Caution:
Take caution when DB resistor is used over its Watt rating. Fire may
result from resistor overheat. When resistor having heat detection sensor
is used, sensor output can be used as external trip signal in multi-
function input.
1 ED is limited as the setting in H 76.
H76: set the resistor operating rate(%ED) in one sequence of operation. Continuous
usage reate is Max 15 sec and usage signal is not issued over 15 sec.

Where,
T_acc: Acceleration time to reach a setting freq.
T_steady: Time for constant speed operation at setting freq.
T_dec: Time to decelerate to lower freq. than that in constant speed
or time to stop from freq. in constant speed.
T_stop: waiting time at a stop before operation is resumed.
