Cell voltage
2550
Vrms
630
Sets the value of the cell rated
voltage:
•
460V

690V
Thermistor warn level

Sets the level at which a temperature
alarm is generated.
Contactor settling time
2570
msec
250.0
0.0
1000.0
Time taken by bypass contactors to
change state. Use 100ms for small
contactors and 250ms for larger
ones.
Max back EMF decay
time
2580
sec
7.0
0.0
10.0
Sets the maximum time that the
control waits for the motor voltage
to decay while attempting a fast
bypass.
Once cell fault(s) occurs, the drive
may not be able to support actual
motor voltage. If the motor voltage
does not decay below the max drive
voltage capability (with the faulted
cell(s)) within the time set by this
parameter, the drive issues a fault.
Bypass Type
2590
Mech
Designates the type of bypass in the
drive:
•
Mechanical
•
None
Fast bypass
2600
Disable
This parameter enables or disables
fast cell bypass. Disabling fast
bypass with mechanical contactors
will still provide manual bypass after
a manual reset.
Display Cell Status
2610
Function
Displays cell status:
•
A = active,
•
B = bypassed,
•
F = faulted.
