G7 ASD Operation Manual 155
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 determine s the time that the DC Injection
braking is applied to the motor.
Direct Access Number — F604
Parameter Type — Numeri cal
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.00
Maximum — 10.00
Units — Seconds
Output Phase Loss Detection
Program ⇒ Protection Parameters ⇒ Phase Loss
This parameter Enables/Disables the monitoring of each phase of the 3-phase
output signal (U, V, or W) of the AS D . If either line is missing, inactive, or not
of the specified level, the ASD incurs a trip.
Settings:
Disabled
Enabled (box checked)
Direct Access Number — F605
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
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. Lo wering the start f requency aides in m inimizing the
generated heat.
Direct Access Number — F606
Parameter Type — Numeri cal
Factory Default — 6.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 30.00
Units — Hz
Motor 150% OL Time Limit
Program ⇒ Protection Parameters ⇒ Overload
This parameter establishes a time that the mot or may operate at 150% of its
rated current before tripping. This settin g 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 overlo ad is greater
than 150%.
Direct Access Number — F607
Parameter Type — Numeri cal
Factory Default — 600
Changeable During Run — Yes
Minimum — 10
Maximum — 2400
Units — Seconds
Inrush Current Suppression
Program ⇒ Protection Parameters ⇒ Soft Star t
The startup inrush current may be suppressed for up to 2.5 seconds. This
parameter determines the length of the inr ush current suppressio n.
Direct Access Number — F608
Parameter Type — Numeri cal
Factory Default — 0.30
Changeable During Run — No
Minimum — 0.30
Maximum — 2.50
Units — Seconds
Interlock with ST
Program ⇒ Protection Parameters ⇒ Soft Star t
This parameter Enables/Disables the ST-to-CC connection dependency on the
successful completion of a Soft Start. If enabled, the ST-to-CC connection will
happen only after a successful Soft Start.
Direct Access Number — F609
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
