This parameter shows the module type and SW version number as
detected by the drive. The value cannot be adjusted by the user. (If this
parameter is undefined, the communication between the drive and the
module has not been established.)
Shows the logical protocol on the hardware communication option
module (the NMBA-01 supports only the RTU mode) and the operating
mode of the watch-dog reset. There are two selections:
RTU wdg:flt
Remote Terminal Unit (RTU) mode. On a watch-dog error, the module
will indicate a watch-dog error. The module has to be reset (power off)
manually.
RTU wdg:rst
Remote Terminal Unit (RTU) mode. On a watch-dog error, the module
will reset itself.
Each device on the Modbus link must have a unique station number.
This parameter is used to define a station number for the drive it is con-
nected to.
Defines the communication speed in Baud. There are five selections:
1200, 2400, 4800, 9600 and 19200 Baud.
Defines the parity to be used with the Modbus communication. This
parameter also defines the number of stop bits in use. Typically with
Modbus communication the number of stop bits is 2 with no parity bit,
and 1 with even or odd parity. There are four selections:
EVEN, ODD, NONE 1 S.BIT and NONE 2 S.BIT.
