Description
V/f CL-V/f OLV CLV AOLV
Assigns a time filter to allow the torque limit to build at start.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the torque limit used during low-speed regeneration. Normally
there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the frequency width at which L7-35 [Derating Trq Lim For
Low Freq & Regeneration] operates.
Description
V/f CL-V/f OLV CLV AOLV
heatsink mounted braking resistor (ERF type, 3% ED).
0 : Not Provided
1 : Provided
V/f CL-V/f OLV CLV AOLV
Sets the oH detection level in temperature.
V/f CL-V/f OLV CLV AOLV
Sets the operation of drives when an oH alarm is detected.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast-Stop
3 : Alarm Only
4 : Run@L8-19 Rate
V/f CL-V/f OLV CLV AOLV
Enables or disables input phase loss detection.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Enables or disables the output phase loss detection. Output phase
loss detection is triggered when the output current falls below 5% of
the drive rated current.
Note:
Output phase loss detection can mistakenly be triggered in the
following situations. Disable output phase loss protection.
• The motor rated current is very small compared to the drive
rating.
• Operates PM motors with light loads.
0 : Disabled
1 : 1PH Loss Det
2 : 2/3PH Loss Det
V/f CL-V/f OLV CLV AOLV
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Selects the heatsink cooling fan operation.
0 : Dur Run (OffDly)
