Parameter b2-04 also serves the function of affecting the length of time DC Injection to stop (b1-03 = “2: DC Injection to Stop”) will
occur.

b2-09 Motor Pre-Heat Current
Setting Range:
0 ~ 100%
Factory Default: 0%
A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and
prevent condensation. Parameter b2-09 determines the percentage of the iQpump drive rated output current that will be used for the motor
pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions.
Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat Input (H1-0x = 60). Check with the
motor manufacturer to determine the maximum acceptable current level the motor can withstand when stopped. Be sure not to exceed the
motor manufacturers recommended level.
