FAULT
FUNCTIONS
(Continued)
TOTAL TRIALS TIME (31.15) Default: 30.0 s
Range: 1.0 - 600.0 s
Denes a time window for automatic fault resets. The maximum
number of attempts made during any period of this length is dened
by 31.14 Number of trials.
Note: If the fault condition remains and cannot be reset, each reset
attempt will generate an event and start a new time window. In
practice, if the specied number of resets (31.14) at specied
intervals (31.16) take longer than the value of 31.15, the drive
will continue to attempt resetting the fault until the cause is
eventually removed.
DELAY TIME (31.16) Default: 0.0 s
Range: 0.0 - 120.0 s
Denes the time that the drive will wait after a fault (or a previous reset
attempt) before attempting an automatic reset. See parameter 31.12
Autoreset selection.
SUPPLY PHASE LOSS (31.21) Default: 1 (Fault)
Range: 0, 1
0 (No action)
No action taken.
1 (Fault)
The drive trips on fault 3130 Input phase loss.
Selects how the drive reacts when a supply phase loss is detected.
BRAKE CHOPPER
Settings for the internal brake chopper.
BRAKING RESISTOR
TEMPERATURE (43.01)
Default: Read Only
Range: 0.0 - 120.0%
Displays the estimated temperature of the brake resistor, or how
close the brake resistor is to being too hot.The value is given in
percent where 100% is the temperature the resistor would reach if
the maximum continuous braking power (43.09 Brake resistor Pmax
cont) is applied to the resistor for 100% rated time. The thermal time
constant (43.08 Brake resistor thermal tc) denes the rated time to
achieve 63% temperature. 100% would be reached when 100% time
has elapsed.
BRAKE CHOPPER ENABLE
(43.06)
Default: 0 (Disabled)
Range: 0 - 2
0 (Disabled)
Brake chopper control disabled.
1 (Enabled with thermal model) Brake chopper enabled with resistor overload protection.
2 (Enabled without thermal
model)
Brake chopper control enabled without resistor overload protection. This
setting can be used, for example, if the resistor is equipped with a thermal
circuit breaker that is wired to stop the drive if the resistor overheats.
Enables brake chopper control.Note: Before enabling brake chopper
control, ensure that
• a brake resistor is connected
• overvoltage control is switched off (parameter 30.30 Overvoltage
control)
• the supply voltage range (parameter 95.01 Supply voltage) has been
selected correctly.
