Signal Source Note
Name Type DIS DIS format CFG List
CLUTCH2−CLOSE d 1417/1 bin 1416/1 2 HIGH: Close clutch
LOW: Open clutch
CLUTCH2−SEL d 1417/2 bin 1416/2 2 HIGH: Close clutch immediately
LOW: Wait for position setpoint, then close
CLUTCH2−SET ph 1419/1 inc 1418/1 3 Setpoint position of X axis (line shaft)
CLUTCH2−ACT ph 1419/2 inc 1418/2 3 Actual position of X axis (line shaft)
CLUTCH2−LEN ph 1419/2 inc 1418/2 3 Clock pulse length (X axis)
CLUTCH2−OPEN d − − − − HIGH: Clutch open
LOW: Clutch engaged
CLUTCH2−START d − − − − HIGH: Clutch received command to close
CLUTCH2−DIR−ERR d − − − − HIGH: Error of direction of rotation
CLUTCH2−SET—ACT ph − − − − Output of the differential signal of
CLUTCH2−ACT – CLUTCH2−SET if CLUTCH2−CLOSE = HIGH
·
The output corresponds to the distance still to be
compensated
·
The output refers to the set acceleration ramp and can take
several clock pulses
CLUTCH2−DIST ph − − − − Distance required for acceleration
CLUTCH2−PHOUT ph − − − − Output of the "internal" master angle position
·
The signal refers to one machine pulse (0 ... CDATA−ACTLEN)
·
Can be used as input signal for CDATA−XIN
·
The "external" master angle is applied to CLUTCH2−SET. If
the clutch is closed, the "external" and "internal" master
angles are identical.
CLUTCH2−NSET phd − − − − Speed setpoint
Function
l Clutch engagement through ramp function with following synchronous running (chapter
3.2.23.1)
l Direct clutch engagement (chapter 3.2.23.2)
l Clutch disengagement (chapter 3.2.23.3)
