How to fix Err14 (module overheat) reported frequently on Inovance DC Drives?

If Err14, indicating module overheat, is frequently reported, it may be due to several reasons. First, the carrier frequency setting might be too high; try lowering it (F0-15). Second, the cooling fan could be damaged, or the air filter might be blocked; in this case, replace the fan and clean the air filter. If neither of these resolves the issue, the components inside the AC drive may be damaged (thermal coupler or others), and you should contact the agent or Inovance for technical support.
