=74
Namely (01001010)2 = (74)10
Hence P8-17 should be set as 74
It’s mainly applied to the setting of Acc/Dec time for each program,
which is preset by binary mode (16 bit). Parameter can be entered only after
the binary value is converted into decimal value.
Take the following settings for example:
Parameter values= (0000000011100100) = (228)
2 10
Hence the P8-18should be set as 228
P9 : Protection Function parameters
These two parameters are mainly applied to the setting of real-
time relay protection of load motor. Effective thermal protection of motor
can be achieved by setting this parameter correctly when rated current of
motor is not matched with rated current of converter. Critical point of
overload protection (motor) = (allowed max. load current / rated current of
motor) * 100%

Over voltage protection function will be enabled so that the
decreasing output frequency of converter can be slowed down if bus voltage
detected by converter while running exceeds the critical point of over voltage
defined by parameter P9-03(in comparison with standard bus voltage); if it’s
detected that the bus voltage is lower than the critical point, converter will
continue to decelerate again.
Due to the influence of inertia load, actual droop rate of motor’s
rotational speed may be lower than droop rate of output frequency while
converter is decelerating; meanwhile, electrodes may feedback electric
energy to converter, which may raise the bus voltage of converter. If no action
is taken in time, stripping may be caused by over voltage of busbar.
Because of excessive load, actual rate of rotational speed rise of
motor may be lower than the rate of output frequency rise while converter is
decelerating; if no action is taken in time, stripping may be caused by over
current.
Over-current protection function will be enabled so that increasing
output frequency of converter can be slowed down if bus current detected by
converter while running exceeds the critical point of over current defined by
parameter P9-05; if it’s detected that output current is lower than the critical
point, converter will continue to accelerate again.
