2-3-1 Main Functions
(1) Fastening Function
The HFC3000 SYSTEM is capable of the following fastening methods.
1. Torque method: Angle monitor, Torque rate monitor, 1/2/3 step fastening
2. Angle method: Torque monitor, Torque rate monitor, 1/2/3 step fastening
(2) Self-Check Function
When co
ntrol power is turned “ON”, the values of the torque tranducer ZERO voltage and CAL
voltage are acquired (these are reference values used for fastening). Before each fastening cycle, the
ZERO voltage and the CAL voltage of the torque transducer are acquired and compared to the
reference values from the power on check before the fastening operation is executed to confirm
proper torque transducer operation (the self-check is not executed in the case of reverse operation).
(3) Bypass Function
When a PLC Bypass input signal is activated, the Bypass output signal is activated. In this condition,
the spindle will not START, REVERSE, CAL OR RESET. If a BYPASS condition occurs during the
fastening operation, the fastening operation will stop.
(4) Abnormal Signal Output Function
Any system fault Abnormal state code numbers are displayed on the Controller (MFC) Unit front
panel.
If a system error occurs during a system check, connection check or overload check, an abnormal
signal will be output. In this situation, the STATUS LED (Red) on the unit will light up and an
abnormal state number and sub code will be displayed.
(5) Tool Type Checking Function
The parameter tool type and the connected tool type will be checked when the power turns on or the
tools are replaced. If the tool types are different, an abnormal will occur identifying that there is a tool
typre mis-match.
The tool ID contents are read in either of the following states;
1. If a tool is connected when the power is turned ON
2. When a tool is connected
