Installation and Start-up

1.7.4 Alarm Input

For a monitoring of the encoder to channel 1 and the encoder cable the signal tracks and the
zero track are monitored. If the connected encoder has no zero track, then the the 5V-supply
must be assigned to track N+ and COM to N- at the encoder plug. The monitoring for channel
1 will be switched on/off with parameter Ec.20 Bit 2.
The recognition of encoder breakage triggers an „error! Encoder 1" (value 32), if the voltage
between two signal pairs is smaller than 625mV.
