) a t a d n g i S : e m a n l a n g i S ( 6 t i B
<Description>
• Sign signal for the position command data which is sent from the CPU module
Sign = “0”: Forward (the direction to increase the current position value)
“1”: Reverse (the direction to decrease the current position value)
Position command data is 32-bit length with sign (+).
) d n a m m o c e t i r w a t a D : e m a n l a n g i S ( 7 t i B
<Description>
• This command writes the data of set values in the register which is selected at the rising edge at which this signal
changes from “0” to “1.”
While the data write command is “1,” response to the command becomes “1.”
Register select
(PC == > MP1)
Set value data
(PC == > MP1)
Write command
(PC == > MP1)
Response to write command
(PC <== MP1)
“1” “1”
“1” “1”
• Writing in each register is possible at the desired timing.
Precautions:
• In the pulse generation mode, deceleration point detection during automatic operation is not normally performed if
data in any of the following registers is rewritten during pulse output.
Register name : Base frequency register
: Acceleration/deceleration register 1
: Speed multiplication register
: Deceleration point register
• In the pulse generation mode, while the speed change command is “1,” the data write command is ignored, except
for the following registers. If writing is attempted, the response to the write command becomes “1,” but no data is
updated.
Valid writing registers: pulse count setting buffer lower, middle and upper and buffer 16 register.
In the position command mode, the speed change command is ignored.
