SP600 AC Drive User Manual

29 = Pwr Loss Lvl: When the DC bus level in the drive falls below a
certain level, a “powerloss” condition is created in the drive logic.
This input allows the user to select between two different “power
loss” detection levels dynamically. If the physical input is closed,
then the drive will take its power loss level from a parameter. If the
physical input is open (de-energized), then the drive will use a
power loss level designated by internal drive memory, typically 82%
of nominal. If the input function is not configured, then the drive
always uses the internal power loss level.

30 = Prechange En: This input function is used to manage
disconnection from a common DC bus.

If the physical input is closed, this indicates that the drive is
connected to common DC bus and normal precharge handling can
occur, and that the drive can run (start permissive). If the physical
input is open, this indicates that the drive is disconnected from the
common DC bus, and thus the drive should enter the precharge
state (precharge relay open) and initiate a coast stop immediately in
order to prepare for reconnection to the bus.

If this input function is not configured, then the drive assumes that it
is always connected to the DC bus, and no special precharge
handling will be done.

31 - 38 = Reserved

39 = UserSetBit0: 0 = Disabled; 1 = Enabled

40 = UserSetBit1: 0 = Disabled; 1 = Enabled

If either UserSetBit# is not defined, a zero value is used.

Type 2 Alarms

Some digital input programming may cause conflicts that result in a
Type 2 alarm. For example, Digital In1 Sel set to 5 (Start) in 3-wire
control, and Digital In2 Sel set to 7 (Run) in 2-wire control. Refer to
chapter 12 for more information about these alarms. Note that Type
2 alarms will prevent the drive from starting.

Dig In Status (116) indicates the current state of the digital inputs.
