LSIS LSLV0055H100-4COFN - Pre-Heating Function

Learning Advanced Features
210
In the graph above, Pipe Break occurs if the feedback is smaller than the value caculated
by multiplying the two values set at PID-04 and PRT-61(PID-04 x PRT-61) at the inverter‘s
maximum output (when PID output is the maximum set value, or the inverter is running at
the frequency set at DRV-20).
5.20 Pre-heating Function
This function uses current to heat up the motor or pump to avoid the motor or the pump
freezing when they are not in operation.

Description
AP2-48 Pre Heat
Curr
Sets the current to be used for initial heating. Sets the current to motor
no-load current % value.
AP2-49 Pre Heat
Duty
Sets the duty (time) for the current to be used for initial heating, from 10
seconds to % value.
AP2-50 DC Inj Delay
T
Sets a certain delay time to prevent from an over current trip that may
occur when a DC input is performed after the inverter Free-Run stop.
IN-65–71 P1–7
Define
Performs the Pre Heat function if the Pre Heat (44) terminal is set.
The initial heating function continually operates when the set multi-function input terminal is
on and until the inverter command is on. If an inverter command is input while the initial
heating function is operating, the inverter starts operation immediately.
