Sequence Operation
Besides the standard fastening procedures of Parameter 1 ~ 64, two types of sequence operation modes,
which are available for accommodating applications requiring a complex process, are provided.
64 types of fastening parameters can be used to program up to 8 stages.
Batch sequence: Multiple parameter settings are used and at each stage, an operation, each requiring a
separate start signal, is repeated for the number of times designated by “Count.”
Continuous sequence: Up to 8 stages of operation with multiple parameter settings are executed successively.
A single start signal must be sustained and held until the required sequences are completed.
The designation of a Sequence Operation Mode besides “0: Standard Operation” shall be handled as a sequence
setting with Work Select No.=Parameter No.
[Precautions on the Sequence Operation Mode]
・Input the start signal via the external IO or the start lever of the tool.
・Maintain the start signal for the sequence operation. (Deadman circuit)
・The sequence operation immediately stops with any NG during it.
・The OK signal outputs only when the sequence operation normally completes.
・Results of each stage are saved. (Result history, Waveform history, CF card)
・Waveform data is saved as a continuous data, except when free-run occurs.
*For continuous sequence, the waveform data for each stage (except for at the end of fastening)
cannot be read or saved via the HFC3000 user console.
(Only the torque-angle waveform (540deg fixed) is saved in the waveform history or the CF card.)
・Axis cycle count is incremented at the final stage.
D-No.580 Sequence Mode
0: Standard operation (sequence unavailable)
1: Batch sequence
2: Automatic Function 1 (REJECT is not output when the lever is switched off in the middle)
3: Automatic Function 2 (REJECT is output when the lever is switched off in the middle)

Setting ranges: 0~64(*D-No.581:1~64) /0~99 (times)/0~99 [×0.1 second]
Initial value: 000000 (*D-No.581:XX0000, XX=Parameter No.)
Precautions on setting [D-No.581 [Sequence Operation Stage 1]]
・Under the following settings: 1. Batch sequence, 2. Continual sequence 1, or 3. Continual
sequence 2, setting “0” as a parameter No. causes the abnormal signal A. 09-02 “Missing
Parameter Setting” to occur after the start signal is set to ON.
