8.1.4 Rated Elevator Load Setting
Function Code Parameter Name Setting Range Default Unit Property
F0-05
Rated elevator load 300–9999 1000 kg
★
It is used to set the rated elevator load. This parameter is used for the anti-nuisance function.
8.1.5 Frequency Setting
Function Code Parameter Name Setting Range Default Unit Property
F0-06
Maximum frequency 20.00–99.00 50.00 Hz
★
It is used to set the maximum output frequency of the system. This value must be larger than the rated
motor frequency.
8.1.6 Reduction of Motor Noise and EMI
Function Code Parameter Name Setting Range Default Unit Property
F0-07
Carrier frequency 0.5–16.0 6.0 kHz
★
It is used to set the carrier frequency of the controller.
The carrier frequency is closely related to the motor noise during running. When it is generally set above
6 kHz, mute running is achieved. It is recommended to set the carrier frequency to the lowest within the
allowable noise, which reduces the controller loss and radio frequency interference.
When the carrier frequency reduces, the following factors also increase:
●
Harmonics of output current
●
Motor power loss
●
Motor temperature rise
When the carrier frequency increases:
●
Motor power loss and temperature rise declines.
●
Power loss, system temperature rise and interference increase.
Adjusting the carrier frequency will exert inuences on the aspects listed in the following table.
Table 8-1 Inuences of carrier frequency adjustment
Carrier frequency Low High
Motor noise Large Small
Output current waveform Bad Good
Motor temperature rise High Low
Controller temperature rise Low High
Leakage current Small Large
External radiation interference Small Large
