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

4.26 IactScaling (scaling of the fixed actual current output I-act)
Scaling of analog output for the actual output current in Ampere per 10 V output voltage.
See SDCS-CON-F X2:9.

Group 5: Analog I/O
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.
Notes:
−
This value is not valid, if an analog tacho is connected!
−
A value of 11 V equals 1.25 * M1TachMaxSpeed (88.25)

5.03 AI1 Val (analog input 1 value)
Measured actual voltage at analog input 1. The integer scaling may differ, depending on the connected
hardware and jumper settings.
