Assigning functions to digital inputs
Assigning control commands to digital inputs as command sources [P0701…P0704]
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.
Table 6- 14 Factory setting of the digital inputs
Switch motor on/off (ON/OFF1)
Digital input 1 (DI1) Reverse direction of rotation
Digital input 3 (DI3) Selects fixed frequency 1
Table 6- 15 Changing the digital input settings
Extended access to the parameters
Digital input 0 (DI0)
P0701 = … Possible values for P0701 to P0704:
0: Digital input disabled
1: ON/OFF1
2: ON reverse /OFF1
3: OFF2 - coast to standstill
4: OFF3 - quick ramp-down
9: Fault acknowledge
10: JOG right
11: JOG left
12: Reverse
13: MOP up (increase frequency)
14: MOP down (decrease frequency)
15: Fixed frequency selector bit0
16: Fixed frequency selector bit1
17: Fixed frequency selector bit2
18: Fixed frequency selector bit3
22: QuickStop Source 1
23: QuickStop Source 2
24: QuickStop Override
25: DC brake enable
27: Enable PID
29: External trip
33: Disable additional freq setpoint
99: Enable BICO parameterization
Digital input 1 (DI1)
P0702 = …
Digital input 2 (DI2)
P0703 = …
Digital input 3 (DI3)
P0704 = …
If you enable one of the digital inputs to be freely used for BICO technology (P701…P704 =
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.
