• When a shock is generated at startup, increase the setting for the starting-torque compensation time
constant (C4-05). Use either the DC injection braking at startup (b2-03) or the “DC braking reference”
multi-function input (set value: 60) to raise the motor ’ s magnetic flux in advance before startup. (The
magnetic flux from the DC injection braking at startup (b2-03) can also be brought up quickly . Refer to
Setting DC Injection Braking (b2) on page 6-42 for details.)
6-1-7 Selecting Auto-tuning Carrier Frequency
The auto-tuning carrier frequency is by default set to a value higher than that used for conventional
models to improve the accuracy of auto-tuning. The default setting does not normally need to be
changed.

Setting Description
0 The auto-tuning carrier frequency is set to 2 kHz.
1 The auto-tuning carrier frequency is set according to the set value of parameter C6-01.
2 The auto-tuning carrier frequency is set to 5 kHz.
Note The default setting does not normally need to be changed. Adjust the parameter with the parame -
ter C6-01 set to 0 or 1 if auto tuning cannot be executed.
6-1-8 Setting/Adjusting Motor Parameters
H Adjusting the V/f Pattern
Normally it isn’t necessary to adjust the V/f pattern with open-loop vector control. Adjust the V/f pattern
when you want to change the maximum frequency setting or decrease the Inverter ’ s output voltage or
when stalls are occurring during no-load operation. It is possible to make user-defined V/f pattern set -
tings
(E1-04 through E1-10) in open-loop vector control mode. (The preset V/f patterns cannot be se -
lected.)
