Protection function
• Blown fuse
• Cooling fin overheat
• Abnormal operation of IGBT
(Switching element)
• Braking resistor overheat
When detecting abnormalities described left,
the operation of the IGBT in the DB unit is
stopped, and an alarm is output to the inverter
unit
Cooling system Self-ventilation (forced ventilation when using option fans)
Installation location
Indoor
Altitude of 1000m or less
Free from corrosive gas. dust and direct sunlight
Ambient temperature −10℃ to +50℃
∗ 1) Duty factor (%ED) and braking time are converted into the condition of deceleration braking as shown
below.
Duty factor
%ED=( T1/T0 ) X 1 00%
T1 : Braking time (10s)
T0 : Repetitive period (100s)

The rated current value is an r.m.s value of the current in TD section.
∗ 2) When using the option fans, the duty factor (%ED) is calculated making the braking time (T1) 30s.
