Input Error 1
When the Drive Prohibition Input
Selection (3504 hex) was set to 0, both the
Forward Drive Prohibition Input (POT) and
the Reverse Drive Prohibition Input (NOT)
turned ON. When object 3504 hex was set
to 2, either the Forward Drive Prohibition
input or the Reverse Drive Prohibition
input turned ON.
Check for any problems with the switches,
wires, and power supplies that are
connected to the Forward Drive
Prohibition input or the Reverse Drive
Prohibition input. In particular, check to
see if the control signal power supply (12
to 24 VDC) turned ON too slowly.

Input Error 2
When object 3504 hex was set to 0,
EtherCAT communications were
interrupted and either POT or NOT was
ON, an operation command (such as a
trial run or FFT) was received from the
CX-Drive. Conversely, POT or NOT
turned ON while operation was being
performed for a CX-Drive operation
command.

Connect the battery power supply, and
then clear the absolute encoder.
Unless the absolute encoder is cleared,
