Typographic and iconographic conventions In this guide the following symbols are used: This icon, followed by the word WARNING, is meant to highlight the parts of the text where information of great significance for the user can be found: user must pay the greatest attention to them! Instructions must be followed strictly to guarantee the safety of the user and a correct use of the device. -
Page 5: Preliminary Information
• AQ58S and AQ59H series AQ58S and AQ59H programmable encoders from Lika Electronic and solely sold by Automation Direct are designed to maximize customization and versatility and really allow the operator to get, along with the position information, a complete parametrization and the better configuration that perfectly suit specific needs in a good many applications and machines. -

Page 7: Configuring The Encoder Using The Software Tool
Configuring the encoder using the software tool AQ58S and AQ59H programmable incremental encoder is supplied with software expressly developed and released by Lika Electronic to easily program and configure the device. The software is supplied for free and can be installed in any PC fitted with a Windows operating system (Windows 7 or later). -
Page 8: Connection With The Encoder
AQ58S, AQ59H Two sections can be found in the main page of the configuration interface: • A top section groups the items needful for establishing the connection between the encoder and the interface, the connection buttons as well as the drop-down boxes designed to select the interface type and the series of the encoder to connect;... - Page 9 AQ58S, AQ59H o Standard = Clockwise rotation represents Channel A leads Channel B o Inverted = Counterclockwise rotation represents Channel A leads Channel B Index Length o 90° (gated A, B) o 180° (gated A) Index Position o When ‘set’ is pressed, the Z pulse will be configured at the current position of the shaft.

Page 10: Internal Pos. Register
AQ58S, AQ59H Internal pos. Register It is used to show the value in the internal position register: the current position of the encoder. When you start the program, 0 appears next to this item. Press the START button to start the routine which allows continuous reading and displays the current position: the current position of the encoder appears on the field. -
Page 11: Resolution
AQ58S, AQ59H Resolution This parameter allows the operator to set the custom number of pulses that the encoder will output per each revolution (PPR). Please enter the desired value and then press the ENTER button to confirm. If you set a value that is out of range (lower or greater than allowed), the system automatically sets either the minimum or the maximum value in the range. - Page 12 AQ58S, AQ59H EXAMPLES Here are some examples useful for better understanding the application field of the programmable resolution. We assume that the pulse multiplication factor in the following electronics is x 1. Example 1 Let's assume that the encoder is mounted on the driven draw roller of a slitter and the circumference of the roller is 753 mm.

Page 13: Counting Direction
AQ58S, AQ59H As we know the reduction ratio of the ball screw and gearbox, we can set a suitable resolution to control the motion of the motor precisely and calculate the input speed starting from the known output speed. Example 3 Let's assume that the encoder is used to control the movement of a chain conveyor. -
Page 14: Index Length
AQ58S, AQ59H Index length This parameter allows to set the width of the Index pulse (Z pulse) expressed in electrical degrees. Two options are available and selectable in the drop- down box: 90° (gated A, B) and 180° el (gated A). Please note that the Z pulse having a width of 90 electrical degrees is synchronized with A and B pulses, while the Z pulse having a width of 180 electrical degrees is synchronized with A pulse. -
Page 15: Max Rpm
AQ58S, AQ59H Max rpm Displays the maximum rpm and resulting maximum electrical output frequency available from the encoder. The Max rpm value is calculated by using the programmable resolution entered above and the encoder's maximum electrical output frequency (500kHz). For the maximum resolution setting 16384 PPR, the Max rpm allowed is 1831rpm (500kHz). -
Page 16: Encoder Status
AQ58S, AQ59H If you reverse the formula, you can easily calculate the maximum number of revolutions starting from the value of the counting frequency (as allowed by the encoder, permitted by the subsequent electronics) and the desired number of pulses per revolution: Maximum counting frequency (kHz) * 60 * 1000 RPM = The reversed formula can be very useful -for instance- when you know the... -
Page 17: Diagnostics Page
AQ58S, AQ59H Diagnostics page When you press the ADVANCED DIAGNOSTICS button in the main page, you enter the DIAGNOSTICS page. In this page you can find detailed information on the work status of the encoder. The current status is described in the window in the middle-right side of the page. - Page 18 Ce dispositif doit être alimenté par un circuit de Classe 2 ou à très basse tension ou bien en appliquant une tension maxi de 30Vcc.
