The Voltage Settings
1. Adjust Voltage: The + (P) and
–
(N) sides of the hydraulic servo motor controller are the DC power
source of the control unit. Therefore, after wiring and before operation, it is very important to set the
voltage of the control unit according to the input voltage of the hydraulic servo motor controller.
This setting will affect the state of activation voltage of the control unit. The following table shows
the state address of individual voltage actions.
