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.
When RY(n+2)1 is turned on, the point table No. or speed command
data set in remote register RW
When it is set to the servo amplifier, the respond code indicating
normal or error is set to RW +2. At the same time, Speed command
rn
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.
