User manual OMRON H8PS

[. . . ] Cam Positioner H8PS Please read and understand this catalog before purchasing the products. Please consult your OMRON representative if you have any questions or comments. Refer to Warranty and Application Considerations (page 32), and Safety Precautions (pages 17 and 18). This Compact Cam Positioner, Popular for It's Ease-of-use, Now Comes with Even Better Functions. · Compact 8-, 16-, and 32-output Models available that are 1/4DIN size at 96 x 96 mm. · High-speed operation at 1, 600 r/min and high-precision settings to 0. 5° ensure widespread application. [. . . ] The output elements may be destroyed, possibly resulting in shortcircuit or open-circuit faults. · Always connect a diode to protect against counterelectromotive force when using an inductive load. Counterelectromotive force may destroy output elements, possibly resulting in short-circuit or open-circuit faults. · Do not install input lines in the same duct or conduit as power supply or other high-voltage lines. · Internal elements may be destroyed if a voltage outside the rated voltage is applied. · Maintain voltage fluctuations in the power supply within the specified range. · Use a switch, relay, or other contact so that the rated power supply voltage will be reached within 0. 1 s. If the power supply voltage is not reached quickly enough, the H8PS may malfunction or outputs may be unstable. · Do not turn OFF the power supply when changing or deleting settings. The contents of the EEPROM may be corrupted. 18 Cam Positioner H8PS Precautions for Correct Use · A cam output will remain ON if the set angles for two steps overlap for the same cam number. Step 1: 120° ON 170° OFF Step 2: 150° ON 210° OFF ON OFF 120° 150° 170° 210° · A step will produce no output if the ON and OFF angle for the step are the same. · The RUN output does not turn ON during programming. RUN/TEST Mode Switch PRGM RUN output ON OFF Note: The RUN output turns ON with the timing shown in the diagram, but it remains OFF when an error occurs. Thus, you can use the output as a timing signal during operation, including trial operation. · Input signals may be accepted, not accepted, or unstable for the following times when the power supply is turned ON or OFF. 1 second is required from the time the power supply is turned ON until outputs are made. Z199) for information on other timing. Power supply ON OFF 0 to 1. 3 s 5 ms 0 to 1 s · Do not subject H8PS Connectors (outputs, Encoder) to more than 30 N of force. · Confirm the waveform of the power supply circuit and install a surge absorber. Surge or noise applied to the power supply may destroy internal elements or cause malfunctions. · Switch the power supply circuit with a device rated at 3. 5 A or higher. · Inrush current of approximately 3. 5 A will flow for a short period of time when the power supply is turned ON. The H8PS may not start if the capacity of the power supply is not sufficient. The EEPROM is written when settings are changed or deleted or when the resolution is changed. [. . . ] Setting Enabled Display yes Description An E24 error will be displayed if the Encoder is not connected correctly in Run Mode or Test Mode. An E24 error will not be displayed even if an Encoder is not connected. CAM STEP Setting Display PRG Enable or disable E24 detection with the ANGLE Keys . yes (Enabled) no (Disabled) Disabled no Note: Default settings are shown in reverse type. 30 Cam Positioner H8PS Self Diagnostic Function The following displays will appear on the main display if an error occurs. If an error occurs, all outputs (including cam, pulse, and run outputs) will be turned OFF. Display e00 e11 e12 e13 e21 e22 e23 e24 Meaning Origin designation data error Memory error: RAM error Memory error: Checksum error CPU error Response speed exceeded Encoder data error Encoder resolution inconsistent Encoder disconnected Recovery method Press the CLEAR Key for at least 3 s.
