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.

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 "Ethernet Modbus". This setup assumes that an
existing working TCP/IP network is established.
2. Verify the network settings for the parameters 'Subnet mask' and 'Gateway address' . Refer
to Tables titled Network 1: TCP/IP Setup Menu. and Network 1: TCIP/IP Setup Menu
located in the previous section of this chapter to find the parameter numbers for the
'Gateway Address' and the 'Subnet Mask' based on the NXGpro software version and
hardware configuration.
3. Set parameter 'IP Address'. The IP address must be unique to the drive. Refer to Tables
titled Network 1: TCP/IP Setup Menu. and Network 1: TCIP/IP Setup Menu located in the
previous section of this chapter to find the parameter number for the 'IP Address' based on
the NXGpro software version and hardware configuation.
4. Set parameter 'Net Control Type' (9944) to "SOP". This makes the definitions of the fixed
register bits in register 'Data to Drive 01' programmable.
