Description
V/f OLV/PM EZOLV OLV/PM
Sets the detection time for Overtorque/Undertorque Detection 2.
V/f OLV/PM EZOLV OLV/PM
Sets the motor underload protection (UL6 [Undertorque Detection 6]) based on motor load
and sets the level of L6-02 [Torque Detection Level 1] to refer to Fbase or Fmax.
0 : Base Frequency Enable
1 : Max Frequency Enable
V/f OLV/PM EZOLV OLV/PM
Sets the UL6 [Undertorque Detection 6] detection level at minimum frequency by
percentage of drive rated current.
Description
V/f OLV/PM EZOLV OLV/PM
Sets the torque limit value for forward motoring as a percentage, where motor rated torque
is the 100% value.
V/f OLV/PM OLV/PM EZOLV
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque
is the 100% value.
V/f OLV/PM EZOLV OLV/PM
Sets the torque limit value for forward regenerative conditions as a percentage of the motor
rated torque.
V/f OLV/PM EZOLV OLV/PM
Sets the torque limit value for reversed regenerative conditions as a percentage of the
motor rated torque.
V/f OLV/PM EZOLV OLV/PM
Assigns a time filter to allow the torque limit to build at start.
0 : Disabled
1 : Enabled
Description
V/f OLV/PM EZOLV OLV/PM
Sets the oH detection level temperature.
V/f OLV/PM OLV/PM EZOLV
Sets drive operation if it detects an oH alarm.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
4 : Operate at Reduced Speed (L8-19)
V/f OLV/PM EZOLV OLV/PM
Sets the function to enable and disable input phase loss detection.
0 : Disable
1 : Enabled
V/f OLV/PM OLV/PM EZOLV
Sets the function to enable and disable output phase loss detection. The drive starts output
phase loss detection when the output current decreases to less than 5% of the drive rated
current.
Note:
The drive can incorrectly start output phase loss detection in these conditions:
• The motor rated current is very small compared to the drive rating.
• The drive is operating a PM motor with a small load.
0 : Disabled
1 : Fault when one phase is lost
2 : Fault when two phases are lost
