1.3 C: Tuning
n C3-05: Output Voltage Limit Operation Selection
Determines if the motor flux reference is automatically reduced when output voltage reaches the saturation range.
If the input power supply voltage is low or the motor has a high voltage rating, this function improves the speed precision
when moving heavy loads at high speeds. When selecting the drive, remember that the reduction in flux causes a slightly
higher current at high speed when this function is enabled.
No.
C3-05
Note: Available control modes for parameter C3-05 vary by drive model:
Models 2A0004 to 2A0415, 4A0002 to 4A0675, and 5A0003 to 5A0242: Available when A1-02 = 2, 3
Models 4A0930 and 4A1200: Available when A1-02 = 2, 3, 6, 7
A1000 HHP: Available when A1-02 = 2 or 3
Setting 0: Disabled
Setting 1: Enabled
n C3-16: Output Voltage Limit Operation Start Level (Percentage Modulation)
Sets the output voltage limit operation start level (percentage modulation) when C3-05 is enabled.
Note: This parameter is only available in models 4A0930, 4A1200, and A1000 HHP.
No.
C3-16
n C3-17: Maximum Output Voltage Limit Level (Percentage Modulation)
Sets the output voltage limit operation determined by C3-18 (percentage modulation) when C3-05 is enabled.
Note: This parameter is only available in models 4A0930, 4A1200, and A1000 HHP.
No.
C3-17
n C3-18: Output Voltage Limit Level
Sets the maximum percentage of output voltage reduction when C3-05 is enabled.
Note: This parameter is only available in models 4A0930, 4A1200, and A1000 HHP.
No.
C3-18
n C3-21: Motor 2 Slip Compensation Gain
Improves the speed accuracy for motor 2 and functions in the same way that C3-01 functions for motor 1. Adjust this parameter
only after setting the motor rated current (E4-01), motor rated slip (E4-02), and the motor no-load current (E4-03).
Refer to C3-01: Slip Compensation Gain on page 48
No.
C3-21 Motor 2 Slip Compensation Gain
Note: Default setting is 0.0 in V/f Control (E3-01 = 0). Default setting is 1.0 in Open Loop Vector Control (E3-01 = 2) and Closed Loop Vector
Control (E3-01 = 3). In Closed Loop Vector Control, slip compensation gain acts as an adaptable gain.
n C3-22: Motor 2 Slip Compensation Primary Delay Time
Functions for motor 2 the same way that C3-02 functions for motor 1.
Refer to C3-02: Slip Compensation Primary Delay Time on page 49
No.
C3-22 Motor 2 Slip Compensation Primary Delay Time
Note: The default for V/f Control (E3-01 = 0) is 2000 ms. The default for Open Loop Vector Control (E3-01 = 2) is 200 ms.
