4. DIRECT COMMANDSHANDLING
131
The host can register and execute up to 32 blocks of direct commands in
the internal memory of the servo amplifier unit.
NOTE
One block consists of one instruction command which is a
direct command.
The host registers up to 32 blocks of direct commands in the internal
memory of the servo amplifier unit by means of the procedure explained
below.
(1) The host sets memory registration signal INPF [2.3.14 (16)] to 1.
(2) After confirming that memory registration in--progress signal INPFO
[2.3.14 (17)] has been set t o 1, the host registers direct commands in
the servo amplifier unit through EBUF/EBSY control.
(3) Upon the completion of registration, the host sets memory
registration signal INPF to 0.
CAUTION
The registered blocks are all erased when the INPF signal
state is changed from 0 to 1. Also, the registered blocks are
all erased when the power is disconnected.
NOTE
An attempt to register more than 32 blocks results in the
issue of alarm 70. (” ” appears on the LED indicator.)
The host operates and executes registered direct commands by means of
the procedure explained below.
(1) Select AUTO mode. (MD1 = 1, MD2 = 0, MD4 = 0 [2.3.4 (1)])
(2) Change the status of automatic operation start signal ST [2.3.10 (1)]
from 1 to 0. When the level of the ST s ignal falls, buffering operation
starts. (It is also possible to start operation when the ST signal l evel
rises by param eter setting (bit 7 (STON) of parameter No. 3)).
NOTE
1 After the last block has been executed, operation is halted.
To perform operation again from the first block, cause a
reset to locate the first block, then start operation by using
the ST signal. A reset causes the top of the registered
blocks to be located.
2 During buffering, switching the ST signal state from 0 to 1
causes a single--block stop. To restart operation, change
the ST signal state from 1 to 0.
