Customising the Process Area
Section 4-3
Table 33 Output Process Area Configured with Forward Torque Command
The motor either accelerates or decelerates depending on the load. The out-
put frequency is limited by the P039 setting. The output torque is given by
d012 (input PZD4).
Step 12
To change the torque command direction, set both HSW=-1000 (10.00 Hz
reverse) and P034 (output PZD4)=-20 (20% reverse torque).
Table 34 Output Process Area Configured with Reverse Torque Command
The motor decelerates and accelerates in the opposite direction. The output
frequency is limited by the P040 setting. Note that the output torque given by
d012 (input PZD4) now has a negative sign to indicate that the torque direc-
tion is reversed.
Tip
To keep your application compatible with all revisions of the Inverter, keep the
sign of HIW and P034 the same.
The torque direction is controlled by the sign of HIW when using the Inverter
revision AAAA. On later releases, the sign of P034 controls the torque direc-
tion.

Mapping Restrictions
Before you start customizing the process area, it is necessary to note the
Inverter places some restrictions on the customizing.
If your configuration is rejected by the Inverter, you got assist in sections
5-1-
3 Configuration Errors
and
5-2-2 Extended Diagnostic Information
of this
manual.
If you want to avoid configuration rejection, observe the following rules for the
MX2:
• Set all unused PZDs to default by setting the associated configuration
register to 0.
• Only map Modbus registers listed in appendix B of the MX2 Inverter
user's manual.
• Do not map a Modbus register more than once in the output process
area.
• Always map both high- and low-words of a double-word Modbus register
next to each other in the process area. Also make sure that they are in the
correct sequence (high-word followed by low-word).
