5.3.2 Assigning functions to digital inputs
Assigning control commands to digital inputs as command sources [P0701…P0709]
The digital inputs are pre-assigned with certain control commands in the factory. However,
these digital inputs can be freely assigned to a control command. Depending on the Control
Unit version, SINAMICS inverters are equipped with up to 9 digital inputs.
Table 5- 14 Factory setting of the digital inputs
Terminal no.: Digital input no. Control command Available in CU...
Terminal 5: Digital input 0 (DI0) Switch motor on/off (ON/OFF1)
Terminal 6: Digital input 1 (DI1) Reverse direction of rotation
Terminal 7: Digital input 2 (DI2) Fault acknowledgment
Terminal 8: Digital input 3 (DI3) Selects fixed frequency 1
Terminal 16: Digital input 4 (DI4) Selects fixed frequency 2
Terminal 17: Digital input 5 (DI5) Selects fixed frequency 3

Possible values for P0701 to P0709:
0: Digital input locked
1: Switch motor on/off (ON/OFF1)
2: Activate motor CW
3: Motor coasts to standstill (OFF2)
4: Rapid stop with ramp (OFF3)
9: Fault acknowledgement
10: Jog mode CW
11: Jog mode CCW
12: Change direction of rotation (reverse)
13: Increase frequency of motorized potentiometer
14: Increase frequency of motorized potentiometer
15: Select fixed frequencies (bit 0)
16: Select fixed frequencies (bit 1)
17: Select fixed frequencies (bit 2)
18: Select fixed frequencies (bit 3)
25: Enable signal for DC brake
27: Enable signal for PID technology controller
29: External fault
33: Disable additional frequency setpoint
99: The digital input can be freely used for the BICO technology
If you enable one of the digital inputs to be freely used for BICO technology (P701…P709 =
99), then you must interconnect this digital input to the required control command.
If value 99 is assigned to the digital input to define its function, this can only be reversed by
restoring the factory setting.
