Sequential Diagram of the Preheating Function:
Setting Parameters to Enable Preheating (Function A)
Set Pr02-72 and Pr02-73 not equal to zero (Diagram 50%) and stop running the motor drive,
then the preheating will be enabled to output DC current. In the meantime, MFO (Output
Command of Preheating) will be ON (MFO =69). Once repower on, the preheating function will
be enabled right away. Besides, the sequence of preheating goes from OFF(5 seconds) to
ON(5 seconds). When the motor is in operation (RUN), the preheating function will be off even it
is enabled. Meanwhile, MFO is OFF (MFO =69) and the preheating will be enabled when the
motor drive stops.
Enable Preheating via Multi-Input Terminals (Function B)
Set Pr02-72 and Pr02-73 (Diagram 50%) not equal to zero and set MFI=69, MFI = ON,
then this Function B has the priority to enable/ disable the preheating on the motor drive.
In the meantime, the preheating by parameters is automatically ineffective. If, at this
moment, the motor drive is already not in operation (STOP), the preheating will be
enabled to output DC current and MFO (Output Command of Preheating) will be ON
(MFO =69). Besides, the sequence of preheating goes from OFF(5 seconds) to ON(5
seconds). When the motor is in operation (RUN), the preheating function will be off
even it is enabled. Meanwhile, MFO is OFF (MFO =69) and the preheating will be
enabled when the motor drive stops.
