Application Macros
Overview
Macros change a group of parameters to new, predefined values designed for
specific applications. Use macros to minimize the need for manual editing of
parameters. Selecting a macro sets all other parameters to their default values,
except:
• Group 99: Start-up Data parameters
• The
• The
• Groups 50...52 serial communication parameters
• Group 29: Maintenance triggers
After selecting a macro, additional parameter changes can be made manually using
the control panel.
Application macros are enabled by setting the value for parameter 9902
MACRO
General Considerations
The following considerations apply for all macros:
• When using a direct speed reference in AUTO mode, connect the speed
reference to analog input 1 (AI1), and provide the START command using digital
input 1 (DI1). In HAND/OFF mode, the control panel provides the speed
reference and START command.
• When using process PID, connect the feedback signal to analog input 2 (AI2). As
a default, the control panel sets the Setpoint, but analog input 1 can be used as
an alternate source. You can set up process PID using parameters (Group 40) or
using the PID control assistant (recommended).
