7-3 Description of Functions
F6008 Braking excitation time
The function to set the braking excitation time in vector control mode (speed sensor
and speed sensorless).
Correspond to DC braking time in V/f mode during startup (F1113).

Typical values have been entered for each motor model.
● Set the connecting time for excitation current set by F6007.
● When 0 is set, the braking function during startup will be disabled.
Note: The setting value is interlocked with the settings of motor poles, voltage and capacity (F5001). Therefore, when
F5001 is changed, F6008 will be automatically set to standard values according to F5001.
Reference parameter
F1001 (motor control mode selection)
F5001 (motor poles, voltage and capacity)
F6009 Current control gain compensation
This function is to compensate the setting values of current control gain during the speed control in the vector control
mode (speed sensor and speed sensorless). The function not only can be used to adjust speed control gain, but also can
be used when the motor vibration cannot be eliminated.

F6009 Current control gain compensation 0.5-1.5 0.01 1

The initial value of current control gain compensation (F6009) is 1. The gain will be controlled with the current
preset according to various motors.

The current control gain is adjustable according to the settings in current control gain compensation. The variable
range is 0.5-1.5 multiples.

During adjusting control gain and before using this function, please firstly make an adjustment with speed control
gain (F6010 & F6011). When the adjustment of speed control gain cannot improve the control performance, please
adjust this function.
Note 1: Optimum values have been set for current control gain according to different motors, the users cannot make a
direct change.
Note 2: When the limit value of current control gain compensation has been increased or decreased, the control
performance may become worse.
Reference parameter
F6010 (Speed control ASR proportional gain)
F6011 (Speed control ASR integral time)
F6010 Speed control ASR proportional gain
The function to set the proportional gain of speed control (ASR) in vector control mode (speed sensor and speed
sensorless).

Typical values have been entered for each motor model.
● Typical values applicable for the motor should be set for factory presets.
● As the target for adjustment, please set 100% for motor response 200rad/s.
Note 1: Besides this function code, the proportional gain of speed control will change according to the settings of motor
inertia moment (F5015) and load inertia moment ratio. Therefore, when adjusting the motor response by this
function, please set motor inertia moment to be equal to actual load.
Note 2: When using the function of motor vibration reduction rate (F6014), the speed control proportional gain will
automatically change according to the setting and load conditions.
