Meaning
Momentary 15-bit setpoint:
0...32767 corresponds to an encoder revolution of 0...360° or 8192 output
pulses ( 4096, 2048 and 1024 can also be set on the SIMOLINK Encoder)
Unused
Momentary 15-bit setting value for the zero pulse:
Identical normalization to 'momentary setpoint'; absolute position of zero
pulse of SIMOLINK Encoder; transferred once when edge of bit 00
changes from 0 → 1.
Enabling of pulse outputs:
'SLE control' = 0
Pulse output by SIMOLINK Encoder is disabled
'SLE control' = edge change 0 → 1
Internal counters of SIMOLINK Encoder are loaded with reference values
(position of zero pulse)
'SLE control' = 1
Pulse output by SIMOLINK Encoder is enabled
