Functional DescriptionDigital In- and Outputs
6.3.15 Switching Conditions (do.0...do.7)
From the following switching conditions one can select up to 8 for further processing.
The values are then entered in the parameters do.0...do.7.
ValueFunction
0 Off
1 Always active
2 Run signal; also at DC-braking
3 Ready for operation; if no fault exists (ru.0 <> error)
4 Fault relay trips, when the inverter is switched off with an error
5 Fault relay, as at 2, but not for errors which are reset automatically with activated „Auto-restart-function“
6 Warning or error signal is given, when the inverter fulfills an abnormal-stopping condition (ru.0).
7 Overload-prewarning! ru.39 is an overload counter, counting in steps of 1%. On reaching 100 % the inverter
switches off. Upon exceeding the level of Pn.9 (default 80%) the overload warning is given. The performance in
case of a warning can be adjusted with Pn.8 (response to OL-warning)
8 Overheating-prewarning (OH)! Depending on the power circuit the inverter switches off between 60...95°C power
module temperature. The prewarning is output, when the level OH-warning (Pn.11) is reached (default 70°C). The
behaviour in case of an warning can be adjusted with Pn.10 (response to OH-warning).
9 PTC-prewarning (dOH), on tripping of the motor-PTC connected to the terminals T1/T2. After expiration of an
adjustable switch-off time Pn.13 (0...120s) the inverter switches off. the behaviour in case of an error can be
adjusted with Pn.12 (response to dOH-warning).
10 Motor protection prewarning (OH2), if the motor protection triggering time defined according to VDE has expired.
The response to the warning can be adjusted with Pn.14 (response to motor protective function)(see Chapter 6.7
„Motor protective function“).
11 Interior temperature-prewarning (OHI) is output, when the interior temperature of the inverter exceeds the level
OHI-warning (Pn.17). The behaviour in case of an error can be adjusted with Pn.16 (response to OHI-warning).
Not at Pn.16 = 7
12 Cable breakage at 4...20mA setpoint adjustment at AN1; Trips, if the setpoint current drops below 2mA (An.0 =
2).
13 Cable breakage at 4...20mA setpoint adjustment at AN2; Trips, if the setpoint current drops below 2mA (An.10 =
2).
14 Max. constant current (Stall) exceeded (Pn.17). See chapter 6.7 „Constant current limit“.
15 Ramp stop function active (LA-/LD-Stop), current (Pn.22) or voltage (Pn.23) exceeded during acceleration/
deceleration. See chapter 6.7 „Ramp stop“.
16 DC-braking active; see chapter 6.9 „DC-brake“
17 Power-Off function active (see chapter 6.9 „Power-Off“), in case of an error or SSF the condition is not fulfilled
18 Brake control is set, when the brake shall be released (see chapter 6.9 „Brake control“)
19 Speed control difference > level
20 Actual value = setpoint at constant run; not at ru.0 = noP, LS, Error or SSF.
21 Inverter is in the acceleration phase, at ru.0 = FAcc, rAcc and LAS (acceleration stop)
22 Inverter is in the deceleration phase, at ru.0 = Fdec, rdec and LDS (deceleration stop)
23 Actual direction of rotation = set direction of rotation
24 Utilization (ru.13) > level
25 Active current (ru.17) > level
26 DC-link voltage > level
27 Actual value (ru.7) > level
28 Setpoint value (ru.1) > level
29 Ref. point run completed (only F5-M/S)
30 Actual torque > level (only F5-M/S)
31 AN1 on output of characteristic amplifier > level; without sign evaluation
32 AN2 on output of characteristic amplifier > level; without sign evaluation
