Description
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for the slip compensation function as a percentage of the motor 2
rated slip.
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation during regenerative operation function for motor 2.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above C3-15
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation function mode.
0 : Normal
1 : Advanced
Description
V/f CL-V/f OLV CLV AOLV
Sets the gain for the torque compensation function. Use this parameter value for motor
1 when operating multiple motors.
V/f CL-V/f OLV CLV AOLV
Sets the torque compensation delay time. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the value if ov [Overvoltage] occurs with sudden changes in the load, at the end of
acceleration, or at the start of deceleration.
V/f CL-V/f OLV CLV AOLV
Sets the gain for motor 2 torque compensation function when using the Motor Switch
function.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time for motor 2 torque compensation.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for torque compensation when the drive receives a
Reverse run command and b1-23 = 1 [Selection REV Parameters = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for torque compensation for motor 2 when the
drive receives a Reverse run command and b1-23 = 1 [Selection REV Parameters =
Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for torque compensation that the drive uses when
b1-23 = 0 [Selection REV Parameters = Disabled] or b1-23 = 1 [Enabled], and the
MFDI "Counterweight Selection" setting is ON for the Forward run command.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for torque compensation that the drive uses when
the reverse command activates, b1-23 = 1 [Selection REV Parameters = Enabled], and
the MFDI "Counterweight Selection" setting activates.
V/f CL-V/f OLV CLV AOLV
If there is slow oscillation at low speeds, adjust this setting. Usually it is not necessary
to change this setting.
Increase this parameter in 1.0 Hz increments when current ripples and torque ripples
occur during low-speed operation. Set this parameter to 0.0 to disable the function if
increasing the value does not fix the problem.
V/f CL-V/f OLV CLV AOLV
Sets voltage precision compensation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets voltage precision compensation. Usually it is not necessary to change this
parameter.
V/f CL-V/f OLV CLV AOLV
Sets the Current control gain. Usually it is not necessary to change this parameter.
