V/f CL-V/f OLV CLV AOLV
Sets the time for mechanical deterioration detection.
V/f CL-V/f OLV CLV AOLV
Sets the time that the drive will start mechanical deterioration detection triggered by the
cumulative operation time of the drive.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for forward motoring as a percentage, where motor rated torque
is the 100% value.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque
is the 100% value.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for forward regenerative conditions as a percentage of the motor
rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for reversed regenerative conditions as a percentage of the
motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the integral time constant for the torque limit function.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit function during acceleration and deceleration.
0 : Proportional only
1 : Proportional & Integral control
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. Usually it is not necessary to
change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the frequency width at which L7-35 [Low Freq Regen Torque Limit Lvl] operates.
V/f CL-V/f OLV CLV AOLV
Sets the function to enable braking resistor protection with a Yaskawa ERF series braking
resistor (3% ED) installed on the heatsink.
0 : Disabled
1 : Enabled
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 (Use C1-09)
3 : Alarm Only
4 : Operate at Reduced Speed (L8-19)
