  • Page 10: Overview

    1. OVERVIEW 1. OVERVIEW This user's manual contains the specifications, and operation/programming procedures for VS-QA262B-M2R (*1) which is to be used in combination with a Mitsubishi Electric corp. MELSEC-Q Series programmable controller. VS-QA262B combines a rotary position sensor to detect the position of the machine being controlled. VS-QA262B is used with the ABSOCODER sensor (rotary type).
  • Page 11 Current Position Detection Function VS-QA262B's current position detection function detects the current position using an ABSOCODER sensor. Conventionally, this was detected using an incremental format encoder in conjunction with a counter unit. The above conventional method has several disadvantages; origin-point return is necessary when power supply is interrupted due to power failure, etc.

  • Page 12: Features

    1.1 Features VS-QA262B has the following features: (1) Absolute position detection: Rotational position is detected by an absolute position detection method. Even when a power outage, etc., occurs, the correct position of the ABSOCODER sensor will be instantly detected when power is turned back ON. (2) High resolution: The 32-turn rotary-type ABSOCODER sensor (the MRE Series) offers a resolution factor of 4096 divisions per 1 turn of the sensor shaft.

  • Page 13: Definitions

    1.2 Definitions (1) ABSOCODER ABSOCODER is the generic name given to the NSD-developed position sensor which detects rotational/linear displacement, speed, and acceleration, using an absolute position detection method with a digital (or analog) output. ABSOCODER consists of two main components:...

  • Page 20 (4) Error detection (X5 [X9]): This signal comes ON when any of the ‘X4 [X8]’ signal comes ON, or when any of the errors shown section 6.1 occur. ‘X5 [X9]’ will go OFF after the cause of the error has been corrected, and the ‘Y1C’ (error reset signal) has been turned ON by the sequence program.

  • Page 21: Buffer Memory

    3.5 Buffer Memory VS-QA262B contains a buffer memory which is used for data communication with the PLC CPU. The buffer memory configuration and content is shown below. Data readout of all areas can be executed by the sequence program. Buffer memory space is provided for 2 axes (same content). Addresses 0 to 702 are for Axis 1, and addresses 1000 to 1702 are for Axis 2.

  • Page 22: Input Status Storage Area

    3.5.3 Input status storage area This area is used to store the input status of the Current position setting command (Y13 [Y16]). The input status is stored as follows: Address 6 [1006] Current position setting command (1) Current position setting command status When the Current position setting command is ON, '1' is stored.

  • Page 23: Axis Enabled/Disabled Setting Area

    3.5.7 Axis enabled/disabled setting area This area determines whether to enable or disable a particular axis. When buffer memory address 702 is set to "99", the axis 1 will be disabled. When buffer memory address 1702 is set to "99", the axis 2 will be disabled. This area can be written at any time by the sequence program.
