7) Actuator driver for Axis No.0 and No.1
8) Actuator driver for Axis No.2 and No.3
9) Actuator driver for Axis No.4 and No.5
One piece of a driver CPU board and one piece of a power stage board make one pair. It is
possible to control two axes with one set. Three classes are available to insert at the
maximum.
Caution: Do not attempt to insert the driver CPU board to position other than the one that
the board was originally inserted to.
The parameter dedicated for the indicated actuator is already written to the driver
CPU board at the purchase order. Proper operation cannot be performed with it
inserted in a wrong position. It is the same for the power stage board. Also, it may
cause such malfunctions as the board being burned down.
