9-36 MD65 AC Drive User Manual
Selects the drive action when an input signal loss is detected.
Signal loss is defined as an analog signal less than 1 V or 2 mA.
The signal loss event ends and normal operation resumes when the
input signal level is greater than or equal to 1.5 V or 3 mA. If using a
0-10 V analog input, set Anlg In 0-10V Lo (A110) to a minimum of
20% (i.e., 2 V).
1 = Fault (F29): F29 Analog Input Loss.
2 = Stop: Uses Stop Mode (P037).
3 = Zero Ref: Drive runs at zero speed reference.
4 = Min Freq Ref: Drive runs at minimum frequency.
5 = Max Freq Ref: Drive runs at maximum frequency.
6 = Int Freq Ref: Drive runs at internal frequency.
Enables/disables bipolar control. In bipolar mode, direction is
commanded by the sign of the reference.
Enables/disables a feature that varies the carrier frequency for the
PWM output waveform defined by PWM Frequency (A091).
Disabling this feature when low frequency conditions exist may
result in IGBT stress and nuisance tripping.
A123 10V Bipolar Enbl
Range: 0 = Uni-Polar In (0 to 10 V only)
1 = Bi-Polar In (+/-10 V)
Default: 0 = Uni-Polar In

A124 Var PWM Disable
Range: 0 = Enabled
1 = Disabled
Default: 0 = Enabled
