SureServo Drives and Motors Frequently Asked Questions
Question
How do you program the servo for positioning?
Answer
The servo drive can accept several positioning modes:- Position Control (external command)
Pt mode (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.
Position Control (internal command)
Pr mode (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 register) which can be absolute or incremental mode and each of them can be selected by 3 configured digital inputs. Set the parameter P1-01 as 1.
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 can also be changed. Application note AN-SERV-007 is one example of this.
Variations of these basic position modes can also be done, with reduced features. More information is in chapter 5 of the SureServo User Manual
