XPS-Q8 Controller

example, if a driver and positioner respond to a constant voltage by moving at a
constant speed, then feed forward input would be dictated by the SetpointSpeed.
The XPS stores standard Newport stage configuration files that can be used to quickly
and easily develop the stage and system initialization (.ini) files. Below is an example of
a typical stage and the type of DriverName, MotorDriverInterface and CorrectorType
each is assigned. These standard Newport settings will be optimal for virtually every
application and users would only need to modify their corrector loop parameters (Kp,
Kd, Ki) to optimize positioner performance. Similar configurations can be adopted for
non-Newport stages that are of similar motor driver types.
Stages with high current (> 3 A) DC motor (RV, IMS) (with tachometer or back-emf
estimation):
DriverName: XPS-DRV01, 03
±10 V Input gives ±ScalingVelocity (stage velocity).
Speed loop & Current loop configured by hardware.
MotorDriverInterface: AnalogVelocity
CorrectorType: PIDFFVelocity for Speed loop and PIDFFAcceleration for current
loop.
Stages with DC motor driven through a current loop (RGV) (no tachometer):
DriverName: XPS-DRV02
±10 V Input gives ±ScalingAcceleration (stage acceleration).
Current loop configured by hardware.
MotorDriverInterface: AnalogAcceleration
CorrectorType: PIDFFAcceleration
Stages with low current (< 3 A) DC motor & tachometer (VP):
DriverName: XPS-DRV01 in velocity mode.
Input 1: ±10 V results in ±ScalingVelocity (theoretical stage velocity).
Input 2: ±10 V results in ±ScalingCurrent (3 A).
Speed loop programmable.
MotorDriverInterface: AnalogVelocity
CorrectorType: PIDFFVelocity
Stages with low current (<3 A) DC motor, without tachometer (ILSCC type):
DriverName: XPS-DRV01 in voltage mode.
Input 1: ±10 V results in ±ScalingVoltage (48 V).
Input 2: ±10 V results in ±ScalingCurrent (3 A).
MotorDriverInterface: AnalogVoltage
CorrectorType: PIDDualFFVoltage
Stages with Stepper motor & Encoder (UTSPP, RVPE, ILSPP...):
DriverName: XPS-DRV01 in stepper mode.
Input 1: ±10 V results in ±ScalingCurrent in motor winding 1.
Input 2: ±10 V results in ±ScalingCurrent in motor winding 2.
MotorDriverInterface: AnalogStepperPosition
CorrectorType: PIPosition
Stages with Stepper motor & no encoder (TRA, SR50PP, PR50PP, MFAPP):
DriverName: XPS-DRV01 in stepper mode.
Input 1: ±10 V results in ±ScalingCurrent in motor winding 1.
Input 2: ±10 V results in ±ScalingCurrent in motor winding 2.
