Timer specifications
• SD803 is required for connect/disconnect of SSCNET communication and
start/release of amplifier-less operation.
0 : No command
1 to 32 : Disconnect command of SSCNET communication
-10 : Connect command of SSCNET communication
-20 : Start command 1 of amplifier-less operation (EMI invalid)
-21 : Start command 2 of amplifier-less operation (EMI valid)
-25 : Release command of amplifier-less operation
-2 : Execute command
• The "write/read request" is executed after setting of the axis No. and servo
parameter No.
1: Write request
2: Read request
3: 2 word write request
4: 2 word read request
• "0" is automatically set by Motion CPU after completion of servo parameter
write/read request. ("-1" is stored by Motion CPU at write/read error.)
• The axis No. to write/read servo parameter is stored.
Q173DSCPU: 1 to 32
Q172DSCPU: 1 to 16
• The servo parameter No. to be written/read is stored in hexadecimal.
H
• VC series use
H
• The setting value of servo parameter to be written is stored when "1: Write
request" is set in SD804.
• The setting value of servo parameter to be written is stored when "3: 2 word
write request" is set in SD804.
