Example for the required minimum speed with encoder mode
Encoder has 12.5 pulses per mm
1 Encoder pulse is 1/12.5 mm = 0.08 mm
V
min
= 0.08 mm/0.59 s = 0.135 mm/s
7.6.3
Encoder channels
Function
Enables the line trigger or encoder mode in the camera and the main
selection between internal and external line trigger.
Dependency
Only active with selected “Encoder mode” at the “Synchronization mode”.
Notes
For the use of this mode, the external ports have to be connected to the
internal function by using the IO-Configurator of CST.
One-Channel full step (1 edge per step)
Fig. 56: One-Channel full step, phase A and phase B
One-Channel encoder (2 edges per step)
Fig. 57: One-Channel encoder, phase A and phase B
Two-channel encoder (4 edges per step)
Fig. 58: Two-channel encoder, phase A and phase B
Best results will be reached with encoder mode 0 and without encoder averaging.
This mode will avoid errors due to tolerances in the duty factor of the pulses.
