■ Motor increase judgment (Duration time) (J451)
The duration time of motor increase judgment frequency is specified.
- Data setting range: 0.00 to 3600 s
■ Motor decrease judgment (Judgment frequency) (J452)
Motor decrease judgment frequency is specified.
- Data setting range: 0 to 120 Hz, Inherit
Data for J450 Description
0 to 120 Hz Motor decrease judgment frequency
Inherit Depends on the PID control (PID output limiter upper limit) (J118, J218)
■ Motor decrease judgment (Duration time) (J453)
The duration time of motor decrease judgment frequency is specified.
- Data setting range: 0.00 to 3600.00 s
J454 Contactor Restart Time when Switching the Motor
■ Contactor restart time during motor switching (J454)
In the inverter drive motor floating system (J401 = 2) and inverter drive motor fl
commercial power-driven motor system (J401 = 3), the motors are operated by delaying
starting inverter-driven motors or commercial power-driven motors when the number of
motors is increased or regular switching is implemented. The delay time (relay or contactor
activation delay time) is specified.
- Data setting range: 0.01 to 2.00 s
