2.12 S: Special Applications
Sequence Timer 1 has no effect on the drive Run command. The drive starts correctly based on the status of the Run
command source set in b1-02 [Run Command Selection 1].
• When S2-04 = 1 or 2 [Run or Run - PID Disable] and the terminal set for H1-xx = 51 is not active:
The drive will run during the active time of Sequence Timer 1 when the drive has a Run command. The drive uses
the frequency reference set in S2-05 [Timer 1 Reference Source]. When S2-04 = 2, PID control is disabled.
If you activate the input from the terminal set for H1-xx = 52 [Sequence Timer Cancel] while Sequence Timer 1 is
active, the timer will be disabled until the next scheduled sequence timer occurrence. To enable Sequence Timer 1
again, disable and enable the drive Run command again. While Sequence Timer 1 is active, the terminal set for H2-xx
= 51 [MFDO Function Selection = Sequence Timer 1] will be active regardless of the S2-04 setting.
When S2-01 = S2-02, Sequence Timer 1 is active continuously for the days set in S2-03. The timer will start at the S2-
01/S2-02 time on the first day and stop at the same time on the last day. When you set only one day in S2-03, the
timer will stop at 11:59 on that day. When S2-03 = 1 [Daily], the timer will run from the start/stop time until 11:59
every day.
HOA Keypad will show these messages to identify the status of the drive and Sequence Timer 1:
• Sequence Timer 1 RUN: S2-04 = 1 or 2, Sequence Timer 1 is active and the drive is running.
• Sequence Timer OFF: The drive has a Run command, S2-04 = 1 or 2 and Sequence Timer 1 is not active.
When the drive is in Sequence Timer OFF condition, the drive should not detect Uv [DC Bus Undervoltage] or ov
[Overvoltage] fault, but only detect as an alarm.
Note:
If S2-03 > 0 and the HOA keypad is not connected, the drive will detect oPr [Keypad Connection Fault]. The o2-06 [Keypad Disconnect
Detection] setting does not have an effect.
■
Sequence Timers 2 to 4
These timers operate identically to Sequence Timer 1. Parameters S2-06 [Timer 2 Start Time] to S2-20 [Timer 4
Reference Source] set Sequence Timers 2 to 4.
■
Priority
When more than one sequence timers overlap, the timer with the lowest number has priority.
• Sequence Timer 1 = highest priority
• Sequence Timer 4 = lowest priority
Note:
Jog Forward/Reverse has higher priority than any of the Sequence Timers.
Figure 2.111 shows an example of sequence timer operation when you set the drive parameters as specified in
2.68.
