11.5 Signals and wiring

POINT
Input signals of the servo amplifier are valid even when the MR-D01 has been
connected. When the same input devices have been assigned to the servo
amplifier and MR-D01 and both input signals are turned on, the input signal that
has turned on first is enabled. Even though turning off one of the input signals
that have been turned on is attempted, the input signal cannot be turned off.
Refer to the following table for details. The following table shows ST1 (Forward
rotation start) as an example.
