- 62 -
(10) Alarm output state check signal DSALO
[Classification] Input signal <Xx+2#3>
[Function] The servo amplifier module indicates the contents of the response data.
[Input condition] When the signal is 0, a turret, magazine, point number, coordinates, or
motor current value are being output as response data. When the signal
is 1, the number of alarms and the first alarm number are being output as
response data.
2.3.14 Direct Command Function Code and Related Information
(1) Function code command strobe signal EBUF
[Classification] Output signal <Yy+4#7>
[Function] After setting the function code (Yy+5) and command data (Yy+6 to
Yy+15), the host inverts the logical state of this signal to indicate to the
servo amplifier module that the function code is ready for transfer.
[Operation] The servo amplifier module exclusive-ORs EBUF with EBSY. If the
result of exclusive ORing is 1, the servo amplifier module behaves as
follows:
(A) When the function code command is of a type to be buffered
before execution.
1. If the function code command buffer of the servo amplifier
module is available, the servo amplifier module receives the
function code command at the function code command
buffer.
2. If the function code command buffer of the servo amplifier
module is unavailable, the servo amplifier module waits until
it becomes available, that is, rejects reception of the current
function code command.
(B) If the function code command is of a type to be executed
immediately without being buffered
1. The servo amplifier module receives the function code
command at its execution buffer immediately and starts
processing according to the function code command.
(2) Function code command read completion signal EBSY
[Classification] Input signal <Xx+4#7>
[Function] The servo amplifier module indicates that it has accepted a function
code command. Because the result of exclusive-ORing EBUF and
EBSY becomes 0, it becomes possible to issue another function code.
[Input condition] The state of the signal is inverted when a function code command is
received by the servo amplifier module.
(3) Function code
[Classification] Output signal <Yy+5>
[Function] The host specifies the function code command to be executed.
[Operation] The servo amplifier module behaves as directed by the function code
command when receiving it.
