7-107 2. Absolute systemSupplement OutlineOutline of Absolute SystemWhen you compose an absolute system using an absolute encoder, you are not requiredto carry out homing operation at the power-on, and this function suits very well to such anapplication as a robot.Connect the host controller with the Minas A5 with absolute specifications. (motor withabsolute encoder and driver with absolute spec) and set up the parameter, Pr0.15 to 0 or 2,then connect the battery for absolute encoder to compose an absolute system with whichyou can capture the exact present position information after the power-ON.Shift the system to origin once after installing the battery and clear the multi-turn data byclearing the absolute encoder, then you can detect the absolute position without carryingout homing operation.Via RS232 or RS485 communication, the host controller can connect up to 32 MINAS-A5and capture the present position information as serial data to obtain the absolute positionof each axis by processing. each data.Applicable ModeYou can use all of MINAS A5 series driver in absolute specifications by setting up param-eter. Use the motor which 8th place (designated for rotary encoder specifications) is “S”(7-wire type).Absolute SpecificationsThere are 3 connecting methods of the host controller and MINAS-A5 driver as describedbelow, and select a method depending on the interface of the host controller specs ornumber of axis to be connected. Designate a module ID to Pr5.31 of each MINAS-A5driver when you connect multiple MINAS-A5 in communication to one host controller asshown below.[Parameter Pr5.31]• When you connect each MINAS-A5 to the host separately with RS232 and switch thecommunication individually, designate 0 to 31 to each MINAS-A5. (Max. 31 axis areconnectable.)• When you connect one MINAS-A5 to the host with RS232 and connect each MINAS-A5with RS485, designate 0 to the MINAS-A5 connected with the host, and designate 1 to31 to other MINAS-A5. (Max 32 axis are connectable.)• When you connect MINAS-A5 to the host with RS485, the host is given module ID of 0,and designate 1 to 31 to MINAS-A5. (Max 31 axis are connectable.)M M S8th placeRotary encoder specifications |
