J551
J552
J553
J550, J551, J552 and J553 define an external PID control command as a preset value (3
steps).
 External PID multistep command (Mode selection) (J550)
J550 selects an external PID control under which an external PID multistep command takes
effect.
- Data setting range: 0 bit, 1 bit, 2 bits
Data for J550
0-2 bit = 0
0 bit = 1
1 bit = 1
2 bits = 1
 External PID multistep command (Multistep command 1 to 3) (J551, J552, J553)
J551/J552/J553 specifies a multistep command in a physical quantity.
- Data setting range: -999.00 to 0.00 to 9990.00
