9.4.2 Macro Groups (MC1, MC2, MC3)
The Macro selection function pulls together various parameters into one group that are common to specific
applications and load type. The H2 Series inverter includes 3 macros (Pump, Fan and Constant Torque).
Groups MC1, MC2, or MC3 are displayed in the U&M Mode when the user selects the macro with
parameter CNF-43. Parameters within each macro can be modified. Macro groups cannot be added by the
user.
Accessing Macro Group - When a macro is selected at CNF-43 or during the Quick Start menu, press the
Mode button to move to the U&M Mode that will now be displayed along with the MCx group of parameters.
This MCx group will show all parameters in the specific macro group. The default settings within the MCx
group are shown in the following tables and can be modified.
The parameters within each macro are tied to the same parameters in the various parameter groups.
Changes made to macro group parameters are reflected in the other groups. Selecting '0 (Basic)' initializes
all parameter changes to default settings.
9.4.2.1 MC1 - Pump Macro
The Pump Macro includes typical pump related parameter settings. Some of these are a ‘Squared’ V/Hz
pattern for variable torque loads along with “S-Curve” acceleration and deceleration. A minimum frequency
of 30 Hz. is set along with reverse run prevention. The PID group parameters are included but are not
enabled. If enabled with MC1-43 (PID-01), the default control is normal PID and units are in PSI. The
shaded settings are different from the standard inverter parameter settings.
