load (normal duty). The overload rate represents an acceptable load amount that exceeds rated
load, and is expressed in a ratio based on the rated load and the duration. The overload capacity on
the S100 series inverter is 150%/1min for heavy loads, and 120%/1min for normal loads.
• The current rating differs from the load rating, as it also has an ambient temperature limit. For
derating specifications, refer to 11.8 Continuous Rated Current Derating on page 372.
• Current rating for ambient temperature at normal load operation.
[Ambient temperature versus current rating at normal load]
• Guaranteed carrier frequency for current rating by load.

Motor Operation
The 2
nd
motor operation is used when a single inverter switch operates two motors. Using the 2
nd
motor operation, a parameter for the 2
nd
motor is set. The 2
nd
motor is operated when a multi-
function terminal input defined as a 2
nd
motor function is turned on.

In.65–71 Px Define
Set one of the the multi-function input terminals (P1–P5) to 26 (2
nd
Motor) to
display M2 (2
nd
motor group) group. An input signal to a multi-function terminal
set to 2
nd
motor will operate the motor according to the code settings listed
below. However, if the inverter is in operation, input signals to the multi-function
terminals will not read as a 2
nd
motor parameter.
Pr.50 (Stall Prevent) must be set first, before M2.28 (M2-Stall Lev) settings can be
used. Also, Pr.40 (ETH Trip Sel) must be set first, before M2.29 (M2-ETH 1min) and
M2.30 (M2.ETH Cont) settings.
