2.3.2 Changing the Addresses of Fixed Signals

The fixed devices can be allocated arbitrarily with the following parameters.
The parameters #2073 to #2075 are valid when "#1226 aux10/bit 5" is set to "1".
When the parameters #2073 to #2075 are valid, do not set the same device number.
If the same device number exists, an emergency stop occurs. However, no device number check is performed for an axis to
which a signal (R248, R272) that ignores the fixed signal is input.
When the arbitrary allocation is valid, the fixed signals can be used as other signals.

Specify whether to enable the arbitrary allocation parameter for the origin dog
and H/W OT.
0: Disable arbitrary allocation. (Fixed device)
1: Enable arbitrary allocation. (Device specified by the parameter)
Under the standard specifications, the origin dog signal is assigned to a fixed de-
vice. When it is desired to assign the origin dog signal to a position other than the
fixed device, specify the input device in this parameter.
 This parameter is enabled in the following conditions.
NC axis: When "#1226 aux10/bit5" is set to "1".
PLC axis: When "#1246 set18/bit7" is set to "1".
 When this parameter is valid, do not set the same device number. If the same
device number exists, an emergency stop occurs. However, no device number
check is performed for an axis to which a signal that ignores the near-point dog
signal (R272) is input.
Under the standard specifications, the OT (+) signal is assigned to a fixed device.
When it is desired to assign the OT (+) signal to a position other than the fixed
device, specify the input device in this parameter.
 This parameter is enabled in the following conditions.
NC axis: When "#1226 aux10/bit5" is set to "1".
PLC axis: When "#1246 set18/bit7" is set to "1".
 When this parameter is valid, do not set the same device number. If the same
device number exists, an emergency stop occurs. However, no device number
check is performed for an axis to which a signal that ignores the OT signal
(R248) is input.
Under the standard specifications, the OT (-) signal is assigned to a fixed device.
When it is desired to assign the OT (-) signal to a position other than the fixed
device, specify the input device in this parameter.
 This parameter is enabled in the following conditions.
NC axis: When "#1226 aux10/bit5" is set to "1".
PLC axis: When "#1246 set18/bit7" is set to "1".
 When this parameter is valid, do not set the same device number. If the same
device number exists, an emergency stop occurs. However, no device number
check is performed for an axis to which a signal that ignores the OT signal
(R248) is input.
