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).
