Description/Notes
Pulse frequency 0-7
[0]
Sets the pulse frequency (from 2 to 16 kHz) and PWM
mode. If silent operation is not absolutely necessary,
the losses in the inverter as well as the RFI emissions
can be reduced by selecting lower pulse frequencies.
0/1 = 16 kHz
2/3 = 8 kHz
4/5 = 4 kHz (400 V default)
6/7 = 2 kHz
Even numbers = normal modulation technique.
Odd numbers = lower loss modulation technique used
when operating mainly at speeds above 5 Hz.
Note: Selecting 8KHz or 16KHz may reduce the
output current rating.
Motor current
limit (%)
0-200
[100]
Defines the motor overload current as a % of the
nominal motor current (P083) allowed for up to one
minute.
With this parameter, the motor current can be limited
and overheating of the motor prevented. If this set
value is exceeded for one minute; the output frequency
is reduced until the current falls to that set in P083.
The inverter can be made to trip by using the relay in
conjunction with P074.
Note: The maximum value that P086 can be set to is
automatically limited by the rating of the inverter.
