List of input signals
Signal name, description
Inactive
The input with this function is switched "inactive".
The input terminal can still be connected–up, but is not evaluated.
Application:
During commissioning (start–up), "disturbing" inputs are first disabled, and are then activated later and
commissioned.
Reset fault memory
Faults that are present that are acknowledged with RESET FAULT MEMORY, are reset via this input sig-
nal.
Before acknowledging faults/errors, their cause must first be removed.
Prerequisites:
The controller enable signal at terminal 65.x has been withdrawn.
1 signal
No effect
0/1 signal
The fault memory is reset and the fault(s) acknowledged using a 0/1 edge.
0 signal
No effect
Note:
S
Faults, which can be acknowledged with POWER ON, cannot be reset in this fashion.
S
The drive remains in the fault condition until all of the faults/errors have been removed.
In the PROFIBUS mode the system then goes into the "power–on inhibit" status.
S
From SW 6.1 onwards and for P1012.12=1, the fault can also be acknowledged without the prerequi-
site that the control signal STW1.0=0. The drive however, remains in the "power–on inhibit" condition.
Open–loop torque controlled mode
It is possible to toggle between closed–loop speed controlled and open–loop torque controlled operation
via this input signal.
1 signal
Open–loop torque controlled operation (M
0 signal

Application: Master/slave, refer to Chapter 6.6.5.
Motor data set changeover (from SW 2.4)

1st input/2
1
2nd input/2
It is possible to toggle between a total of 4 motors/motor data sets using these 2 input signals.

1st input/weighting 2

2nd input/weighting 2
Note:
S
The motor changeover version and therefore the behavior of the terminal, is selected using P1013
(motor changeover).
S
Output terminal signals with function numbers 11, 12, 13 and 14 (motors 1, 2, 3 or 4 selected) are
used to control the contactors to change over the motor.
S
In order to ensure that the function changes over in a controlled fashion (identified as being simulta-
neous) the switching operation of the inputs must be completed with one interpolation clock cycle
(P1010).
S
Motor changeover is described in Chapter 6.11.
