F604
Emergency Off DC Injection Time
Program  Protection
This parameter determines the time that the DC Injection braking is applied to
the motor if DC Injection is selected at F603.
Output Phase Failure Detection
Program  Protection
This parameter Enables/Disables the monitoring of each phase of the 3-phase
output signal (U, V, or W) of the ASD. If either line is missing, inactive, or not of
the specified level for one second or more, the ASD incurs a trip.
Note: Autotune checks for phase failures regardless of this setting.
Settings:
0 — No Detection (Disabled)
1 — First Start (Enabled at Startup and Retry)
2 — Every Start (Enabled at Run Command and Retry)
3 — During Run (Enabled During Run)
4 — Start + Run (Enabled at Startup and During Run)
5 — Auto-Restart (Enabled Detects an ALL-PHASE Failure ONLY - Will Not
Trip, Restarts At Reconnect)
Overload Reduction Starting Frequency
Program  Protection
This parameter is primarily used with V/f motors. It is used to reduce the starting
frequency at which the Overload Reduction function begins and, thus, overloads
at a lower current level. This function is useful during extremely low-speed motor
operation.
This function is useful when used on loads such as fans, pumps, and blowers that
follow the square reduction torque characteristic.
The default overload time is 300 seconds at 150% ASD output; this time may vary
as a function of the magnitude of the overload.
ASD Input Phase Failure Detection
Program  Protection
This parameter enables the 3-phase input power phase loss detection feature. A
loss of either input phase (R, S, or T) results in a trip.
Settings:
0 — Disabled
1 — Enabled
