Description
Sets the drive operation when an overheat alarm oH is
detected.
0: Ramp to Stop using the active decel time.
1: Coast to Stop.
2: Fast-stop using the time set in C1-09.
3: Alarm Only. Drive continues running, but displays an alarm.
4: Reduced Speed Operation. Drive continues to run with
reduced frequency reference as specified in L8-19.
Settings 0 through 2 trigger a fault relay if the heatsink
becomes too hot.
Selects the detection of input current phase loss, power supply
voltage imbalance, or main circuit electrolytic capacitor
deterioration.
0: Disabled
1: Enabled
Note: This parameter is disabled in 200 V single-phase drives.
Selects the output phase loss detection.
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
Output phase loss is detected when operating with less than
5% of the drive rated current. Detection can mistakenly occur
if the motor is small relative to the drive capacity rating (this
parameter should be disabled in such cases).
Selects the output ground fault detection.
0: Disabled
1: Enabled
Controls the heatsink cooling fan operation.
0: Run with timer (Fan operates only during run and for L8-11
seconds after stop.)
1: Run always (Cooling fan operates whenever the drive is
powered up.)
This parameter sets the delay time for the cooling fan to shut
off after the run command is removed when L8-10 = 0.
drives oL2 detection level.
Sets the oL2 characteristics at output frequencies below 6 Hz.
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0
Hz.
Selects the software current limit function. Typically no
adjustment is required.
0: Disabled
1: Enabled
Specifies the frequency reference reduction gain at overheat
pre-alarm when L8-03 = 4.
Selects the detection of unbalanced output currents caused by
faulty devices in the output circuit.
0: Disabled
1: Enabled
Selects the installation type:
0: IP20/Open-Chassis Drive, IP00/Open-Chassis Drive
1: Side-by-Side Mounting
2: NEMA Type 1 Drive
3: Finless Drive or External Heatsink Installation
Provides protection to the IGBTs by reducing the carrier
frequency at low speeds.
0: Disabled
1: Enabled below 6 Hz
2: Enabled for the whole speed range
