Programming Parameters
5–45
Absolute Overspeed Threshold
[Absolute Overspd]
Parameter Number
90
Parameter Type
Sink
Display Units
x.x rpm
Drive Units
4096 = 100.0% overspeed
Factory Default
0.1 x base speed
Minimum Value
0.0 rpm
Maximum Value
base speed
This parameter indicates the incremental
speed above Forward Speed Limit or be-
low Reverse Speed Limit that is allowable
before an Absolute Overspeed Fault is
indicated.
Stall Delay
[Stall Delay]
Parameter Number
91
Parameter Type
Sink
Display Units
x.x sec.
Drive Units
sec. x 10.0
Factory Default
1.0 sec
Minimum Value
0.1 sec
Maximum Value
3276.7 sec
This parameter specifies the amount of
time that the Drive must be in current limit
and at zero speed before a Stall Fault will
be indicated.
Motor Overload Limit
[Mtr Overload Lim]
Parameter Number
92
Parameter Type
Sink
Display Units
xx.x%
Drive Units
4096 = 100% Iq for 60 sec.
Factory Default
200.0%
Minimum Value
110.0%
Maximum Value
400.0%
This parameter specifies the level of Iq
current that will cause a Motor Overload
Trip after 60 seconds.
Service Factor
[Service Factor]
Parameter Number
94
Parameter Type
Sink
Display Units
x.xx
Drive Units
4096 = 1.00
Factory Default
1.00
Minimum Value
1.00
Maximum Value
2.00
This parameter specifies the minimum lev-
el of Iq current that will cause a motor over-
load (IIT) trip under continuous operation.
Current levels below this value will never
result in an overload trip.
Example – a service factor of 1.15 implies
continuous operation up to 115% of name-
plate motor current.
Overload Speed 1
[Mtr Overld Spd 1]
Parameter Number
95
Parameter Type
Sink
Display Units
+/– x.x rpm
Drive Units
4096 = Base Motor Speed
Factory Default
0.8 x Base Speed
Minimum Value
0.0 rpm
Maximum Value
2 x Base Speed
If the absolute value of motor speed is at or
below the speed specified in this parame-
ter, the motor overload will use the Min
Overload Lmt (parameter #97) as its mini-
mum current trip level.
Motor Overload Speed 2
[Mtr Overld Spd 2]
Parameter Number
96
Parameter Type
Sink
Display Units
+/– x.x rpm
Drive Units
4096 = Base Motor Speed
Factory Default
0.8 x Base Speed
Minimum Value
0.0 rpm
Maximum Value
2 x Base Speed
If the absolute value of motor speed is at or
below the speed specified in this parame-
ter, the motor overload will use 100% as its
minimum current trip level.
Minimum Overload Limit
[Min Overload Lmt]
Parameter Number
97
Parameter Type
Sink
Display Units
x.x%
Drive Units
4096 = 100.0% current
Factory Default
100.0%
Minimum Value
0.0 %
Maximum Value
100.0%
This is the minimum motor overload trip
level that will be in effect when the motor
speed is at or below Mtr Overld Spd 2
