1. OVERVIEW
This manual describes the VS-212DN specifications and the operation and programming procedures
when the VS-212DN is used together with DeviceNet.
Designed to replace limit switches, the VS-212DN unit features a rotary position sensor which detects the
machine's position. The detected position is then compared with the setting position value, and the
appropriate motor control signals are output accordingly.
The VS-212DN is equipped with the ABSOCODER rotary position sensor. The ABSOCODER features a
magnetic position detection format, and can be used in place of mechanical cam switches, proximity
switches, and limit switches, etc.
This sensor can be used for automatic control of conveyance systems, press machines, and assembly
machines, etc., where position detection is required. Moreover, the VS-212DN permits ABSOCODER
sensors to be connected to 2 axes for simultaneous 2-axes control.
The VS-212DN is used in conjunction with DeviceNet. DeviceNet is a system which permits position and
control data exchanges with a master unit such as a programmable logic controller (hereafter referred to
as "PLC"), etc.
Because all settings can be specified in DeviceNet, an external setting unit is not required.
(If an external setting unit is needed, the VS-T62 or VS-T62B should be used. VS-T62B is the successor
model to VS-T62.)
