Product Information
Safety technics modular generation in metal housing version 08 dated: 2009-04-10 page 6 from 32
Features:
Dual channel motion and standstill monitoring.
Connection for an encoderto the RJ45 jack or 2 PNP-proximity sensors to IN1 and IN2
Status indicators.
Programmable speed setting
The DNDS complies with the safety requirements( see below)
The circuit is redundant with built-in self-monitoring.
The safety function remains effective in the case of a component failure.
Motion detection of machines
The motion detection of an actuation can be accomplished via an encoder, resolver or 2 PNP-proximity sensors. The encoder or
Resolver is connected via a cable adapter DNDA 15/8 or 25/8 to the DNDS.
For motion detection via 2 PNP proximity sensors the inputs IN1 and IN2 are used. When mounting the proximity sensors on a
tooth wheel, attention must be paid to mount them in a way, so always at least one of the two sensors is activated.
Function of the inputs
IN- inputs
:
IN1 and IN2 are used, if proximity sensors are used for speed monitoring. Two PNP switches are necessary.
By connecting IN2 constantly to 24V DC and IN1 left open, the monitoring module is forced into detecting solid standstill. In this
way the monitoring module is disabled from monitoring.
Inputs for function modes
Monitoring modules:
DNDS 1EG V9 and
DNDS 1RG V1
D- inputs
: 00–15, for setting of the automatic operation mode
(mode1).
D-inputs are only of importance if at least one F-input is connected to
24V.
F-inputs
: 01-15 for reduction of setting D-inputs setting from 100 to
25%. The F-inputs are a switch over between tool setting mode (mode
2) respectively semi-automatic mode (mode 3), “F are NC” and mode1.
At least one F- is connected to 24V.
R1-input
: for setting the mode 3
R1-input is only active, if F1-F4 are off.
SH-input:
for setting the mode 2
SH-input is only active, if R1 and F-inputs are NC.
Monitoring modules: DNDS 1EG V7A, DNDS 1EGV7C and
DNDS 1RG V2, DNDS 1RG V3C
M-
rather
MT-inputs:
These inputs can be used, if the automatic
mode (mode 1) has not to be monitored. Only D- or M- rather MT-
inputs can be used. The M- rather MT-inputs are a switch over be-
tween tool setting mode (mode 2) respectively semi-automatic mode
(mode3), “M, MT are NC” and mode1. M-, MT-inputs connected to
24V.
D- inputs
: D1-D6 = 0-63, for setting of mode 1. The D-inputs are a
switch over between mode 2 respectively mode 3 “D = are NC” and
mode 1. Any D-input connected to 24V.
R1-input
: for setting the mode 3
R1-input is only active, if D-, M- respectively MT-inputs are NC.
SH-input:
for setting the mode 2. SH-input is only active, if R1, D-, M-
respectively MT-inputs are NC.
