CAPTURE, Capture exact time <strong>of</strong> external events<br />

The RD1.Pos at the time <strong>of</strong> the event. The RD1.Pos is<br />

sampled with the FS (currently 1000 Hz) frequency, and<br />

the resulting position is then interpolated from that<br />

position and speed. Captured and interpolated RD1.Pos.<br />

Capture.RPos 4 -2 31 ..2 31 -1 R<br />

Same as Capture.Pos, but affected by PG.PosOffs<br />

Capture.Enable 5 0..3 RW<br />

Control and indicate operation <strong>of</strong> the CAPTURE<br />

mechanism. Capture.Enable is cleared<br />

when the event<br />

occurs and therefore, must be re-enabled every time a<br />

new capture is desired.<br />

Bit0 (1) = 1 Enable this function and PL-code captures interrupt.<br />

Bit0 (1) = 1<br />

Bit1 (2) = 1<br />

The mode for rapidly stopping the motor.<br />

Capture.Speed 6 -32767000 .. 32767000 R<br />

The current value <strong>of</strong> RD1.Speed when the event<br />

occurred. Captured RD1.Speed.<br />

Capture.SetTorque 7 -32767 .. 32767 RW<br />

Capture.SetTorque and<br />

Capture.SetPHDelay values are used during/after the<br />

HSI capture interrupt is executed. The HSI capture<br />

interrupt can be used if a minimum delay start or stop <strong>of</strong><br />

the motor is desired. The interrupt does the following:<br />

OR Reg.Mode, 128 ; Turn <strong>of</strong>f regulator output.<br />

LET Reg.Torque = Capture.SetTorque ; Set user specified torque<br />

LET Motor.PhDelay<br />

= Capture.SetPhDelay ; Set optimum commutation<br />

for fast ACC/DECEL.<br />

; The user Capture interrupt routine is then called to do the<br />

remaining control.<br />

Capture.SetPHDelay 8 -32767 * FS .. 32767 * FS R<br />

See Capture.SetTorque for description.<br />

Capture.GPos 9 -2 31 ..2 31 -1 R<br />

Captured the Gear.Pos interpolated<br />

to the time <strong>of</strong> the<br />

event. The Gear.Pos is sampled with the FS (currently<br />

1000 Hz) frequency, and the resulting position is then<br />

interpolated from that position and speed.<br />

Capture.GSpeed 10 -32767 * FS .. 32767 * FS R<br />

Captured the Gear.Speed to the time <strong>of</strong> the event.<br />

Capture.APos 11 -2 31 ..2 31 -1 R<br />

Captured the Pg.APos at the time <strong>of</strong> the event.<br />

See “Compatibility issue”.<br />

Capture.ASpeed 12 -32767 * FS .. 32767 * FS R<br />
