Chapter 12 Description of Parameter Settings
Emergency Stop (EF) & Force Stop
Settings
When the multi-function input terminal is set to 10(EF) or 18(Emergency stop) and is activated,
the drive will stop according to the setting in Pr.07-20.
Auto Energy-saving Operation
Settings
When Pr.07-21 is set to 1, the acceleration and deceleration will operate with full voltage. During
constant speed operation, it will auto calculate the best voltage value by the load power for the
load. This function is not suitable for the ever-changing load or near full-load during operation.
When the output frequency is constant, i.e. constant operation, the output voltage will auto
decrease by the load reduction. Therefore, the drive will operate with min. power, multiplication
of voltage and current.
Energy-saving Gain
Settings
When Pr. 07-21 is set to 1, this parameter can be used to adjust the gain of energy-saving. The
factory setting is 100%. If the result is not good, it can adjust by decreasing the setting. If the
motor oscillates, it should increase the setting value.
At some special application such as High speed spindle, the motor temperature rise is been
highly concern. Thus, when the motor is not working with load, the motor current will requested
to reduce to a lower level. To Lowering this parameter setting can meet this requirement.
Auto Voltage Regulation(AVR) Function
Settings
The rated voltage of the motor is usually 220V/200VAC 60Hz/50Hz and the input voltage of the
AC motor drive may vary between 180V to 264 VAC 50Hz/60Hz. Therefore, when the AC motor
drive is used without AVR function, the output voltage will be the same as the input voltage.
When the motor runs at voltages exceeding the rated voltage with 12% - 20%, its lifetime will be
shorter and it can be damaged due to higher temperature, failing insulation and unstable torque
output.
