Accessing Parameters
Section 4-5
!Caution
Do not access Inverter parameters while the Inverter is being re-initialized.
Refer to the MX2 Inverter manual section 6-3.
Refer to the RX Inverter manual section 4-2.
Accessing parameters during a re-initialization will cause the Inverter to go
into an undefined state.
4-5-2 PROFIdrive DP-V1 Parameter Channel
The 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.
!Caution
Do not access Inverter parameters while the Inverter is being re-initialized.
Refer to the MX2 Inverter manual section 6-3.
Refer to the RX Inverter manual section 4-2.
Accessing parameters during a re-initialization will cause the Inverter to go
into an undefined state.
4-5-2-1 Opening and Closing a DP-V1 Channel
Before the PROFIBUS master can exchange information with the Option
Board, the PROFIBUS master has to open a DP-V1 Class 2 (MSAC2) chan-
nel to the Option Board. Please consult the documentation of your PROFI-
BUS master on how to achieve this.
The Option Board only supports one DP-V1 Class 2 (MSAC2) channel. It is
therefore advisable to close the channel when you are done. Not doing so will
block other users of the parameter channel. Consult the documentation of
your PROFIBUS master on how to achieve this.
