(3) Command classification
Command classification exists in the data frame sent by main machine, which is
used to define tasks of the frame data to be completed. Frame size varies based
on different command classification. Command classification is defined as below:
Data
0
1
2
3
4
5
6～F
Operation
Read status and feature information of slave machine
Read running parameters of slave machine
Read function code parameters
Modify function code parameters in inverter RAM area and to be lost
after power down (Not to be saved)
Send control command
Modify function code parameters in inverter EPROM area and to be
saved after power down
Reserve
(4) Operation command
The upper machine transmits operation command to slave machine, which exists
in all types of data frame (main machine send the 4th and 5th bit). The operation
command is defined as below:
Data
00H
Operation
Invalid command
01H
FWD running start
02H
REV running start
Data
10H
11H
12H
Operation
Set running frequency of slave
machine
Frequency setting of tape running in
FWD running start
Frequency setting of tape running in
REV running start
03H
Stop
13H
