Question How do you program the servo for positioning?
Answer The servo drive can accept several positioning modes: 5.1 Pt mode or position terminal mode, with pulse and direction high speed pulses, quadrature pulses or clockwise and counter clockwise high speed pulses.In this modem, the servo drive is just an amplifier and the control is done by the controller generating pulses, for example, a CNC controller or a PLC module that could generate a trapezoidal profile. Set the parameter P1-01 as 0. 5.2 Pr mode or position with registers mode. In this mode, you can store up to 8 target positions, defined by revolutions (in one parameter register) and counts (in a consecutive parameter regster) which can be absolute or incremental mode and each of them can be selected by 3 configured digital inputs. Additionally, you can send target set points though MODBUS communications from a Master that talks MODBUS at rate of up to 115.2 kBaud. Speeds, accelerations and decelerations coul also be changed One example can be found on the application note AN-SERV- 007. Variations of these basic postion modes can also be done, with reduced features. More information can be seen on the chapter 5 of the user manual, rev 2/2008.
