Do not access Inverter parameters while the Inverter is being re-initialized
(Refer to the MX2-A@ Inverter manual section 6-3). Accessing parameters
during a re-initialization will cause the Inverter to go into an undefined state.
3G3AX-MX2-PRT-E Option Board provides Parameter Access in accordance
with the PROFIdrive V4 profile definition. Access is only supported on DP-V1
Class 2 slot 0, index 47. You will therefore have to ensure that all
MSAC2_Initialize, MSAC2_Write, MSAC2_Read and MSAC2_Abort mes-
sages make use of slot 0, index 47.
Note The OMRON web-site (http://industrial.omron.eu) provides function blocks
that automate parameter access when using the CJ1W-PRM21 / CS1W-
PRM21 version 3.0 or newer. These function blocks automate the DP-V1
Class 2 related commands to the PROFIBUS master as well as the DP-V1
parameter channel request and response formats. You can skip this section if
you are using these function blocks.
