Operating Instructions ACU
Output value drops at set ramp
Output value is reset to initial value
0 = Contact open 1 = Contact closed
16.4.10 Handshake Traverse Function
Via Parameter Handshake Traverse Function 49 the signal source is selected for specification of the
direction of rotation of the slave drive of the traverse function. The Traverse Function is switched on
via parameter Operation Mode 435.
16.4.11 User Warning
For parameterization of external warnings, you can use parameters User Warnig 1 1363 and User
Warnig 2 1364 . Parameterization of an a user warning error enables triggering a warning in the
device via a digital signal in the event of a critical state. This warning is displayed in Application
Warnings 273 can be transmitted to a higher-level control. Please also refer to parameter Create
Appl. Warning Mask 626 and the explanations in Chapter "".
2 independent warnings can be parameterized via User Warnig 1 1363 and User Warnig 1 1364.
16.4.12 External Error
Parameterization of an external error enables switching off or shutting down several frequency
inverters at a time if a fault occurs in the plant or the drive. If an error occurs in a frequency inverter,
the error signal can be transmitted via a bus system and the required reaction can be triggered in
another frequency inverter. Parameter External Error 183 can be assigned the logic signal or digital
input signal which is to trigger the external error.
Via Parameter Op Mode ext. Error 535 the response to an external error can be configured.
No response to external errors.
The drive is switched off and the error message „F1454 External Error“ is
output if the logic signal or digital input signal for parameter External
Error 183 is present.
The drive is stopped at the current deceleration ramp and the error
message „F1454 External Error“ is output if the logic signal or digital
input signal for parameter External Error 183 is present.
The drive is stopped at the current emergency stop ramp and the error
message „F1454 External Error“ is output if the logic signal or digital
input signal for parameter External Error 183 is present.
For parameterization of external warnings, you can use parameters User Warnig 1 1363 and User
Warnig 2 1364 . Please refer to Chapter 16.3.9 "16.3.9" for more details.
16.5 Function Modules
16.5.1 Timer
The timer function can be linked to various functions for time-control of digital signals.
Parameters Operation Mode Timer 1 790 and Operation Mode Timer 2 793 define the evaluation
of the digital input signals and the unit of time of the time function.
Operation mode Timer 790,
793
Signal output is switched off.
Normal, Rising Edge, Sec.
Positive signal edge starts timer (trigger), time 1 delays the
output signal, time 2 defines the signal period
