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.
