130 - 150 - 185 - 200 - 220 - 250 - 300 - 315 ...
• 0015 (1.5HP) is the rating that will have four digits for output Identification and
only one for RPM.
• 0045 (4.5kW) is the rating that will have four digits for output identification and
only one for RPM.
Frame
The frame number must be included as long as the number of remaining
characters allows.
Example:
143T, 143TC, 405T, 405TS, 184JP.
