G7 ASD Operation Manual
Electronic Thermal Protection #1
Program
⇒
Motor Parameters
⇒
Motor Set #1
The Motor #1 Electronic Thermal Protection parameter specifies the motor
overload current level for motor set #1. This value is entered as either a
percentage of the full load rating of the ASD or as the FLA of the motor.
The unit of measurement for this parameter may be set to Amps or it may be set
as a percentage of the ASD rating. The name-plated FLA of the motor may be
entered directly when Amps is selected as the unit of measurement (see
F701
to
change the display unit).
Electronic Thermal Protection settings (#1 – #4) will be displayed in Amps if
the EOI display units are set to V/A rather than %.

⇒
Stall
This parameter specifies the output current level at which the output frequency
is reduced in an attempt to prevent a trip. The overcurrent level is entered as a
percentage of the maximum rating of the drive.

Trip Save at Power Down Enable
Program
⇒
Protection Parameters
⇒
Trip Settings
This parameter Enables/Disables the Trip Save at Power Down setting. When
enabled, this feature logs the trip event and retains the trip information when the
system powers down. The trip information may be viewed from the Monitor
screen.
When disabled, the trip information will be cleared when the system powers
down.

Emergency Off Mode Settings
Program
⇒
Protection Parameters
⇒
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
F132
).
Note:
A supplemental emergency stopping system should be used with
the ASD. Emergency stopping should not be a task of the ASD
alone.
Settings:
Coast Stop
Deceleration Stop
DC Injection Braking Stop
Direct Access Number — F603
