The arrangement of the terminal assignment data permits you to assign all inputs in a single 
command. The example below shows a transmission to  the inverter at address Node 1 to set the 
Forward command, Multi-sp eed 1 and Multi-speed 2.
Command – 03The 03 command reads the monitor data as a single block.
The frame format of command 03 follows the 
diagram and specification table. The transmit 
frame has no data field.
The receive frame has a 104-byte data field,...

The data in the receive frame contains 8-byte values for 13 items, listed in the table below:
The eight bytes for intelligent inpu t or intelligent output data have a bit set in the data field for 
each I/O point that is ON, according to the following table:

Command – 04The 04 command reads the status of the inverter. 
The frame format of command 04 follows the 
diagrams and specification tables. The transmit 
frame has no data field.
The receive frame has an 8-byte data field, 
containing values for three trip items (plus a 
reserved field).
Trip data is organized as shown. The 
table below lists the codes and their 
meanings.

Command – 05The 05 command reads the inverter’s trip history. 
The frame format of command 05 follows the 
diagrams and specification tables. The transmit 
frame has no data field.
The receive frame has a 440-byte data field. This 
consists of an 8-byte total accumulated number of 
trip events, followed by six 72-byte strings for the 
six most recent trip events as shown below.
   
The nine bytes of data for each trip event histor y is listed below. The data...

For Command 05, bytes 2, 3, and 4 of 
the event history are status codes A, B, 
and C, respectively. The tables below 
provide status code descriptions.

Command – 06The 06 command reads a single parameter 
value from the inverter, which is specified by 
the data field this read command.
The receive frame includes an ACK 
(acknowledge) character, followed by an
8-byte data field.
Use the codes in the table below to return parameters for H003 and H203 (motor capacity 
selection).

Command – 07The 07 command sets a parameter value equal to the value specified in the transmission. The 
frame format of command 07 follows the diagram and specification table.  
Note that the parameter F001, the output frequency,  can be set more directly with host 
command 01 instead of with this command. Use  the codes in the following table for setting 
parameters associated with H003 and H203.

Command – 08The 08 command initializes the inverter parameters to the factory default values. First, you 
must set B84 (use command 07) to specify whethe r you want to clear the trip history at the 
same time. Also, set B85  to specify the country code for th e initialization (use command 07).
The frame format of command 08 follows the 
diagram and specification table.

Command – 0AThe 0A command sets a value in the EEPROM.
The frame format of command 0A follows the 
diagram and specification table.
Command – 0BThe 0B command recalculates the inverter’s internal motor constants. Use this function after 
the base frequency or any Hxxx parameters  are changed via the serial link commands. 
The frame format of command 0B follows the 
diagram and specification table.
