Counter value reset
A recurring reset of the counter value in the process data “Counter value” (0x60n0:11) to “0” can be done in the following ways:
- Input zero pulse C: a positive edge at the zero pulse C input (“Enable C reset”)
- Latch input: an edge (positive/negative) at the “Latch extern” input (“Enable extern reset”)
The settings are made in the configuration data, so it is not necessary to reactivate the device after a reset.
It is not possible to activate the “Enable C reset” (Index 0x80n0:01) and “Enable extern reset” (Index 0x80n0:02) functions at the same time.
Counter value reset via the zero pulse C input (Enable C reset)
The counter value can be set to the value specified in index 0x80n1:1B “Reset counter value” for every full revolution of the encoder via the zero pulse C.
Counter value reset via the “Latch extern” input (Enable extern reset)
The counter value can be set to “0” via the “Latch extern” input.
- Setting the reset value via index 0x80n1:1B “Reset counter value” (default: 0)
- To activate this function set the bit in index 0x80n0:02 “Enable extern reset”.
- Index 0x80n0:10 “Extern reset polarity” can be used to specify at which edge the “Latch extern” input is active.
- 0: “Fall” - the counter is set to “0” with a negative edge
- 1: “Rise” - the counter is set to “0” with a positive edge
There is no status message via the process data.
