New Program Parameters
P1-01 DC Filter Rise amount per scan B B B B
DC Filter Rise
P1-01= 0.01 Vdc
The DC Filter Rise amount will be added to the DC bus filter when the DC bus voltage
exceeds the value of the DC bus filter + P1-03: Deadband. This value will be added at
a rate of 20 times a second. Using the default value results in a rate of 0.20 Vdc per
second.
P1-02 DC Filter Fall amount per scan B B B B
DC Filter Fall
P1-02= 0.50 Vdc
The DC Filter Fall will be subtracted from the DC bus filter when the DC bus voltage is
below the value of the DC bus filter - P1-03: Deadband. This value will be subtracted at
a rate of 20 times a second. Using the default value results in a rate of 1.00 Vdc per
second.
P1-03 DC Filter Deadband amount B B B B
Filter Deadband
P1-03= 10.0 Vdc
The dead band is the +/- amount that the DC bus must change before the DC bus filter
will be changed. This parameter provides a means of preventing OVP corrections for
normal DC bus fluctuations.
