FH correction function (escaping
triangle drive)
When the feed amount is small and the motor may
possible to start deceleration on the way of
acceleration (triangle drive), this function
automatically lowers the operation speed and escape
this triangle drive.
Counter
COUNTER 1: Specified position counter (28 bits)
COUNTER 2: Mechanical position counter (28 bits)
COUNTER 3: Difference counter (16 bits)
Comparators
3 at 28 bits each
