Description
V/f CL-V/f OLV CLV AOLV
Adjusts the slip compensation delay time for motor 2 when speed is
unstable or when the slip compensation response is too slow.
Normally there is no need to change this setting.
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
Enables or disables slip compensation for motor 2 during
regenerative operation.
0 : Disabled
1 : Enabled (6 Hz and above)
2 : Enabled (compensation provided wherever possible)
V/f CL-V/f OLV CLV AOLV
0 : Normal
1 : Advance
Description
V/f CL-V/f OLV CLV AOLV
Sets the gain for the torque compensation function. Sets the gain for
motor 1 when multiple motors are driven.
V/f CL-V/f OLV CLV AOLV
Sets the torque compensation delay time in milliseconds. Normally
there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the amount of torque reference at start in the forward direction
as a percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the amount of torque reference at start in the reverse direction
as a percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the starting torque constant used with C4-03 and C4-04
[Torque Compensation @ REV Start].
V/f CL-V/f OLV CLV AOLV
load, at the end of acceleration, or at the start of deceleration.
V/f CL-V/f OLV CLV AOLV
Sets the motor 2 gain for the torque compensation function when
using the Motor Switch function.
V/f CL-V/f OLV CLV AOLV
Increase the setting in increments of approximately 1.0 when current
ripples and torque ripples occur during low-speed operation. If this
still does not improve the situation, set C4-19 = 0 to disable this
function. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
This parameter compensates the voltage accuracy. Normally there is
no need to change this setting.
V/f CL-V/f OLV CLV AOLV
This parameter compensates the voltage accuracy. Normally there is
no need to change this setting.
