Description
The switching frequency of drive is most usually set to 8 kHz. For some special cases, the switching frequency can be increased to 16 kHz.
The change of the switching frequency is only possible for the 230 power supply (VBUSBAL = 0).
The set parameter is the variable DPWM.
- DPWM = 0: 8kHz
- DPWM = 1: 16 kHz
- DPWM = 2: 8 kHz without power loss reduction (starting 4.32)
Starting with firmware 4.94 the 16kHz mode can also be used at 400 and 480V.
The restrictions (lower currents) are:
601 IPEAK and ICONT have the maximum rating
603-614 400V (VBUSBAL = 1): IPEAK = 55% peak current of the drive, ICONT = 55% of rated current of the drive
603-614 480V (VBUSBAL = 2): IPEAK = 45% peak current of the drive, ICONT = 45% of rated current of the drive
620 400V (VBUSBAL = 1): IPEAK max = 26A and ICONT max = 14A
480V (VBUSBAL = 2): IPEAK max = 22A and ICONT max = 12A
