B--65245EN/02
HANDLING
62
[Operation]
When the servo amplifier unit is in the wait state, it sets the wait signal
WAT to 1. If the WFN signal is set to 1 under this condition, the servo
amplifier unit and host behave as follows:
1. The servo amplifier unit resets t he wait signal WAT to 0. Upon
detecting that the WAT becomes 0, the host resets the WFN to 0.
The servo amplifier unit exits from the wait state and executes the
next command.
(1 6) Memory registration signal INPF
[Classification]
Output signal <Yy+3#7>
[Function]
The host can store function code commands into the m emory of the
servo amplifier unit and control memory operation according to the
data in the memory. If buffering type function code, such as a position
command, is issued with INPF set to 1, it is registered into memory
instead of being executed. Up to 32 blocks can be registered. Once a
series of registration operations has been completed, the INPF is reset
to 0. This command is erased when the power is switched off. It is
necessary to register it in memory before memory operation is used.
If the INPF is set to 1 when function code is already registered in
memory, the function code is cleared from memory, allowing new
function code to be registered.
[Operation]
If buffering type function code is issued with INPF set to 1, it is stored
into memory instead of being executed.
(17)Memory registration in--progress signal INPFO
[Classification]
Input signal <Xx+3#7>
[Function]
The servo amplifier unit indicates, to the host, that it is in memory
registration mode. When the INPFO signal is 1, a buffering type
function code command, such as a positioning command, is stored
into memory instead of being executed.
[Input condition]
The signal becomes 1 when:
1. The host sets the INPF signal t o 1 to specify memory registration
mode, and the servo amplifier unit enters memory registration
mode.
The signal becomes 0 when:
1. The host resets the INPF signal to 0 to release memory
registration mode, and the servo amplifier unit exits from
memory registration mode.
(18)Interface switch signal DRC
[Classification]
Output signal <Yy+1#5>
[Function]
The host informs the servo amplifier unit of the interface type
(peripheral equipment control interface or direct command interface)
to be used.
[Operation]
When the DRC signal is 0, the slave runs using the peripheral
equipment control interface. When it is 1, the slave runs using the
direct command interface. The servo amplifier unit also sends the
interface status notification signal DRCO ((19) of Section 2.3.14) to
