Delta DVP-20PM

5 Applied Instructions and Basic Usage
Example 3
 If a communication timeout occurs, the data received is incorrect, or the values
of parameters of the instruction MODRD are incorrect when a DVP-10PM
series motion controller is connected to a VFD-B series AC motor drive (ASCII
mode: M1143=OFF), the sending of data will be retried.
 When X0 is ON, the DVP-10PM series motion controller used write H1770
(K6000) into the data address H0100 in the VFD-B series AC motor drive
whose device address is 01.
 If a communication timeout occurs, M1129 will be ON. If M1129 is ON, M1122
will be set to ON.
 If the data received is incorrect, M1140 will be ON. If M1140 is ON, M1122 will
be set to ON.
 If the values of parameters of the instruction MODWR is incorrect, M1141 will
be ON. If M1141 is ON, M1122 will be set to ON.
Processing the data received
Communication protocol: 9600,8,E,1
The communication protocol set is retained.
M1127 is reset.
Request for sending data
Communication command:
Device address: 01
Data address: H0100
Data: H1770
The reception
of data is complete.
When a communication timeout occurs, the sending of data is retried.
When the data received is incorrect, the sending of data is retried.
When the values of parameters of MODRD are incorrect, the sending of data is retried.
Communication timeout: 100 ms
The data received is stored in D1070~D1085 in the form
of ASCII characters.
M1129 is reset.

Example 4
 If a communication timeout occurs, the data received is incorrect, or the values
of parameters of the instruction MODRD are incorrect when a DVP-10PM
series motion controller is connected to a VFD-B series AC motor drive (ASCII
mode: M1143=OFF), the sending of data will be retried. The number of times
the sending of data is retired is stored in D0. The default value in D0 is 3. If
communication is retried successfully, users can control the communication by
means of triggering a condition.
 When X0 is ON, the DVP-10PM series motion controller used write H1770
(K6000) into the data address H0100 in the VFD-B series AC motor drive
whose device address is 01.
