Since Scroll motor is directly coupled to gearbox, parameters corresponding to D3 and D4
(belt roller diameter) must be set to 1. The communication between Scroll drive and Bowl
drive is maintained through DDCS (M/F) link.
Bowl drive parameter settings:
= Bowl
= Value of D1
= Value of D2
Scroll drive parameter settings:
= Scroll
= Backward drive
= Value of D1
= Value of D2
= Gearbox ratio
= Value of D3 = 1
= Value of D4 = 1
