Parker AC30 series User Manual

3-2 Product Overview
AC30 series Variable Speed Inverter
Power Stack Features
General
Switching Frequency
Minimum 2kHz
Default 2kHz (Frames K, L, M & N), 2.5kHz (Frames H & J), 3kHz (Frame G), 4kHz (Frames D, E & F)
Maximum 12kHz (Frames D, E, F & G), 8kHz (Frames H, J, K, L, M & N)
Derating of output current will apply above the default switching frequency.
Output Frequency
Maximum is Switching Frequency divided by 8. This is limited to 590Hz due to export rules.
e.g. for 4kHz switching frequency it is 4000/8 = 500Hz
Maximum is Switching Frequency divided by 6, in PMAC Motor Closed Loop Control.
If >590Hz is required, please contact your local Parker Sales representative.
