V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the time for mechanical deterioration detection.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time that the drive will start mechanical deterioration detection triggered by the cumulative
operation time of the drive.
V/f OLV OLV/PM AOLV/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 OLV/PM OLV/PM AOLV/PM EZOLV
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque is the
100% value.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the torque limit value for forward regenerative conditions as a percentage of the motor rated
torque.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the torque limit value for reversed regenerative conditions as a percentage of the motor rated
torque.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the integral time constant for the torque limit function.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the torque limit function during acceleration and deceleration.
0 : Proportional only
1 : Proportional & Integral control
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Assigns a time filter to allow the torque limit to build at start.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function to enable braking resistor protection with a Yaskawa ERF series braking resistor
(3% ED) installed on the heatsink.
0 : No
