Variables
C_E6
%
Capacitance
The value in this variable selects the
capacitance connected to the bus. The value is
scaled in microfarads.
Units:
µF
Default Value:
32400
Low Limit:
32400
High Limit:
97200
Step:
1
For a single power unit, assign a value of 32400. For two parallel power units,
64800. For three parallel power units, 97200.
GIT_E1%
Ground Current Threshold
A drive warning is generated (register 203/
1203, bit 2) if the ground current in the rectifier
goes above the value stored in this variable.
The value is scaled in amps times 10; i.e., 100
represents 10.0 amps.
Units:
Amps * 10
Default Value:
100
Low Limit:
10
High Limit:
2000
Step:
1
This value should be set above the value in the ground current feedback register
(208/1208) after the drive is operational.
IST_E1%
Current Sharing Warning Threshold
A drive warning is generated (register 203/
1203, bit 6) if the
bus current is less than the value stored in this
tunable variable. The value is scaled in amps
times 10; i.e., 600 represents 60.0 amps.
Units:
Amps * 10
Default Value:
600
Low Limit:
10
High Limit:
2000
Step:
1
This variable should be left at the default value if the rectifier has only a single power
unit.
