Emergency Off DC Injection Application Time
Program Protection Emergency Off
When DC Injection is used as a function of receiving an Emergency Off
command (
F603), this parameter determines the time that the DC Injection
braking is applied to the motor.
Direct Access Number — F604
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Ye s
Minimum — 0.00
Maximum — 10.00
Units — Seconds
Output Phase Loss 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
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
OL Reduction Starting 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 — Ye s
Minimum — 0.00
Maximum — 30.00
Units — Hz
Motor 150% OL Time Limit
Program Protection Overload
This parameter establishes a time that the motor may operate at 150% of its
rated current before tripping. This setting 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 overload is greater
than 150%.
Direct Access Number — F607
Parameter Type — Numerical
Factory Default — 600
Changeable During Run — Ye s
Minimum — 10
Maximum — 2400
Units — Seconds
Inrush Current Suppression
Program Protection Soft Start
The startup inrush current may be suppressed for up to 2.5 seconds. This
parameter determines the length of the inrush current suppression.
Direct Access Number — F608
Parameter Type — Numerical
Factory Default — 0.30
Changeable During Run — No
Minimum — 0.30
Maximum — 2.50
Units — Seconds
Interlock with ST
Program Protection Soft Start
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
