Specifications
Control I/O Signal Connections and External Signal Processing for Torque Control
*1. A cable equipped with a battery is not required if a backup battery is connected.
Note 1. The inputs of pins 8, 9 and 26 to 33, and outputs of pins 10, 11, 34, 35, 38 and 39, can be changed via parameter
settings.
Note 2. Pins 13, 20, 42 and 43 represent signals which are applicable when an absolute encoder is used.
Note 3. If pins 21, 22, 49, 48, 23, and 24 are used for the encoder output, use pin 25 (ZGND) to wire the ground.
Note 4. It is not necessary to wire input pins that are not being used.
