Analog Frequency Command for Reverse Run


Settings
 Parameter 03-10 is used to enable reverse run command when a negative frequency (negative
bias and gain) is input to AVI or ACI analog signal input.
 Analog Input Gain (AVI)
 Analog Input Gain (ACI)
Analog Positive Input Gain (AUI)

 Analog Negative Input Gain (AUI)
Settings
 Parameters 03-03 to 03-14 are used when the source of frequency command is the analog
voltage/current signal.
 Analog Input Filter Time (AVI)
 Analog Input Filter Time (ACI)
Analog Input Filter Time (AUI)

Settings
 These input delays can be used to filter noisy analog signal.
 When the setting of the time constant is too large, the control will be stable but the control response
will be slow. When the setting of time constant is too small, the control response will be faster but
the control may be unstable. To find the optimal setting, please adjust the setting according to the
control stable or response status.

0: Negative frequency is not valid. Forward and reverse run is controlled by digital
keypad or external terminal.
1: Negative frequency is valid. Positive frequency = forward run; negative frequency =
reverse run. Run direction can not be switched by digital keypad or the external
terminal control.
