A.12 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)
A.13 Single-phase Operation
When operating with a single-phase supply (TUB-x/230 only), the voltage drop must be
considered. Voltage drop can be calculated using the following equation:
Vout (Max Phase to phase) = 0.85*[ Vsupply (AC) - Vdrop]
