7.5 Parameter Management (Read/Write)
Parameter values can be read from or written to the soft
starter.
If output register 57 of the scanner is greater than 0, the
EtherNet/IP interface writes all parameter registers to the
soft starter.
Enter the required parameter values in the output registers
of the scanner. The value of each parameter is stored in a
separate register. Each register corresponds to 2 bytes.
•
Register 57 (bytes 114–115) corresponds to
parameter 1-1 Motor Full Load Current .
•
The VLT
®
Soft Starter MCD 500 has 109
parameters. Register 162 (bytes 324–325)
corresponds to
parameter 16-13 Low Control Volts .
NOTICE
When writing parameter values, the EtherNet/IP Interface
updates all parameter values in the soft starter. Always
enter a valid value for every parameter.
NOTICE
The numbering of parameter options via fieldbus
communications differs slightly from the numbering
shown on the LCP. Numbering via the Ethernet Module
starts at 0, so for
parameter 2-1 Phase Sequence , the
options are 1–3 on the LCP but 0–2 via the module.
