4.10. Pulse-Width Modulation (PWM)
Feature Details
PWM resolution 12-bit
PWM switching frequency on the load 2/ Ts (factory default 22 kHz on the motor)
4.11. Heat Sink Specifications
The following table indicates the RMS output power when operating the Bassoon at nominal
DC bus voltage:
Bassoon 1/230 3/230 6/230
RMS output power without heat sink (%) 80 4 0 20
If the input voltage is lower, the RMS output current without a heatsink is higher.
Two types of heat sinks are recommended for ensuring maximum continuous output power of
the drive:
• Finned heat sink
• L-Shaped heat sink
