Functions
Main function of SID116 driver is control of drive operation with DC motor driver according to selected regulation
mode and control signal.
For each operation mode driver has independent memory of
16 settings
. Each setting consist in numerical value
and type which defines if setting is
absolute
or
relative
. Absolute setting after selection is assigned directly to
pulse generator input. Relative setting is assigned to driver input after sum with current value of pulse generator.
All settings are saved in non-violate memory.
Picture. 3. Block diagram
Activation of selected setting is made by indication of its index. Index can be selected by:
Modbus protocol
- after write its value to proper control register or using Jog command,
Driver input
:
o
Binary
– values of individual inputs are treated as next index bits,
o
Parallel
– input high state directly activate setting index assigned to it according to input priority,
PC application (USB)
.
Driver allows also direct control of set value based on selected control interface. Then each change on interface
input is transmitted to pulse generator input. User can use 4 control interfaces:
Analog input 0..10 V
Step/Dir
– depend on Dir input state each signal slope cause setting increase or decrease by 1,
Master encoder
– square wave signal value on input is assigned directly to set value,
AB
Pulse
– slope on A input cause increasing of set value by 1, slope on B input cause decreasing set
value by 1.
