Note
(1)
It is not necessary to use option type dynamic braking unit for IS7 0.75~22kW(200V, 400V)
because basically the dynamic braking unit is built in.
(2)
you must refer to dynamic braking unit manual for usage recommended dynamic braking unit
in the table above due to changeable table.
(3)
Resistance/watt/breaking torque/%ED of DB Resistor for Type A DB Unit refer to the table of
