14. COMMUNICATION FUNCTIONS

14.12.11 Other commands

(1)Servo motor end pulse unit absolute position

Read the absolute position in the servo motor end pulse unit.

Note that overflow will occur in the position of 16384 or more revolutions from the home position.

(a)Transmission

Send command [0][2] and data No. [9][0].

Command	Data No.
[0][2]	[9][0]

(b)Reply

The slave station sends back the requested servo motor end pulses.

Absolute value is sent back in hexadecimal in the servo motor end pulse unit.

(Must be converted into decimal)

For example, data "000186A0" is 100000 [pulse] in the motor end pulse unit.

(2)Command unit absolute position

Read the absolute position in the command unit.

(a)Transmission

Send command [0][2] and data No. [9][1].

Command	Data No.
[0][2]	[9][1]

(b)Reply

The slave station sends back the requested command pulses.

Absolute value is sent back in hexadecimal in the command unit.

(Must be converted into decimal)

For example, data "000186A0" is 100000 [pulse] in the command unit.

(3)Software version

Reads the software version of the servo amplifier.

(a)Transmission

Send command [0][2] and data No.[7][0].

Command	Data No.
[0][2]	[7][0]

(b)Reply

The slave station returns the software version requested.
