B--65245EN/02
HANDLING
58
[Operation]
The servo amplifier unit exclusive--ORs EBUF with EBS Y. If the
result of exclusive ORing is 1, the servo amplifier unit behaves as
follows:
A) When the function code command is of a t ype to be buffered
before execution.
1. If the function code command buffer of the servo amplifier
unit is available, the servo amplifier unit receives the
function code command at the function code command
buffer.
2. If the function code command buffer of the servo amplifier
unit is unavailable, the servo amplifier unit 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
immediatel y without being buffered
1. The servo amplifier unit 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 unit indicates that it has accepted a function code
command. Because the result of exclusive--ORing EBUF and EBSY
becomes 0, i t 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 unit.
(3) Function code
[Classification]
Output signal <Yy+5>
[Function]
The host specifies the function code command to be executed.
[Operation]
The servo amplifier unit behaves as directed by the function code
command when receiving it.
See ”Direct command function details” for details.
(4) Command data
[Classification]
Output signal <Yy+6 to Yy+15>
[Function]
The host provides data for a function code command.
[Operation]
The servo amplifier unit behaves as directed by the function code
command when receiving it.
See ”Direct command function details” for details.
(5) Response data
[Classification]
Input signal <Xx+7 to Xx+15>
[Function]
A) The servo amplifier unit returns the result of function code
command execution.
