Forward/Reverse Disable
This parameter Enables/Disables the Forward Run or Reverse Run
mode.
If either direction is disabled (box checked), commands received for the
disabled direction will not be recognized.
If both directions are disabled (both boxes checked), the received
direction command will determine the direction of the motor rotation.
Settings:
0 — Permit All
1 — Disable Reverse Run
2 — Disable Forward Run
3 — Direction by Command Permitted

Scan Rate
Program
Protection
Retry/Restart
In the event of a momentary power outage, the output signal of the drive
will cease. Upon restoration of power, the drive will output a low-level
signal that will be used to determine the rotation speed of the rotor.
The low-level signal will start scanning the motor and decrease until it
reaches 0.0 Hz or it matches the signal produced by the turning rotor.
Once the rate of rotation is determined, the drive will provide the normal
output to engage the motor from its present speed.
This parameter determines the rate at which the scanning signal goes to
0.0 Hz. See
for additional information on this parameter.

Lock-on Rate
Program
Protection
Retry/Restart
After a momentary power outage, the ASD may have to startup into a
spinning motor. The Lock On Rate is the difference between the time
that the RPM of the motor is determined by the ASD and the time that
the ASD outputs a drive signal to the motor.
See
for additional information on this parameter.

Search Method
Program
Protection
Retry/Restart
In the event of a momentary power outage, this parameter may be used
to set the starting point (frequency) of the scanning signal that is used to
determine the rotor speed or this parameter may be used to select the
method used to search for the speed of the rotor. See
and
for
additional information on this parameter.
