Please refer to "
Appendix A:Braking
" about
the
wiring of braking resistor.
When the DC bus voltage is higher than the set voltage which caused by fast decreasing, the
internal braking unit turn on. If the DC bus voltage falls below the brake voltage 5V, the braking
unit closed. Please set the braking voltage level properly according to different grade inverter.

100%
100% relates to the rated current
of
the driven motor. When P0-0 =100%, the protection level is
150% 1 minute. Then the inverter displays oL2 alarm and blocks output and the motor stops
freely.
Motor overload protection
time
calculation:
Overload time (S) = 2700/ (( motor current/ motor overload protection current) * 100-105)
The overload alarm can be
reset
by STOP/ RST key on keyboard, multi-function terminal
(
H0-XX
= 20) and communication are reset.
The overload protection count value of the motor can be monitored by
U3-00
(overload
cumulative percentage) which is the Max. value of the motor overload or over-torque and the
inverter overload or over-torque. The motor overload protection as shown in
