1077
Backspin Inhibit Time
UINT16 RW NV
Default: 0
Range: 0 to 3600
Units: seconds
Config CRC
Admin Lock
USB Lock
Backup Mem
Anti-backspin inhibit time before a reset is allowed.
1078
Run Transition Delay
UINT16 RW NV
Default: 10
Range: 2 to 360
Units: seconds
Config CRC
Run Lock
Admin Lock
USB Lock
Backup Mem
If the motor is instructed to run by the user, but the current thresholds are
not reached, the C445 will not fault on Undercurrent if that protection is
enabled because it has not realized a run state. If the user wants the unit
to fault under these conditions on an enabled protection following the
selected debounce time for that protection, a time must be selected for
this parameter.
1079
Alarm Delay
UINT16 RW NV
Default: 2000
Range: 200 to 5000
Units: ms
Config CRC
Admin Lock
USB Lock
Backup Mem
Alarm Delay Time - applies to all protection function alarms that are
enabled. This delay time is to avoid nuisance alarms. The fault condition
must be present longer than this time setting.
1080
Inhibit Start on Voltage
Fault
BOOL RW NV
Default: 0
Config CRC
Run Lock
Admin Lock
USB Lock
Backup Mem
If this parameter is enabled and a voltage supply problem exists when the
start command is issued, the C445 will be inhibited from starting the
motor. This applies to Over Voltage, Under Voltage and Voltage
Imbalance.
1081
Inhibit Start on Voltage
Fault - Undervoltage Level
UINT8 RW NV
Default: 90
Range: 10 to 100
Config CRC
Admin Lock
USB Lock
Backup Mem
If Inhibit Start on Voltage Fault is enabled, this Under Voltage threshold
value is used to inhibit the motor from being started.
1082
Inhibit Start on Voltage
Fault - Unbalance Level
UINT8 RW NV
Default: 6
Range: 1 to 20
Units: %
Config CRC
Admin Lock
USB Lock
Backup Mem
If Inhibit Start on Voltage Fault is enabled, this Voltage Unbalance
threshold value is used to inhibit the motor from being started.
1083
Inhibit Start on Voltage
Fault - Overvoltage Level
UINT8 RW NV
Default: 110
Range: 90 to 150
Units: %
Config CRC
Admin Lock
USB Lock
Backup Mem
If Inhibit Start on Voltage Fault is enabled, this Over Voltage threshold
value is used to inhibit the motor from being started.
