Fast Setup: Send a motor speed setting to the drive

1. Using parameter 'Velocity Units' (9080), set the desired speed units to be sent to the drive,
to one of the following options:
– %
– RPM
– Hertz
2. The PLC needs to send the desired speed setting to the drive in register 'Data to Drive 02' .
This register is reserved to hold speed settings only, as noted in Table
between Drive Parameter ID and Communication Protocol Address in Section Parameter
Assignment/Addressing.
3. Send 0x61 in register 'Data to Drive 01' . The motor now accepts the speed setting from
the PLC.
9.4.4 Fast Setup: Control the drive using user-defined bits controlled by the SOP
To control the drive using non-default configuration, you must redefine the fixed register bits
at register 'Data to Drive 01'.
Note
The 'fixed reg bits' location is fixed at register 'Data to Drive 01', whether the default
configuration is used or not.
You cannot reprogram the 'fixed reg bits' location.
You can reprogram the definition of the bits at this address.
To control the drive this way, complete the following steps.
1. Set parameter 'Network 1 Type' (9901) to "ControlNet".
2. Set parameter 'ControlNet Address' (9903) to the desired network address for the drive.
3. Set parameter 'Net Control Type' (9944) to "SOP". This makes the definitions of the fixed
register bits in register 'Data to Drive 01' programmable.
4. Next, set up the drive to correspond with the bits you want to use in the SOP. Refer to
Section
variable, and use the procedures detailed in this section to complete set up.
5. To enable speed settings from the network, add the following line to the SOP file:
RawDemandNetwork1_O =
