Note: Refer to 5.3.3 Input Circuit Signal Allocation for details on input terminals.
Input signals are allocated as shown above and displayed on the panel of
the servo amplifier or the digital operator. They are indicated by the
ON/OFF status of the vertical parts of the seven-segment displays located
in top and bottom rows. (The horizontal segments are not used here). These
vertical segments turn ON or OFF relative to the state of the corresponding
input signals (ON for “L” level and OFF for “H” level).
Examples
• When /S-ON signal is ON (Servo ON at “L” signal)
8 7 6 5 4 3 2 1
The bottom segment
of number 1 is lit
• When /S-ON signal is OFF
8 7 6 5 4 3 2 1
The top segment
of number 1 is lit
• When P-OT signal operates (Operates at “H” signal)
8 7 6 5 4 3 2 1
The top segment
of number 3 is lit.
