2. Enable preheating via multi-input terminals (Function B)
Set Pr.02-72 and Pr.02-73 (50% in the diagram) not equal to zero and set MFI=69, and MFI=
ON, then Function B takes priority to enable / disable preheating on the motor drive. At the
same time, enabling preheating by parameters is automatically invalid. If, at this moment, the
motor drive is already STOP, the preheating function is enabled to output DC current and the
MFO (Output Command of Preheating) is ON (MFO=69). The sequence of preheating goes
from OFF (5 seconds) to ON (5 seconds). When the motor is in operation (RUN), the
preheating function is OFF even it is enabled. Meanwhile, MFO is OFF (MFO=69) and the
preheating is enabled when the motor drive stops.
