Programming Parameters
10 Programming Parameters
Registers #100-399 are programming parameters used to set up the drive for a specific application. For details
regarding these registers, refer to the SMV Operating Instructions (SV01) that accompanied the drive.
Registers #400-499 are communication specific programming parameters and will vary depending on which, if
any, of the optional communication modules is installed in the drive. Refer to Section 4.1 for details regarding the
communication registers associated with the RS-485 communication module.
Registers #500-599 are read-only drive diagnostic parameters, the details of which can also be found in the drive’s
operating instructions.
There is a direct correspondence between the Drive Programming Parameter numbers and the register numbers
used in the Modbus messages. For example, if you want to read Drive Programming Parameter P103 (Maximum
Frequency) over the Modbus network, you would read register #103.
10.1 Negative Number Transmission
Drive parameters P160, P161, P204, P205, P214, P215, P231, P232, P233, P522, and P523 are signed integer
values and could be negative (refer to the SMV Operating Instructions, SV01, for details on these parameters).
These registers are sent over the modbus communications in signed internal units. For example: A preset PID
setpoint value of 500.0 would be transmitted as 5000 (13 88 hex). A preset PID setpoint value of -500.0 would be
transmitted as -5000 (EC 78 hex).
10.2 Terminal and Protection Status (P530)
When a read command is issued over the Modbus network to Programming Parameter P530 (register #530), the
Terminal and Protection Status data returned is shown in Table 16.
