Requirements of the encoder
•
Encoder signal: Rectangular with amplitude of 0.5-5 V or sine/cosine signal with 1VSS.
•
Encoder frequency
≤
≤ ≤
≤
300KHz
•
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 generated synthetically
Fundamental
•
The monitoring of the Standstill on zero is not possible.
•
The monitored standstil frequency is 5Hz after the divisor with Encoder measurement messsystem. With resolver
measurement messsystem the change of the phase is monitored.
•
With Encoder select a large relationship mode2/ Standstill as possible: With axis 10 to 20, with spindles 20 to 50.
•
The divisor with mode 2 is if possible > 10.
•
With (mode 1/ mode 2)>(1250Hz/ mode 2-Freq) requires divisor variable
•
With divisor variable the divisor with mode 2 must be
≤ ≤ ≤ ≤
2(31+1) or
≤ ≤ ≤ ≤
4(31+1).
Monitoring not used
If less than 8 actuations should be monitored the not used monitoring modules must be removed from the unit and
replaced by a bridge circuit connector.
Bridge Circuit connectors can be ordered from DINA.
Disable monitoring
If one monitoring system should be disabled, this could be done by connecting the input IN2 to 24V.
Faults and Errors
•
LED “SPEED” and “STOP” on the input and output modules do not light:
- The encoder is not connected.
- A proximity sensor failure.
•
LED “SPEED” and “STOP” on the monitoring module flash in 1 Hz intervals:
- Track A or B of encoder is missing.
- Proximity sensor at IN1 or IN2 is defective.
•
LED “SPEED” dos not light
- Registration of last crossing of the adjusted maximum speed.
To clear a fault the supply voltage must be switched off for at least 2s to reset the equipment (disconnect A1).
•
LED “STOP” and LED “SPEED” on the monitoring module flash in 2 Hz intervals:
- DNDS internal error.
- Error by improperly installed external signal lines.
The fault can possibly be eliminated by interruption of A1 for at least 2s.
