LIMIT CONFIG
Current
100 [Active I Lmt]
Sets the current limit used when the IGBT overload is less than 90% of the IT
fault threshold.
Default:
Min/Max:
Units:
Rated * 1.5 Amps
Rated ÷ 4/Rated*1.5 Amps
0.1 Amps
101 [Active OL I Lmt]
Sets the current limit used when the IGBT overload is more than 90% of the IT
fault threshold, and parameter 150 - [Reduce Ilmt Sel] is set to “1” (enabled).
Default:
Min/Max:
Units:
Rated * 0.9 Amps
Rated ÷ 4/Rated*1.5 Amps
0.1 Amps
102 [Reactive RateLmt]
Sets how fast reactive current will change.
Default:
Min/Max:
Units:
100.0 A/sec
10.0/3000.0 A/sec
0.1 A/sec
103 [I Imbalance Lmt]
Sets the limit on phase current imbalance. A fault is generated if the calculated
imbalance is greater than this limit for the time defined in parameter 104 -
[I Imbalance Time].
Default:
Min/Max:
Units:
30.0%
1.0/90.0%
0.1%
104 [I Imbalance Time]
Sets the time delay in faulting on current imbalance between phases. A fault is
generated if the calculated imbalance is greater than the limit set by parameter
103 - [I Imbalance Lmt] for this amount of time.
Default:
Min/Max:
Units:
10.0 Sec
1.0/10.0 Sec
0.1 Sec
105 [Regen I Lmt]
Sets the maximum phase current the unit will request when regenerating. Values
are entered as a percent of converter rated current. When the converter goes
into current limit while regenerating, the DC link will go up and the unit may fault
on DC Over Voltage if the condition is not externally corrected.
Default:
Min/Max:
Units:
-150.0%

110 [Ride Through Ena]
Selects the options for power dip ride through.
“Disabled” = The Converter will fault on loss of AC line voltage and will not
automatically attempt to restart when power returns.
“Enabled” = The Converter will enter Standby Mode, and wait for the AC line
voltage to return, and then automatically resume operation. If power is not
restored within the time defined in parameter 111 - [Ride Through Sec], a fault is
generated.
Default:

111 [Ride Through Sec]
Selects the longest power dip that will be allowed providing DC link voltage can
be maintained.
Default:
Min/Max:
Units:
10.0 Sec
0.1/600.0 Sec
0.1 Sec
112 [Low Vac Lmt]
Sets the low limit on AC Line voltage. A fault or alarm may be generated when
the AC Line voltage is less than this limit for the time set by parameter 113 - [Low
Vac Time].
Default:
Min/Max:
Units:
340.0 Vac
200.0/800.0 Vac
0.1 Vac
113 [Low Vac Time]
Sets the time delay in detecting low AC Line voltage. A fault or alarm may be
generated when the AC Line voltage is less than the limit set by parameter 112 -
[Low Vac Lmt] for this amount of time.
Default:
Min/Max:
Units:
5.0 Sec
0.1/30.0 Sec
0.1 Sec
114 [High Vac Lmt]
Sets the high limit on AC Line voltage. A fault or alarm may be generated when
the AC Line voltage is greater than this limit for the time set by parameter 115 -
[High Vac Time].
Default:
Min/Max:
Units:
Rated*1.1 Vac
400.0/810.0 Vac
0.1 Vac
115 [High Vac Time]
Sets the time delay in detecting high AC Line voltage. A fault or alarm may be
generated when the AC Line voltage is greater than the limit set by parameter
114 - [High Vac Lmt] for this amount of time.
Default:
Min/Max:
Units:
5.0 Sec
0.1/30.0 Sec
0.1 Sec
116 [V Imbalance Lmt]
Sets the limit on voltage imbalance between phases. A fault or alarm may be
generated if the calculated imbalance is greater than this limit for the time set by
parameter 117 - [V Imbalance Time].
Default:
Min/Max:
Units:
10.0%
1.0/20.0%
