Speed acceleration /
deceleration selection When RYnD is turned off, acceleration and deceleration time constant
set in the point table No.1 will be selected.
When RYnD is turned on, acceleration and deceleration time constant
set in the point table No.2 will be selected. RYnD RYnD *3
Speed command execution
demand When RY(n+2)1 is turned on, the point table No. or speed command
data set in remote register RW
wn
+6 is set.
When it is set to the servo amplifier, the respond code indicating
normal or error is set to RW
rn
+2. At the same time, Speed command
execution completion (RX(n+2)1) turns on.
By setting parameter No.PC50, you can choose the timing when the
speed command data of remote register is reflected.
Refer to section 17.7.2 for details.
