Reaction times
The total reaction time is the sum of:
• Reaction time of the motion monitor
• De-energisation time of the output relay (<20ms).
• Delay of de-energisation on any external switching devices.
The reaction time of the motion monitor decreases as the speed to be monitored increases (linear).
It measures at 5 Hz about 200 ms and at 800 Hz about 1 ms

DNDS 1C, 1FA, 2C, 2FA: Applications of the outputs
STOP contacts: Standstill monitoring
If the protection cover is closed and one or more drives are in movement, the NO-contacts 13-14 open immediate-
ly. The NC-contacts 11-12 close. The LED STOP is not illuminated. The protection cover cannot be opened.
If all drives are stopped the contacts 13-14 close and 11-12 close. The protection cover can be opened. The LED
STOP is illuminated.
SPEED contacts: Motion monitoring
If the protection cover is closed, the F-inputs and
respectively the D-inputs of DNDS will be connected
to 24V DC via the switch of the protection cover. The
automatic mode will be monitored.
In case of the protection cover is open DNDS moni-
tors the standstill of all drives, if there is no function
mode selected.
If there is some function mode selected, as example
tool setting via SH-, R-input of DNDS, this function
mode will be monitored.
If one or more drives break the standstill as well as
the adjusted speed of the function mode, the NO
contacts 23-24 open and 21-22 close immediately.
The LED SPEED does not illuminated.
The drives will be stopped by emergency stop circuit
(STOP category 0). See principal schematic.
The contacts 23-24 close and 21-22 open again, if
the actual speed is 10% lower than the adjusted
speed. The LED SPEED illuminates.

Function description: DNDS 1C, 1D, 1FA & 1GA
DNDS 1C, 1D, 1FA & 1GA:
The DNDS acts as a failsafe monitor of a rotary respectively linear motion and standstill. The speed monitor shut-
down trigger point can be programmed via 4 inputs (D1–D4). This shutdown trigger point can be further modified
from 100% down to 5 % via the 4inputs (F1–F4)
DNDS 1C, 1D has an internal (R) input to switch between constant and variable creep velocity (see table 1 and 2).
The motion detection can be monitored via 2 PNP-proximity sensors or a rotary encoder.
If PNP-proximity sensors are used, attention must be paid to mount them in a way, so always one of the two sen-
sors is activated.
Rotary encoders can only be connected using a DNIA adaptor (for the rotary encoder specifications, see the DNIA
operating instructions).
DNDS 1FA, 1GA has an external (R) input to switch between constant and variable creep velocity. A further exter-
nal (SH) input is used for switching over between creep velocity and standstill (see table 1 and 2).
For motion monitoring a rotary encoder is required. The Rotary encoder is connected via a DNDA 15/8 or DNDA
25/8 adaptor to the DNDS 1FA, 1GA
Function of the inputs of DNDS 1C, 1D, 1FA & 1GA
D-inputs:
- Setting the automatic operation mode speed in 16 steps (00-15 = 100 – 800 Hz, table 1)
- D-inputs are only of importance if at least one F-input is connected to 24V
- If the F-inputs are not active (open) and the R-input is active, the active D-inputs determine the value of the tool
setting speed.
F-inputs:
- F-inputs reduce the stting value via the D-inputs in 15 steps, 01-15 = 25-100%.
- The F-inputs are also a switch over between tool setting (all F= open) and automatic operation mode (any F con-
nected with 24V). The tool setting speed is variable between 1-20 Hz or constant 5 Hz.
- The F-inputs setting is store internally to determine the tool setting speed, if all F inputs are switched off. The
stored F setting is valid until the equipment is powered off.
- The value of the tool setting speed is determined by the stored F-inputs, if the D-inputs are open and the R-input
is active.
R-input:
- R-input works only if the F-inputs are switched off (open).
- If the R- and D-inputs are active the creep rate is determined by the active D-inputs. (see Table 1)
- If the D-inputs are open the tool setting speed is determined by the stored F setting .
- If the R-input and the Finputs are not active, the standstill is monitored.
- R- and SH inputs must not be connected to 24V at the same time.
SH-input: DNDS 1FA, 1GA only
- The SH input is used to switch between tool setting speed and standstill (50Hz and 5Hz)
- The SH-input works only if the R-input and all F-inputs are switched off (open).
- If the SH-input and the F-inputs are open the standstill will be monitored.
- If the SH-input is active (SH connected to 24V) and the F-inputs are open the tool setting speed will be moni-
tored.

Reaction times
The total reaction time is the sum of:
• Reaction time of the motion monitor
• De-energisation time of the output relay (<20ms).
• Delay of de-energisation on any external switching devices.
The reaction time of the motion monitor decreases as the speed to be monitored increases (linear).
It measures at 5 Hz about 200 ms and at 800 Hz about 1 ms
Installation of DNDS 1C, 1D, 1EA, 1GA
• The equipment must be cabinet mounted min. IP 54). The Equipment is equipped with a latch for DIN-rail at-
tachment.
• Supply operating voltage of 24V to terminals A1 (+) and A2 (-). Connect button (reset fault memory) to terminal
A2.
• Input circuit: DNDS 1C, 1D
- Proximity sensor (PNP):
Connect output of the first proximity sensor to IN1 and the 2nd to IN2. Both proximity sensors should be con-
nected to supply voltage A1 and A2.
- Encoder with DNIA adaptor:
Connect output IA1 of the DNIA to terminal IN1; connect output IA2 of the DNIA to terminal IN2; A1 of both
units should be connected together.
• Programming
- rpm setting: Connect 24 VDC to the terminals D1-D4 according to desired rpm (see table 1).
- Reduction in %: Connect 24 VDC to the terminals F1-F4 according to table 2.
• Input circuit: DNDS 1FA, 1GA
- Connect the Equipment by using a DNDA 15/8 or DNDA 25/8 adapter cable to the encoder.
Please note for operation
• To prevent a welding together of the contacts, a fuse (6 A slow acting) must be connected before the output
contacts.
• The total of the reaction times must not lead to a dangerous status.
• Use copper wiring that will withstand 60/75°C.
• Tighten screws to terminals with 0.8 Nm max.
• Important details in the section “Technical Data” should be noted and adhered to.
Faults - Errors of DNDS 1C, 1D, 1FA, 1GA
• Welding of one contact makes it impossible for the other contact to be switched on.
• LED “SPEED” and “STOP” do not light:
A PNP proximity sensor failure.
PNP proximity sensor not connected.
PNP proximity sensor is not installed on the tooth wheel.
There is a line break to the DNIA.
The encoder is not connected.
• LED “SPEED” flashes with 1 Hz interval:
The peripheral equipment belonging to input IN2 is defective or there is a line break at that input, or Track A of
the encoder is missing.
• LED “STOP” flashes with 1 Hz interval:
The peripheral equipment belonging to input IN1 is defective or there is a line break at that input or Track B of
the encoder is missing.
To reset the error disconnect the operating voltage for at least 2s (disconnect A1)
• LED “STOP” and LED “SPEED” flashes in 2 Hz intervals:
R and SH connected to 24V simultaneously.
DNDS 1C disturbance.
Error by improperly installed external signal lines.
The fault can possibly be eliminated by interruption of the operating voltage for at least 2s (disconnect A1).

Function of DNDS 2C, 2D and 2GA
The DNDS 2C, 2D, 2GA includes 2 independent monitoring systems for failsafe monitoring of a rotary respectively
linear motion and standstill .
DNDS2 C, 2D:
The machine rpm setting is done by 3 programmable inputs for each system.
The motion detection can be monitored by 2 PNP proximity sensors or one encoder per monitoring system. If PNP-
proximity sensors are used, attention must be paid to mount them in a way, so always one of the two sensors is
activated.
Rotary encoders can only be connected using a DNIA adaptor (for the rotary encoder specifications, see the DNIA
operating instructions).
DNDS 2GA:
The machine rpm setting is done by 4 programmable inputs for each systems.
Each system uses its own encoder to monitor the motion. The encoder can only be connected using a DNDA 15/8
or 25/8 adaptor (for specifications of the rotary encoder, see the impulse diagram)
Function of the inputs of DNDS2 C, 2D
D-inputs:
- Position 0-7 (T1), DNDS 2C, 2D
- Position 0-15 (T2), DNDS 2GA
- The D-inputs are a switch over between tool setting (D= open) and automatic operation mode (D connected with
24V).
SH-input: DNDS 2GA only
- If the SH-input and the D-inputs are open standstill will be monitored.
- After the D-inputs are switched off it can be switched over between tool setting speed (SH connected to 24V)
and standstill (SH open).
