For occasionally repeated load capability of 200% with a frequency repeated load capability of 175% on motors rated 3/4 HP/RPM and less with standard speed ranges listed on pages 2.4 – 2.29 and on motors rated larger than 3/4 HP/RPM at base speed only, add 10% and refer to Wolong for effect on frame size. Occasionally repeated loads are defined as one-minute duration or less and are not considered as part of the regular duty cycle. Occasionally repeated loads are considered as commutation limits rather than heating limits. Frequently repeated loads are defined as one-minute duration or less repeated such that the RMS current does not exceed rated current over any five-minute period.
