PID Control (Upper Limit of PID Output Limiter, Lower Limit of PID Output Limiter)
The upper and lower limiters can be specified to the PID output, exclusively used for PID control. The
settings are ignored when PID cancel
Hz/PID is enabled and the inverter is operated at the standard
frequency previously set.
(
Function code E01 to E09, data = 20)
PID Control (Upper limit of PID output limiter) (J18)
J18 sets the upper limit of the PID controller output limiter in %. If you specify "999," the setting of the
frequency limiter (High) (F15) will serve as the upper limit.
PID Control (Lower limit of PID output limiter) (J19)
J19 sets the lower limit of the PID controller output limiter in %. If you specify "999," the setting of the
frequency limiter (Low) (F16) will serve as the lower limit.
J21
Dew Condensation Prevention (Duty)
When the inverter is stopped, dew condensation on the motor can be prevented, by feeding DC power to the
motor at regular intervals to keep the temperature of the motor above a certain level.
Enabling conditions
The dew condensation prevention function gets started when the terminal command
DWP is set to ON while
the inverter is stopped.

Dew Condensation Prevention (Duty) (J21)
The current to the motor is controlled in duty according to the DC brake 1 (operation level) (F21) and the
ratio of the dew condensation prevention duty (J21) to the DC brake 1 (time) (F22).
