A122 [Analog In Loss]

Related Parameter(s):

A110

,

A111

,

A132

Selects drive action when an input signal loss is detected. Signal loss is defined as an analog signal
less than 1V or 2mA. The signal loss event ends and normal operation resumes when the input signal
level is greater than or equal to 1.5V or 3mA. If using a 0-10V analog input, set

A110

[Anlg In 0-10V

Lo] to a minimum of 20% (i.e. 2 volts).

Options

0 “Disabled” (Default)

1 “Fault (F29)”

F29 Analog Input Loss

2 “Stop”

Uses P037 [Stop Mode]

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.

A123 [10V Bipolar Enbl]

Related Parameter(s):

P038

,

A111

Enables/disables bipolar control. In bipolar mode direction is commanded by the sign of the reference.

Options

0 “Uni-Polar In” (Default) 0 to 10V only

1 “Bi-Polar In”

±10V

A124 [Var PWM Disable]

Related Parameter(s):

A091

Stop drive before changing this parameter.

Enables/disables a feature that varies the carrier frequency for the PWM output waveform defined by
A091 [PWM Frequency].
Disabling this feature when low frequency conditions exist may result in IGBT stress and nuisance
tripping.

Options

0 “Enabled” (Default)

1 “Disabled”

A125 [Torque Perf Mode]

Related Parameter(s):

A084

,

A085

,

A086

,

A087

,

A127

Stop drive before changing this parameter.

Enables/disables sensorless vector control operation.

Options

0 “V/Hz”

1 “Sensrls Vect” (Default)

A126 [Motor NP FLA]

Related Parameter(s):

A127

Set to the motor nameplate rated full load amps.
