3.6.2.5 Digital Input Signals
Control signal terminals 2, 3, 4, 6 and 10 all have the same function and
mode of operation as digital inputs (DI1 to DI5).
A logic level of +24 V (positive logic) is used:
• 8 - +30 V = High (logic "1")
• 0 - +4 V = Low (logic "0")
• Input current:
~ 4mA
• Signal common 0 V (control signal terminal 7 or 9)
The internal control voltage from control signal terminal 1 (+24 V) or an
external voltage source (+24 V) can be used for this.
By default (with the unit as supplied), the control signal terminals for the
digital input signals will be assigned as follows:
• Control signal terminal 2 as digital input 1 (DI1) = FWD (clockwise
rotating field enable signal)
• Control signal terminal 3 as digital input 2 (DI2) = REV (counterclockwise
rotating field enable signal)
• Control signal terminal 4 as digital input 3 (DI3) = Used to switch from
f-Set to fixed frequency (f-Fix1, f-Fix2)
• Control signal terminal 6 as analog input 1 (AI1) = f-Set analog setpoint
• Control signal terminal 10 as digital input 5 (DI5), can be switched
between f-Fix1 and f-Fix2.

￫
The setting (digital/analog) for terminals 6 and 10 will be
configured automatically based on the value set for P1-13.
