Description of DNDS 1C, 1D, 1FA, 1GA, 2C, 2D and 2GA
The DNDS is enclosed in a 100mm housing and requires a supply voltage of 24 VDC.
Features:
DNDS 1C, 2C & DNDS 1FA:
for standstill monitoring one safety contacts (13
for motion monitoring one safety contacts (23
DNDS 1D, 2D, DNDS 1GA & 2GA:
for standstill monitoring two safety contacts (13
for motion monitoring two safety contacts (33
DNDS 1C, 1D, DNDS 2C & 2D:
Connections for PNP-proximity sensors or an encoder via a DNIA adaptor.
DNDS 1FA, DNDS 1GA & 2GA:
The encoder is connected via a DNDA Cable adaptor type DNDA.
Status indicators.
Programmable machine rpm setting.
The DNDS complies with the following safety requirements:
The circuit is redundant with built-in self-monitoring.
•
The safety function remains effective in the case of a component failure.
•
With every on-off cycle of the machine the relays are automatically tested to make sure they open and close
•
correctly.
Signals of encoder
Requirements of the encoder
Encoder signal: Rectangular with amplitude of 0.5-5 V or si-
•
ne/cosine signal with 0.5-5 VSS.
Encoder frequenzy ≤ ≤ ≤ ≤ 300KHz TTL, 200KHz Sin/Cos.
•
Encoder with high resistance outputs during malfunction.
•
2 tracks 90° out of phase, 2 signals per track that are 180° out
•
of phase
The signals of encoder are not allowed to be generate syntheti-
•
cally
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
