If the converter is not running and the protection signal becomes active, protection measure is
applied as follows:
● If frost protection speed p29623 ≠ 0 (default 0), frost protection is activated by applying the
specified speed to the motor.
● If frost protection speed p29623 = 0 and condensation protection current p29624 ≠ 0,
condensation protection is activated by applying the specified current to the motor.
