*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
amount of current to be used and select appropriate cables.
