External PID Control 1 (Upper limit of PID process output)
(Lower limit of PID process output)
(Upper and lower limits)
J618 (External PID Control 2 (Upper limit of PID process output))
J619 (External PID Control 2 (Upper limit of PID process output))
J620 (External PID Control 2 (Upper and lower limits)
J668 (External PID Control 3 (Upper limit of PID process output))
J669 (External PID Control 3 (Upper limit of PID process output))
J670 (External PID Control 3 (Upper and lower limits)
J518/J519/J520, J618/J619/J620 or J668/J669/J670 define the upper and lower limiters for
the external PID output, which exclusively apply to external PID control 1, 2 or 3,
respectively.
When external PID control is canceled with %/
EPID1 , %/ EPID2 or %/ EPID3 and manual
command is used to operate, the upper and lower limiters are effective.
E01 to E07, data = 202 ( %/EPID1 ), 212 ( %/EPID2 ), 222 ( %/EPID3 )
„ PID Control 1 to 3 (Upper limit of PID process output) (J518, J618, J668)
- Data setting range: -10 to 110 (%)
J518/J618/J668 specifies the upper limit of the external PID processor output limiter in %.
„ PID Control 1 to 3 (Lower limit of PID process output) (J519, J619, J669)
- Data setting range: -10 to 110 (%)
J519/J619/J669 specifies the lower limit of the external PID processor output limiter in %.
„ PID Control 1 to 3 (Upper and lower limits) (J520, J620, J670)
- Data setting range: 0, 1
J520/J620/J670 specifies the upper and lower limits of the external PID processor output
limiter.
