YASKAWA TM.iQp.02 iQpump Drive Programming Manual 23
◆ b4 Delay Timers
The iQpump drive has an internal timer function that operates independently from the Drive. A digital input must be programmed to be a
timer start input by setting H1-0x = 18. A digital output must be programmed as a timer output by setting H2-0x = 12. (Not to be
confused with the “Wait to Run Time” in b1-11.)
■ b4-01 Timer Function ON-Delay Time
Setting Range: 0.0 to 3000.0 sec
Factory Default: 0.0 sec
The timer start input (H1-0x = 18) must be held on for at least the time specified in parameter b4-01 before the digital output programmed
as the timer output will close. See Figure 20 for timing details.
■ b4-02 Timer Function OFF-Delay Time
Setting Range: 0.0 to 3000.0 sec
Factory Default: 0.0 sec
The timer start input (H1-0x = 18) must be held off for at least the time specified by b4-02 before the digital output programmed as the
timer output will open. See Figure 20 for timing details.
