Table 11.8-4 Braking resistors (10%ED type) for HHD specification
Standard
applicable
motor (kW)
[HP]
Maximum braking torque (%)
Continuous braking
(100% braking torque)
Repetitive braking
(each cycle is 100 s or less)
Discharge
withstand
current rating
(kWs)
Average
allowable loss
(kW)
The 10%ED type is not equipped with a function for outputting temperature detection signals, and
therefore it is necessary to specify electronic thermal overload relay function (function code F50, F51,
F52) settings for braking resistor protection.
(Note) □ in the inverter type is replaced by a letter of the alphabet.

S (basic type), E (type with built-in EMC filter)
