02 : FW pulse train and RV pulse train
[P014]
Stop position during orientation
Input value is 4 time of the requested stop position (pulse numbers).
<Example>
If you want to stop the motor at 15 pulses after Z pulse is given;
[P014] = 15 * 4 = 60
[P015]
Orientation speed
Low frequency is recommended to be set (1~few Hz for example), so to get stable performance of stopping.
[P016]
Orientation direction
Set the direction during orientation.
[P017]
Completion range of positioning
SJ300 keep performing positioning until the actual stop position is inside this range.
[P018]
Delay time between Completion of positioning and output of the completion signal (POK)
s This is nothing to do with the actual
motor performance, but just a delay
time of POK output signal issue.
