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 MX2-A@ Inverter,
keep the sign of HIW and P034 the same.
The torque direction is controlled by the sign of HIW when using the MX2-A@
Inverter revision AAAA. On later releases, the sign of P034 controls the torque
direction.
Before you start customising the process area, it is necessary to note the
Inverter places some restrictions on the customisation. Sections 5-1-2 Config-
uration Errors and 5-2-2 Extended Diagnostic Information of this manual will
assist you when your configuration is rejected by the Inverter. You can how-
ever avoid your configuration being rejected by observing the following rules:
• 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-A@ 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).
• Only map a Modbus registers in the output process area if it is writeable.
A register is writeable if it has an 'R/W' or a 'W' in the 'R/W' column in sec-
tion B-4-2 of the MX2-A@ Inverter user's manual.
• Only map a Modbus register in the output process area if it is run-mode
editable. Refer to section 3-2-3 of the MX2-A@ Inverter user's manual for
an explanation of run-mode editable registers. Also note that the run-
mode edit requirement can be disabled with b031.
