7.1 Analog inputs changeover
Control signal terminals 4 and 6 can be used as analog inputs (AI). The corre-
sponding signal range will depend on parameter P-16 for analog input AI1
and parameter P-47 for analog input AI2.
The reference potential for the two analog inputs AI1 and AI2 is 0 V (control
signal terminals 7 and 9).
With the default settings, control signal terminal 6 (AI1) will be configured for
a setpoint voltage of 0 to +10 VDC and control signal terminal 4 as a digital
input (DI3).
Example
Desired options:
• Analog input AI2 suitable for 4 to 20 mA with wire breakage monitoring.
• Switching the setpoint source between AI1 and AI2 via DI2.
Figure 72: Switching setpoint sources
Table 13: Analog and digital input wiring (P-12 = 0, P-47 = t4-20)
• DI1 (control signal terminal 2): FWD (Forward = Start enable clockwise
rotating field)
• DI2 (control signal terminal 3): AI1/AI2 (change of setpoint source from
AI1 to AI2)
• AI1 (control signal terminal 6): analog setpoint value 1
• AI2 (control signal terminal 4): analog setpoint value 2
￫
The function of control signal terminals 4 and 6 is defined by the
selection made in parameter P-15 and depends on the control
mode in parameter P-12.
