Function of the DIP switches
S1 & S2 function, Position 1-9:
Setting of a
division factor ( ) for the encoder adaptation

S4 function:
Positions 1 & 2 on:
Speed output automatic restart disable.
If there is an overspeed, the output contacts SPEED of the output module switch-off and remain switched off also
during standstill. The contacts close again, if the power supply will be turned off
≥ ≥ ≥ ≥
2s .
This function is not possible with DNDS 1EG V7C with the item-no. 22EG36-01.
Positions 1 & 2 off: Speed output automatic restart enable.
If there is an overspeed, the output contacts SPEED of the output module switch-off. The contacts close again, if
the actual speed is 10% less than the adjusted speed.
This function is possible with all modules.
Positions 3 & 4 on:
The encoder operating voltage is supplied by the DNDS. Only allowed for DNDS with one or 2 monitoring modules.
Positions 5 & 6 off : Divisor ( ) is constant. Switched on positions 1 to 9 of S1, S2 are always active as a divisor.
Positions 5 & 6 on : Divisor ( ) is variable.
If the M-inputs respectively the MT-input or the D-inputs are not connected to 24V, the switched on positions 1 to 5
and position 9 of S1 and S2 are active as a divisor.
If the M-inputs respectively the MT-input or one rather more D-inputs are connected to 24V, all switched on posi-
tions 1 to 9 of S1 and S2 are active as a divisor.
Outputs of DNDS 1EG V7C
The modules DNDS 1EG V7C has two positive switching outputs O1 and O2. Normally the outputs are switched to
24V. The power supply for these outputs has to be connected to the terminal 24V at the module.
Output O1 switch off, if there is a sensors failure at the Encoder input or at IN1 or IN2.
O1 switch on again, if the reason for the switching off does not exist.
Output O2 switch off and the LED SPEED is not illuminated, if there is an overspeed, an external or an internal
failure, that causes a switch off of the outputs at the output modules.
O2 with overspeed and enabled speed output automatic restart:
O2 switch on again, if the actual speed is
≥
≥ ≥
≥
10% less than the selected speed. The LED SPEED is illuminated.
O2 with overspeed and disabled speed output automatic restart:
O2 remain switched off and the LED SPEED remain dark also during standstill of the drive. O2 switch on and the
LED SPEED illuminates again, if the power supply will be turned off
≥ ≥ ≥ ≥
2s .
The frequency values in Adjusting table are calculated as follows:
Table value = Encoder frequency (adjusted divisor at S1 and S2) + 1
