3.6.2.5 Digital input signals
116
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")
Typical input current: ~ 4 mA
•
• 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) = Switch-over from
f-setpoint to fixed frequency (f-Fix1, f-Fix2),
• Control signal terminal 6 as analog input 1 (AI1) = analog setpoint value
f-setpoint,
• Control signal terminal 10 as digital input 5 (DI5), switchable between
f-Fix1 and f-Fix2.
￫
The setting (digital/analog) for terminals 6 and 10 will be
configured automatically based on the function selection with
parameter P1-13.
