・The kind of thermistor specified in [Cb-40] must be attached to [TH]
terminal.
If [Cb-40] =01 or 02, error level must be set in [bb-70].

・In vector control, when speed surpass “maximum
speed”×[bb-80] for more than the [bb-81] time, it will result in an
error.

・In vector control, if the time which the speed deviation (absolute of
[dA-12]-[dA-08] ) is greater than the "maximum frequency setting" x
[bb-83] exceeds [bb-84] value , an error or warning will occur and the
output terminal 041[DSE] turn ON.

・The setting of [bC112] enables subtraction of the motor's thermal
integration value. If [bC113] is lowered from the initial value, the risk
of motor burnout may increase, so set it appropriately according
to the heat dissipation characteristics of the motor.
(Example 1)
When [bC111] =00, Inverter rated current: 64A, [bC110] =64(A),
Base frequency [Hb104]=50Hz or 60Hz, Output frequency=20Hz
・In case of output frequency = 16Hz (base=50Hz) or 20Hz (base = 60hz),
the reduction scale is ×0.8, then the inverter will trip when the output
current of 120%(150%×0.8) flows continuously within 60s according
to the curve.
