5.5.24 Condensation protection
When motors are in wet or cold environments, condensation can cause faults to the motors. This risk
can be eliminated by simply increasing the surface temperature of the motor during the work interval.
When the external condensation sensor detects intensive condensation, the VFD injects DC current
into the motor to raise the motor surface temperature to prevent condensation.
To implement the function: Set the S digital input terminal function to 91 to enable condensation
protection. If this terminal is enabled through external signal, the VFD sends DC current and
automatically stops the sending 40s later. If this function needs to be triggered again, re-enable this
function terminal. You can set P96.15 to adjust the DC current proportion.
