Next test procedure will help you to understand the protocol programming.
(1)Servo ON/OFF command purpose of command
* In case of Ezi-STEP Plus-R : Jump to next step(‘(2)Motion Command’), because
the motor is ready to move status after Power ON.
The header and tail information is needed for protocol programming.
Additionally Frame Data (Slave ID, Frame type, Data and CRC) is also needed in each one
of protocol with header and tail.
1) Select ‘Comm Port’ number and ‘Baudrate’, and click ‘Connect’ button.
2) Header: Click ‘Header’ and you can see ‘[0xAA][0xCC]’ on ‘Send Buffer’ window.
3)Slave ID : Insert your connected slave number(above example is ‘0’) and click
‘SlaveNo’.
4)Frame type : Select ‘Frame type’.
You can find next table information in ‘1-2-1. Frame Type and Data Configuration ’
on UserManual(Ezi-SERVO Plus-R)_Communication Function about Servo ON/OFF command .
Insert ‘42’ in area and click ‘1 byte’ because the size of F rame Type is 1 byte.
5) Data: To make Servo ON status, the data is ‘1’so insert ‘1’ in area and
click 1 byte’.
6) CRC: Click ‘CRC’ and the automatically calculated result value (2 bytes) is displayed
on ‘Send Buffer’ window.
