*1 The speed-position switching control (ABS mode) can be used only when the control unit is "degree".
*2 When "Speed control 10  multiplier setting for degree axis function" is valid, the setting range is 0.01 to 20000000.00 (degree/min).
*3 Time from accepting the positioning start signal until BUSY signal turns ON.
*4 Use cables with outside diameter of 1.3 mm (0.05 inch) or shorter to connect 40 cables to the connector. In addition, consider the
