C5-07: ASR Gain Switching Frequency
■
Sets the frequency where the drive should switch between ASR proportional gain 1 and 2 (C5-01, C5-03) as well as
between integral time 1 and 2 (C5-02, C5-04).
No.
C5-07
Note: A multi-function input set for the ASR gain switch (H1-
Switching the proportional gain and integral time in the low or high speed range can help stabilize operation and avoid
resonance problems. A good switching point is about 80% of the frequency where oscillation occurs, or at 80% of the
target speed. Refer to C5-01, C5-03 / C5-02, C5-04: ASR Proportional Gain 1, 2 / ASR Integral Time 1, 2 on page
C5-08: ASR Integral Limit
■
Sets the upper limit for ASR as a percentage of the rated load.
No.
C5-08
C5-12: Integral Operation during Accel/Decel (V/f w/PG)
■
Enables integral operation during acceleration and deceleration. Integral operation should be used when driving a heavy
load or a high inertia load, but can cause problems with overshoot at the end of acceleration and deceleration. Refer to
ASR Setup Problems and Corrective Actions on page 173
No.
C5-12
Setting 0: Disabled
Integral operation occurs only during constant speed and not during acceleration or deceleration.
Setting 1: Enabled
Integral operation is always enabled.
C5-17, C5-18: Motor Inertia, Load Inertia Ratio
■
C5-17 and C5-18 determine the ratio of the machine inertia and the inertia of the motor being used.
These parameters are set automatically when Inertia Tuning and ASR Tuning are performed in CLV and CLV/PM control
modes. Refer to Auto-Tuning on page 109

C5-21, C5-23 / C5-22, C5-24: Motor 2 ASR Proportional Gain 1, 2 / Integral Time 1, 2
■
These parameters function for motor 2 in the same way that C5-01 through C5-04 function for motor 1. For more details,
see C5-01, C5-03 / C5-02, C5-04: ASR Proportional Gain 1, 2 / ASR Integral Time 1, 2 on page
