Function/Interface
Power supply input terminal (12 to 24 VDC) for sequence
inputs.
Input for emergency stop.
When this signal is enabled and pin 1 is not connected to
pin 2, an Emergency Stop Input error (alarm code 87) oc-
curs. Set this signal to be enabled or disabled in the Emer-
gency Stop Input Setting (Pn041) (Factory default:
Enable).
feedback pulse counter.
The position data is obtained the moment the input is
turned ON.
Minimal signal width must be 1 ms or more.
This input is used as external general-purpose input 1.
When the Torque Limit Selection (Pn003) is set to 3 or 5,
this signal input selects the torque limit. (For details, refer
to the description of the Torque Limit on page 5-16.)
Forward and reverse rotation overtravel input.
Pn004 chooses between enable and disable.
Pn044 sets the function assignment for pins 19 and 20.
Pn066 selects the operation.
Connect the origin proximity input signal in the origin
search operation.
Pn042 changes the logic of the sensor.
This input is used as external general-purpose input 0.
This input is used as external general-purpose input 2.
