Encoder output pulse setting selection (refer to parameter No.PA15).
0: Output pulse designation
1: Division ratio setting
2: Ratio is automatically set to command pulse unit
Setting "2" makes the parameter No.PA15 (encoder output pulse)
setting invalid.

name and
function
column.
PC20 *SNO Station number setting
Used to specify the station number of the servo amplifier for RS-422
communication.
Always set one station to one axis of servo amplifier. If one station number
is set to two or more stations, normal communication cannot be made.

PC21 *SOP RS-422 communication function selection
Select the communication I/F and select the RS-422 communication
conditions.
0 0
RS-422 communication baud rate selection
0: 9600 [bps]
1: 19200 [bps]
2: 38400 [bps]
3: 57600 [bps]
4: 115200[bps]
RS-422 communication response delay time
0: Invalid
1: Valid, reply sent after delay time of 800 s or more
0000h Refer to
name and
function
column.
PC22 *COP1 Function selection C-1
Select the encoder cable communication system selection.
0 0 0
Encoder cable communication system selection
0: Two-wire type
1: Four-wire type
Incorrect setting will result in an encoder alarm 1
(A16) or encoder alarm 2 (A20).
