Chapter 4 - Standard
Introduction
The standard application is typically used in basic motor control scenarios where multiple pump control, or advanced control
loops are not required. It provides the ability for the user to define its local and remote control and reference signals. In
addition, there is the ability to scale the analog input and output signals to be read based off the desired motor response.
There are two reserved digital inputs for start forward and reverse, also two digital inputs, and two relay outputs that can
be programmed to allow for control schemes that require the drive to have certain functions. It provides full customization
on the motor control sequence with the ability to be in frequency or speed control mode, and tuning of the V/Hz curve can
be selected. Drive/Motor protections can be customized to defined actions for added user control. Below is a list of other
features that are available in the standard application.
Standard Application includes functions:
• Selectable digital input function
• Selectable digital output function
• Reference filter, scaling, inversion, offset, and range
• Output signal filter, scaling, inversion, offset, and range
• Selectable analog output function
• S curves
• Start source (Local/remote control function)
• Reference source
• Flying start
• Volts per Hertz control
• Programmable switching frequency
• Multi-preset speeds
• Emergency stop

“Function to terminal” (FTT) programming
The design behind programming of the digital inputs and outs of the DM1 uses “function to terminal” programming. It is
composed of a terminal, be it a relay output or a digital output, that is assigned a parameter. Within that parameter, it has
different functions that can be set.
