Macro 2 Group (MC2)
This table lists parameters in the macro group (MC2). It includes the MC2 group parameter number cross referenced
to the original drive parameter along with default settings for Lead/Lag operation. The Notes provide a brief
description of the parameter settings. For detailed descriptions of the parameters, refer to
Group 1, AP1 Parameter Descriptions.
NOTE: For Lag drives only. Parameter MC2-03.
If using a single transducer to the Lead (+) drive only, set Lag drives to Network Feedback. If all drives are receiving
the transducer feedback signal, set Lag drives to same as the Lead (+) drive (Follow Lead or Fixed Lag).
