Modbus coils 0000h though 000Fh offer a large amount of functionality. The
intelligent input terminal overrides (Coils 0007h though 000Dh) for example
can be used to control any of the Inverter's assignable input terminal functions
(Refer to section 3-7-2 of the MX2-A@ Inverter user's manual). The following
example illustrates how to map Modbus coils 0000h though 000Fh into PZD3:
Set parameters P162 to 1F01h to map coil data 0 into output PZD3.
Restart the Inverter or reset the Option Board for the changes to take effect.

It is not possible or practical to use all the coils contained in Coil data 0 when
the Option Board is using the PROFIdrive device profile:
• The operation (0001h) and rotation direction (0002h) coils are not used by
the Inverter when the run command source (A002) is set to 4 (Option
Board).
• The trip reset coil (0004h) duplicates the functionality of Rst in STW.
• The operation status coil (000Fh) is not writeable.
The Modbus coils 0000h though 000Fh are now available for use via PZD3.
Use parameters C001 to C007 to assign Inverter functions to any of the intelli-
gent input terminals (Section 3-7-2 of the MX2-A@ Inverter user's manual). To
activate an assigned function, set the corresponding input terminal override
(bits 7 to 13 in coil data 0).
In addition to frequency control, the MX2-A@ Inverter allows direct control of
the motor torque.
Before following this example, disconnect your motor from any load to prevent
injury or damage to property.
The following example explains how to make use of the Option Board to con-
trol the motor torque:
Set parameter P162 to 1F01h to map coil data 0 into output PZD3.
Set parameter P163 to 1622h to map the torque command level input (P034)
into output PZD4.
Set parameter P173 to 1010h to map the torque monitor (d012) into input
PZD4.
Restart the Inverter or reset the Option Board for the new settings to take
effect. If the Inverter trips after restarting with an E64 and parameters P162,
P163 and P172 appear to be configured correctly, it is likely that you made a
