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.
 FOCPG(IM) control mode:
When drive is running at constant speed and torque current is lower than 35% of drive rated
current, drive will start to count. After 5 seconds, power save function will enable (can max. reduce
30% of output voltage). Return conditions: torque higher than 50% of drive rated current.
 VF, VFPG, SVC control mode:
When drive is running at constant speed and the U, V, W output power factor angle
cos(phi)>=65.0° (Pr00-04 set 5 for monitor power factor angle cos(phi)), drive will start to do
"Power saving enable time counting". After 5 seconds, power save function will enable.
Return conditions: (cos(phi)<60.0°) or drive is operating at acceleration or deceleration status.
