Chapter 1 Detail Drive Configuration and Operation
Application Example:
Parameter 376 [Inv Ol Pend Cnfg] is set to a value of 1 “Alarm”. This configures
the drive to set the alarm bit, parameter 326 [Alarm Status 1] bit 15 “Inv OL
Pend” when the inverter overload pending event occurs. This alarm will allow the
drive to continue running. The user can make the decision as to what action to
take in relation to the alarm.
Analog Inputs Analog Input Specifications
There are 2 analog inputs located on TB1 - Row B (Bottom Terminals). Each
input accepts a +/-10V or +/-1V bipolar, differential signal. Dip switches SW1-1
and SW1-2 are used to select whether the analog inputs are +/-10V or +/-1V.
The A/D converter is 14 bits including the sign bit (13 bits plus the sign bit).
Analog Input Configuration
Once the Analog Input is converted, [Anlg Inx Offset] can be applied. This
parameter has a range of +/-20V. [Anlg Inx Volts] is the sum of the A/D output
and [Anlg Inx Offset]. [Anlg Inx Volts] are displayed as +/-10V.
[Anlg Inx Scale] scales [Anlg Inx Volts] to the range of [Anlg Inx Data]. A
destination parameter, such as a speed reference can then be linked to [Anlg Inx
Data].
[AIx Filt Gain] and [Anlg Inx Filt BW] are used to filter the analog input data.
