains as long as a high level at the ZERO_A control input is applied. The A/B pulse can be trimmed by switching. A/B, 90 ° signals can cause illegal states when the ZERO_A is switched on and off. In the case of A/B dir Signals, the reset is also done at the same time.
6. Programmable Z Divider 6.1. Pegel conversion Z Puls (Z Divider: all OFF) If the Z pulse have to be switched unchanged from the input to the output (no division, no change in length and position), then the DIL switch position listed below must be chosen.
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) 4 5 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. A division with rest causes that the Z pulse at the output can fluctuate around an input or output period.
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). DIL1 Front Narrow Z puls e (1/4 output- or input-period) 8-pole 4 5 OFF ON The Z pulse is generated from the input signal A/B. Each input period generates one count for the Z divider.
