Emergency Off
Program
Protection
Emergency Off Settings
This parameter determines the method used to stop the motor in the
event that an Emergency Off command is received and the system is
configured to use this feature.
This setting may also be associated with the FL terminals to allow the FL
relay to change states when an EOFF condition occurs by setting the FL
terminal to Fault FL (all) (see
).
Note:
A supplemental emergency stopping system should be used
with the ASD. Emergency stopping should not be a task of the ASD
alone.
Settings:
0 — Coast Stop
1 — Deceleration Stop
2 — DC Injection Braking Stop
3 — Coast Stop without Tripping
4 — Deceleration without Tripping
5 — DC Injection Braking without Tripping

Emergency DC Braking Control Time
Program
Protection
Emergency Off Settings
When DC Injection is used as a function of receiving an Emergency Off
command
), this parameter determines the time that the DC
Injection braking is applied to the motor.
Direct Access Number —

Parameter Type —
Numerical
Factory Default —
0.10
Changeable During Run —
Yes
Minimum — 0.00

Units — Seconds
Output Phase Failure Detection
Program
Protection
Phase Loss
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, the ASD incurs a trip.
Settings:
0 — Disabled
1 — Enabled (box checked)
Direct Access Number —
F605

Factory Default —
Disabled
Changeable During Run —
No
Overload Reduction Start Frequency
Program
Protection
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.
Direct Access Number —
F606
Parameter Type —
Numerical
Factory Default —
6.00
Changeable During Run —
Yes
Minimum — 0.00
Maximum — 30.00
Units — Hz
