Mitsubishi GX works instruction help

Hi everybody, I am working on a packaging machine that communicates with 2 servo drives and need a little help understanding the instruction. I have cone through our documentation and tried contacting the OEM (Japan) but have had no reply. The instruction i am interested in is
[MOVP K0 G1517]
I understand the MOVP K0 but don't understand the G1517 part.
One of our engineers thinks this is the instruction to control the servo. Is this Mitsubishi's modbus communication?

This may help - though I'm not exactly sure which CPU you're using, posting programs would help
