4.25 TachoTerminal (tacho terminal to be used)
Depending on the analog tacho output voltage
- e.g. 60 V at 1000 rpm - and the maximum speed of the drive
system
- which is the maximum of SpeedScaleAct (2.29), M1OvrSpeed (30.16) and M1BaseSpeed (99.04) -
different inputs connections at the SDCS
-CON-F have to be used:
TachoTerminal (4.25)
shows which terminal has to be used depending on the setting of M1TachoVolt1000
(50.13)
and the actual maximum speed of the drive system:
0 =
NotUsed if M1TachoVolt1000 (50.13) = 0 V, no analog tacho used or not set jet
1 =
X1:3 8-30V result if M1TachoVolt1000 (50.13) ≥ 1 V
2 =
X1:2 30-90V result if M1TachoVolt1000 (50.13) ≥ 1 V
3 =
X1:1 90-120V result if M1TachoVolt1000 (50.13) ≥ 1 V
4 =
Auto result if M1TachoVolt1000 (50.13) = -1 V after the tacho gain was successfully measured by
means of the speed feedback assistant

5.01 AITacho Val (analog input for tacho)
Measured actual
voltage at analog tacho input. The integer scaling may differ, depending on the connected
hardware and jumper setting.
Note
s:
−
This value is not valid, if an analog tacho is connected!
−
A value of 11 V equals 1.25 * M1TachMaxSpeed (88.25)
