Emergency Off DC Injection Application Time
Program ⇒ Protection Parameters ⇒ Emergency Off Settings
When DC Injection is used as a function of receiving an Emergency Off
command (F603), this parameter determines the time that the DC Injection
braking is applied to the motor.
Output Phase Loss Detection
Program ⇒ Protection Parameters ⇒ Phase Loss
This parameter Enables/Disables monitoring of each phase of the 3-phase
output signal (U, V, or W) of the ASD and provides an error message should
either cease.
OL Reduction Starting Frequency
Program ⇒ Protection Parameters ⇒ Overload
This parameter is used to reduce the start frequency during very low-speed
motor operation. During very low-speed operation the cooling efficiency of the
motor decreases. Lowering the start frequency aides in minimizing the
generated heat.
Motor 150% OL Time Limit
Program ⇒ Protection Parameters ⇒ Overload
This parameter establishes a time that the motor may operate at 150% of its
rated current before tripping. This setting applies the time/150% reference to
the individual settings of each motor (e.g., this setting references 150% of the
F600 setting for the #1 motor).
The unit will trip sooner than the time entered here if the overload is greater
than 150%.
Inrush Current Suppression
Program ⇒ Protection Parameters ⇒ Soft Start
The startup inrush current may be suppressed for up to 2.5 seconds. This
parameter determines the length of the inrush current suppression.
