[Classification]
Input signal <Xx+1#0> (peripheral equipment control only)
[Function]
After writing response data (Xx+3 to Xx+6), the servo amplifier unit
inverts this signal for notification to the host.
[Operation]
The servo amplifier unit exclusive--ORs ABSWT with ABSRD. If
the result of exclusive--OR is 0, the servo amplifier unit writes
response data (Xx+3 to Xx+6), and inverts this signal.
[Classification]
Output signal <Xx+1#4> (peripheral equipment control only)
[Function]
After reading response data (Xx+3 to Xx+6), the host inverts this
signal for notification to the servo amplifier unit.
[Operation]
The host exclusive--ORs ABSWT with ABSRD. If the result of
exclusive--OR is 1, the host reads response data (Xx+3 to Xx+6), and
inverts this signal.
[Classification]
Input signal <Xx+2#4 to #5> (peripheral equipment control only)
[Function]
The servo amplifier unit indicates the contents of response data.
[Input condition]
The servo amplifier unit sets the contents of data being output in the
response data by using a combination of signals as indicated in the
table below.
DSP2 DSP1 Response data
1 1 Coordinate or motor current value
1 0 Current position number (ATC, point number)
NOTE
The setting of parameter No. 20 is used for distinction
between a coordinate and motor current value.
