Parameter ID Unit De‐
fault
Min Max Description
Cell voltage* 2550 Vrms 630 Set the value of the cell rated voltage:
• 460 V
• 630 V
• 690 V
• 450V (6SR5)
• 750 V (6SR4, 6SR5)
The cell types shown in the bullet list below appear in the
menus but are not applicable in this software version.
These cell types will be available in a later software ver‐
sion.
• 1375 V High Voltage
• 600 V AP AFE (PWM regen)
• 750 V AP
• 750 V AP 4Q (six-step regen)
• 1375 V High Voltage AP
Thermistor warn
level
2560 % 20.0 5.0 70.0 Set the level at which a cell over-temperature alarm is
generated.
Contactor settling
time
2570 msec 250.0 200 1000.0 Time taken by bypass contactors to change state.
Max back EMF de‐
cay time
2580 sec 7.0 0.0 10.0 Set the maximum time that the control waits for the mo‐
tor 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 will issue a fault.
Bypass type 2590 Mech Designate the type of bypass in the drive:
• Mechanical
• None
Fast bypass 2600 Disable Enables or disable fast cell bypass. Disabling fast bypass
with mechanical contactors will still provide manual by‐
pass after a manual reset.
AP Settings 2585 Submenu Access the AFE cell settings.
Display cell status 2610 Function Display cell status:
• A = active
• B = bypassed
• F = faulted
Format is all A phase followed by all B phase followed by
all C phase.
Display bypass sta‐
tus
2620 Function Display bypass status (same format as for cell status):
• A = available
• B = active
• U = unavailable
