P4.09 Analog Frequency Command for Reverse Run
♦R/W 0409 41034
Range/Units (Format: 16-bit binary) Default
0: Negative Frequency Input is Disabled�
Forward and reverse motions are controlled by digital keypad or by external
terminal�
1: Negative Frequency Input is Enabled�
Forward motion when positive frequency; reverse motion when negative frequency�
Forward and reverse motions are NOT controlled by digital keypad or by external
terminal�
Use this setting with AI3 (which can be up to ±10V), or with bias settings to achieve
positive and negative frequency commands�
Negative analog signals can be generated by AI3 (which has ability for ±10V signal),
or by any of the analog inputs used with bias� (A bias of -50% used with a 0~10V
signal will result in 0~5V = reverse rotation, and 5~10V = forward rotation)
0
NOTE: Fwd/Rev Direction Inhibit P6.09 can also eliminate reverse (or forward) motor direction.
NOTE: Refer to the detailed Analog Input Example #4 (page 4–116) at the end of these “Group P4.xx
