Chapter 9
Sets the time that the inverter remains in its power loss state before the Power
Loss fault (fault 3) is issued.
If the Power Loss fault is not enabled using the inverter Fault Config 1 parameter
(238), the value of Power Loss Time (185) has no effect on the detection of or
response to a power loss condition.
When set to a non-zero value, selects the change in DC Bus Voltage level at
which the Power Loss occurs.
This value of this parameter is ignored unless one of the digital inputs is
configured to the Pwr Loss Lvl function using the inverter Digital Inx Sel
parameters (361...366).
In Liquiflo 2.0 drives, this parameter should not be changed from its default, and
the digital inputs should not be configured to the Pwr Loss Lvl function.
Selects the source for control of drive direction.

ATTENTION: Setting parameter 190 to 0 or 1 may cause unwanted motor
direction. Verify driven machinery cannot be damaged by reverse rotation
before changing the setting of this parameter to 0 or 1. Failure to observe this
precaution could result in damage to, or destruction of, equipment.
