Application Overview 2-14
‹ General Purpose Setup - nviWriteParamNum, nviWriteParamVal
Two network variables are defined for setting any drive parameter:
nviWriteParamNum - Specifies the drive parameter to be set. Writing to this point initiates the write sequence. Refer to the appropriate drive
user, parameter access, programming and/or technical manual for detailed information on drive parameters. The
parameter addresses in the above manuals is supplied in hexadecimal format. Refer to your system documentation to
determine the correct radix for the values entered. The default radix is decimal.
If an invalid parameter address is entered, 65535 (0xFFFFh) will be returned in nvoReadParamVal.
nviWriteParamVal - Specifies the value to be written to the specified parameter. Writing to this point completes the write sequence and causes
the value to be sent to the drive. Refer to the appropriate drive user, parameter access, programming and/or technical
manual for a detailed description of all parameters. The parameter values in the above manuals may be supplied in either
hexadecimal or decimal format. Refer to your system documentation to determine the correct radix for the values
entered. The default radix is decimal.
Note: The increment listed in the technical manual must be considered when specifying a value. For example, to set parameter b2-04,
DC Injection Time at Stop, to 1.00 seconds, nviWriteParamVal must be set to 100, since the increment for this parameter is 0.01
seconds.
