This parameter specifies the Pulse Reference input format.
0 - Digital Reference signals treated as Frequency and Direction.
1 - Digital Reference signals treated as Quadrature A & B signals.
2 - Digital Reference signals treated as Directional pulse input signals.
When using the pulse input, analog input cannot be used.
This parameter specifies the number of pulses per revolution for the selected Pulse reference input.
These two parameters display the 32-Bit reference position accumulator, accumulated with the input pulse
Slave Speed / Demand Ratio
Four parameters allow the user to specify the required ratio for the slave axis. These parameters are grouped in two banks (Bank 0 and Bank
1), allowing to switch in between the banks with a bit parameter. Each Bank is comprised of a numerator and denominator. The sampled
pulse counts every 250
µ
s are multiplied by the corresponding numerator and divided by the corresponding denominator to obtain the
required ratio of Speed / Position of the slave following the pulse reference input.
