Mitsubishi Motion PLC instruction Command

Hellow everybody
Can anyone please explain the below instruction?

DP.SFCS H3E1 K1
DP.SFCS H3E1 K15
DP.SFCS H3E1 K20
DP.SFCS H3E1 K150


Please see the attached picture of a sample position control program.
Machine Details
Machine Name :Refrigerator Door Plate Machine
CPU:Q170MCPU
Servo Motor:MR-J3_B

I've not used this system but if you Google the manual IB-0300135, it says that the instruction is the start request of the specified SFC motion program.
I would imagine these SFC motion programs reside in the controllers (guessing).
Hopefully some one else will answer and clarify.

Thank you Mr. Nehpets
