Page 66 0.0% 5.5.4 V/F (SVPWM) control mode TD350 VFD also carries built-in V/F (SVPWM) control function. V/F (SVPWM) mode can be used in cases where mediocre control precision is enough. In cases where a VFD needs to drive multiple motors, it is also recommended to adopt V/F (SVPWM) control mode.
Page 67 Square-type Output frequency TD350 VFD also provides multi-point V/F curve. Users can alter the V/F curve outputted by VFD through setting the voltage and frequency of the three points in the middle. The whole curve consists of five points starting from (0Hz, 0V) and ending in (fundamental motor frequency, rated motor voltage).
Page 68 Motor oscillation often occurs in SVPWM control in large-power drive applications. To solve this problem, the TD350 series VFD sets two function codes to control the oscillation factor, and users can set the corresponding function code based on the occurrence frequency of oscillation.

The program of this method is simple, and the calculation is fast, but the ROM space occupied is large.
Page 277 TD350 Series VFD Communication protocol LSB of CRC MSB of CRC T1-T2-T3-T4 (transmission time of 3.5 bytes) The value in START and END is "T1-T2-T3-T4 (transmission time of 3.5 bytes)", indicating that the RS485 needs to stay idle for at least the transmission time of 3.5 bytes. An idle time is required to distinguish on message from another to ensure that the two messages are not regarded as one.
