J516 External PID Control 1 (Proportional operation output convergent value)
J616 (External PID Control 2 (Proportional operation output convergent value))
J666 (External PID Control 3 (Proportional operation output convergent value))
Exclusively for external PID control, this setting value can be added to the external PID
output. J516/J616/J666 sets external PID controls 1/2/3 respectively.
- Data setting range: 1 to 150 (%)
Also, by disabling I (integral time) and D (differential time) to enable only P (gain) and this
value, the following comparison is possible.
