Vcomp Adjust 1
Sets voltage precision compensation. Usually it is not necessary to change this setting.

(0 - 200)
Note:
When there is audible noise during low-speed operation, set this parameter to 0.

Note:
When there is audible noise during high-speed operation, set this parameter to 0.
◆ C5: ASR - SPEED REGULATION
The ASR adjusts the output frequency or torque reference to decrease the difference between frequency reference
and motor speed. The control method sets the parameter that you must adjust.
Control Method Targets of Adjustment
Closed Loop V/f Control (CL-V/f) Output frequency
• Closed Loop Vector Control (CLV)
• Advanced Open Loop Vector Control (AOLV)
• Closed Loop Vector Control for PM (CLV/PM)
• PM Advanced Open Loop Vector (AOLV/PM)
• EZ Vector Control (EZOLV)
Torque Reference
Figure 12.47 Speed Control Block Diagram for Closed Loop V/f Control (CL-V/f)
Figure 12.48 Speed Control Block Diagram for CLV, AOLV, CLV/PM, AOLV/PM, and EZOLV
Note:
The detected speed is the speed estimation value when configured such that A1-02 = 4, 6, or 8 [Control Method = Adv OLVector, PM
AOLVector, or EZ Vector].
■ Before You Adjust ASR Parameters
• Do Auto-Tuning and set up all motor data correctly.
