●
Table 2-4 is a guiding data, user can select different resistor value and power according to actual
situation.
●
Selection of braking resistor is based on the motor generation power in actual application system,
it is related with system inertia, deceleration time, potential load energy, it is decided by user’s actual
situation.
●
The greater the inertia of system, the required speed deceleration is shorter, the braking is more
frequent, so the braking resistor require a bigger power small value of resistor.
2.9 Routine Repair and Maintenance of Inverter
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of the
devices in the inverter, which may cause potential fault of the inverter or reduce the service life of the
inverter. Therefore, it is necessary to carry out routine and periodical maintenance on the inverter, it
must be regularly maintenance for every 3~6 months.
