6. PARAMETERS
No. Symbol
PC19 *ENRS Encoder output pulse selection
Use to select the, encoder output pulse direction and encoder output
pulse setting.
0 0
Set value
0
1
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.
PC20 *SNO Station number setting
Used to specify the station number for RS-422 serial communication and
USB 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
PC22 *COP1 Function selection C-1
Select the encoder cable communication system selection.

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
0 0
Encoder cable communication system selection
0: Two-wire type
1: Four-wire type
The following encoder cables are of 4-wire type.
MR-EKCBL30M-L
MR-EKCBL30M-H
MR-EKCBL40M-H
MR-EKCBL50M-H
The other encoder cables are all of 2-wire type.
Incorrect setting will result in an encoder alarm 1
(A16) or encoder alarm 2 (A20).
