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 Operating Instructions 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 for which can
also be found in the drives 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 (see drive Installation and
Operation manual 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)
