5.2 b: ApplicationYASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 167Parameter Details5 b4-01, b4-02: Timer Function On-Delay, Off-Delay Timeb4-01 sets the on-delay time for switching the timer output. b4-02 sets the off-delay time for switching the timer output. Timer Function OperationWhen the timer function input closes for longer than the value set in b4-01, the timer output switches on. When the timerfunction input is open for longer than the value set in b4-02, the timer output function switches off. Figure 5.24demonstrates the timer function operation.Figure 5.24Figure 5.24 Timer Operation b4-03 to b4-08: H2- ON-Delay and OFF-Delay TimeSets the length of the delay time for contact outputs to open or close for the related functions set in H2-.Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.Note: Even if the length of the off-delay time and on-delay time for multi-function digital output are each less than 100 ms,the multi-function digital output closes for at least 100 ms. b5: PID ControlThe drive has a built in PID (Proportional + Integral + Derivative) controller that can be used for closed loop control ofsystem variables such as pressure, temperature, and so on. The difference between the target and the feedback value(deviation) is fed into the PID controller. The PID controller adjusts the drive output frequency in order to minimize thedeviation, providing accurate control of system variables. P ControlThe output of P control is the product of the deviation and the P gain so that it follows the deviation directly and linearly.With P control, only an offset between the target and feedback remains.No. Name Setting Range Defaultb4-01 Timer Function On-Delay Time 0.0 to 3000.0 s 0.0 sb4-02 Timer Function Off-Delay Time 0.0 to 3000.0 s 0.0 sNo. Name Setting Range Defaultb4-03 H2-01 ON Delay Time 0 to 65536 ms 0 msb4-04 H2-01 OFF Delay Time 0 to 65536 ms 0 msb4-05 H2-02 ON Delay Time 0 to 65536 ms 0 msb4-06 H2-02 OFF Delay Time 0 to 65536 ms 0 msb4-07 H2-03 ON Delay Time 0 to 65536 ms 0 msb4-08 H2-03 OFF Delay Time 0 to 65536 ms 0 msb4-01 b4-02 b4-01 b4-02Multi-function ContactInput: Timer Function (H1- = 18) On (Closed)Off (Open)On (Closed)Off (Open)Multi-function ContactOutput: Timer Function (H2- = 12)ON ONON ONONON ONONInternal data of H2-01Multi-Function DigitalOutputs of H2-01b4-03 b4-04 b4-03On (Closed)Off (Open)b4-04Time period that the multi-functiondigital output is closed ≥ 100 msTime period that the multi-functiondigital output is closed < 100 msTime period that the multi-functiondigital output is closed = 100 msOn (Closed)Off (Open)
