
Enable preheating: When Pr.02-72 and Pr.02-73 are NOT set to zero.

Preheating function A: If Pr.07-72 and Pr.07-23 are set before the motor drive stops operation
(STOP), preheating is enabled right after the motor drive stops. However, if Pr.07-72 and
Pr.07-73 are set after the motor drives stops operation, preheating is not enabled. Preheating is
enabled only when the motor drive stops again or restarts.

Preheating function B: When the motor drive is in operation (RUN) or stops operating (STOP),
set Pr.02-72 and Pr.02-73 between 1–100% and set MFI = 69 and MFI = ON. Preheating is
enabled whenever the motor drive stops; no matter the motor drive is in operation (RUN) or stops
operating (STOP).

Preheating priority: if preheating function A and B are both enabled, function B takes priority.
Sequential Diagram of the Preheating Function:
1. Setting parameters to enable preheating (Function A)
Set Pr.02-72 and Pr.02-73 not equal to zero (50% in the diagram) and stop running the motor
drive, then preheating is enabled to output DC current. At the same time, MFO (Output
Command of Preheating) is ON (MFO=69). Once the drive is rebooted, the preheating function
is enabled right away. 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.
