CC-Link IE Field Network communication

DI/O (Input: 11 points excluding EM2 (Forced stop 2), output: 8 points) RS-422/RS-485 communication (Note 3) DI/O (Input: 11 points excluding EM2 (Forced stop 2), output: 6 points) RS-422 communication (Note 4) Positioning by specifying the point table No. (255 points) Set in the point table. Setting range of feed length per point: -999999 to 999999 [×10 STM μm], -99.9999 to 99.9999 [×10 STM inch], -999999 to 999999 [pulse], Setting range of rotation angle: -360.000 to 360.000 [degree] (Note 2) Set in the point table. Setting range of feed length per point: 0 to 999999 [×10 STM μm], 0 to 99.9999 [×10 STM inch], 0 to 999999 [pulse], Setting range of rotation angle: 0 to 999.999 [degree] (Note 2) Set the acceleration/deceleration time constants in the point table. Set the S-pattern acceleration/deceleration time constants with [Pr. PT51]. Set the acceleration/deceleration time constants in the point table. Set the S-pattern acceleration/deceleration time constants with [Pr. PC03]. Signed absolute value command method, incremental value command method Set by parameters or external analog input (0 V DC to +10 V DC/maximum torque) Point table No. input, position data input method Each positioning operation is executed based on the position/speed commands. Varying-speed operation (2 to 255 speeds), automatic continuous positioning operation (2 to 255 points) automatic continuous operation to the point table selected at start, automatic continuous operation to the point table No. 1 Inching operation is executed with a CC-Link IE Field Network communication function based on speed commands set with a parameter. Inching operation is executed with input signal or serial communication function (Note 3) based on speed commands set with a parameter. Manual feeding is executed with a manual pulse generator. Command pulse multiplication: select from ×1, ×10, and ×100 with a parameter. Dog type (Rear end detection, Z-phase reference), Stopper type (Stopper position reference), Count type (Front end detection, Z-phase reference), Dog type (Rear end detection, rear end reference), Count type (Front end detection, front end reference), Dog cradle type, Dog type last Z-phase reference, Dog type front end reference, Dogless Z-phase reference 0 V DC to ±10 V DC/0% to 200% Set by parameters or link devices
