11.3 The Selection of Braking Resistor and the Unit
11.3.1 The selection of dynamic braking resistor
Resistor values shown in the following table is calculated on the basis of 150% of rated braking torque, 5% ED 1).
Power rating of resistor should be doubled for resistor frequency 10% ED use. Additional braking unit should be installed
for above SV 300iV5-2 / SV300iV5-4.

9 (1): ED is based on 100 seconds.
9 (2): Rated capacity is based on the self-cooling.
11.3.2 Wiring of the temperature sensor on braking resistor
Temperature sensor is attached in the LSIS braking resistors to prevent the fire.

One of the multi-function input
terminals (P1 ~ P7) should be set to
‘External Fault Signal b Contact’.
Contact is normally ON at the
ambient temperature and is OFF in
case of over-temperature.
