Parameter H5-04 - Stopping Method after Serial Communication Error
Parameter H5-04 (or Modbus Register 41Fh) is used to determine the method of stopping the
motor if there is a communication error. The table below indicates the stopping methods that can
be used when a communication error occurs.
Setting Value (in hex)
The default setting of parameter H5-04 is ë3í.
Parameter H5-05 - Serial Fault Detection Selection
Parameter H5-05 (or Modbus Register 420h) is used to enable or disable the Time-out detection.
The table below indicates how to enable or disable the communication error.
Setting Value (in hex)
The default setting of parameter H5-05 is '1'.
Parameter o2-09 - Initial Mode Select
Parameter o2-09 (or Modbus Register 50Dh) determines the Modbus Register Address of the
operational signals register and frequency reference register. Set this parameter to ë1í so that the
Modbus Register Addresses of the Operation Signal register is 001h and the Frequency
Reference register is 002h. The Modbus Register Address for Operation Signals is 00h and the
Frequency Reference register is 01h for flach software versions previous to '1024' and CPU
version '20'.
The default setting for parameter o2-09 is '0'.
