Technical Manual for EA350 Analog Pulse Type Servo Driver V101 8.3 d2-xx Product information query parameters The servo driver type is displayed. d2-00 hundreds place represents the factory parameter, which shall be provided upon requesting technical support. Other parameters in this group will not be further elaborated. 8.4 d3-xx Real-time monitoring parameters Parameters d3-05~d3-14 have the same meaning with corresponding function parameters in group d0, but they are refreshed once every 1ms and thus cannot be accurately identified by naked eyes. When real-time data needs to be acquired by the upper computer, the data can be read by communication.
64-bit motor position data comprising d3-18 and d2-20 displays the position of the absolute value encoder (encoder unit) corresponding to the mechanical zero point, which is only valid in the absolute position mode and can be used when needed. 1. Mechanical zero point is the encoder position obtained by the stop position of the motor after homing minus the set value of Pb-10. 2. Note that Pb-10 is a command pulse unit and needs to be converted into an encoder unit through the electronic gear ratio. 3. This mode works only when the absolute type encoder is used and P8-06=1, that is, the absolute position mode is enabled.
Caution ☞ 64-bit motor position data comprising d3-22 and d2-24 displays the offset of the current motor position relative to the mechanical zero point and the encoder unit, which can be used when needed.
