 Automatic voltage regulator function provides a level of output voltage stability when there is
input voltage instability. So when 08-08=0, Input voltage fluctuations will not effect the output
voltage.
 08-08=1. Input voltage fluctuations will cause fluctuations on output voltage.
 08-08=2. AVR is disabled during stopping to avoid an increase in stopping time.
 08-08=3. AVR is disabled only during deceleration from one speed to another speed. This will
avoid longer than required deceleration time.
 08-08=4, AVR function disabled for stop & Deceleration from one speed to another speed.
 08-08=5, When VDC>360(200V series) or VDC>740V(400V series), AVR function is disabled
for stop and deceleration.

 Selection for motor overheat protection:
PTC (Positive temperature coefficient) sensors are used in motor windings to provide additional
motor protection from overheat.
PTC thermistor can be connected to terminals AVI and AGND.
A voltage divider resistor R is necessary to be connected as shown below in figure (b).
1) PTC Over Temperature Detection: If 08-10 =1 (Decelerate to stop) or 2 ( Cost to stop).
Over temperature is detected by PTC input at terminal AVI.
