10.2.1.2. Adjusting Home Position Switch and Home Offset Value
l The position of the Home position sensor (a dog or a sensor) must be adjusted properly to perform
Home Return accurately.
l The Home position is determined at the point where the resolver value becomes zero after detection
of HLS input rising edge when motor is running under Home Return near-zero velocity. (The home
position is set to the point that is off-set by HO, if the Parameter HO value is not set to 0 (zero).)
l The resolver has many teeth for detecting its position and the rising edge of HLS is to identify a
tooth out of these teeth. To make precise detection of øZ, the Home limit switch position must be
adjusted so that the HLS input goes high when the switch is at the middle center of the tooth width.
Design the Home limit switch so that it can be adjusted ±1.2° or more in relation to the tooth width.
l Take the following steps to adjust the position of the Home limit switch.
