Description
All Modes
Specifies the frequency reference reduction gain at overheat pre-alarm when
L8-03 = 4.
All Modes
Determines drive response when a fault occurs with the internal cooling fan.
0: Ramp to stop
1: Coast to stop
2: Fast stop (Decelerate to stop using the deceleration time set to C1-09)
3: Alarm only ("FAn" will flash)
4: Continue operation at reduced speed as set to L8-19.

Sets the time that the drive continues running with reduced carrier frequency
after the carrier reduction condition is gone. Setting 0.00 s disables the carrier
frequency reduction time.
All Modes
0: Disabled
1: Enabled. An alarm is triggered at output currents above 150% of drive rated
current.
All Modes
Detects the loss of an output phase in any of the inverter output modules.
0: Disabled
1: Enabled
All Modes
Detects the loss of the drive panel fan by the panel fan input.
0: Ramp Stop (Fault)
1: Coast Stop (Fault)
2: Fast Stop (Fault)
3: Continue Running (Alarm)
4: As for continue Running at L8–19 Speed
5: Disabled
Note: Settings 3 and 4 reduce inverter O/L level from 100% to 80 %.
All Modes
Detects the loss of the diode converter fan(s) by the fan control input.
0: Ramp Stop (Fault)
1: Coast Stop (Fault)
2: Fast Stop (Fault)
3: Continue Running (Alarm)
4: As for continue Running at L8–19 Speed
5: Disabled
Note: Settings 3 and 4 reduce inverter O/L level from 100% to 80 %.
