Newport SMC100 motor controller¶

Bliss controller for Newport SMC100 motor controller.

The controller communicates via serial line. Baudrate (57600) and terminator (CR/LF) are configured within the controller. Other parameters are default ones (data bits=8, parity=None).

Note

Only SMC100_CC controller has been tested. SMC100_PP also exist for stepper motors.

On controller restart, the axis is in NOTREFENCED state. A homing has to be performed before using it.

Supported features¶

Encoder	Shutter	Trajectories
No	No	No

Configuration¶

Note

By default, controller has address 1. Address is changed only if using multiple controller in a daisy chain.

Example:

controller:
  class: NewportSMC100
  module: newport
  serial:
    url: tango://id00/serial_001/1
  axes:
    - name: smc1
      steps_per_unit: 1
      velocity: 25.0
      acceleration: 100.0
      tolerance: 0.001
      address: 1

Specific methods¶

Get a detailed status from controller:

NEWPORT [6]: smc1.read_status()
CONTROLLER STATE : READY from DISABLE
CONTROLLER ERRORS : NONE.
BLISS AXIS STATE :
  READY (Axis is READY)

Read stage identification:

NEWPORT [7]: smc1.read_stage()
STAGE : VP-25XA_PN:B147328_UD:142410

Read hardware configured limits:

NEWPORT [8]:
NEWPORT [8]: smc1.read_limits()
    Out [8]: ('-12.5', '12.5')

These limits can be set to bliss software limits using smc1.configure_limits().

Read hardware specific parameters:

NEWPORT [10]: smc1.read_parameters()
    Out [10]: {'low_pass_filter': '1000', 'following_error': '0.1', 'friction_compensation': '0', 'jerk_time': '0.04', 'derivative_gain': '1.99951', 'integral_gain': '12487.8', 'proportionnal_gain': '498.047', 'velocity_feed_forward': '0.541992'}

To change this parameters, use:

NEWPORT [11]: c = smc1.read_parameters()
NEWPORT [12]: c["integral_gain"] = 12487.8+1
NEWPORT [13]: smc1.write_parameters(c)
Go to DISABLED state
Set integral_gain = 12488.8
Go to READY state
NEWPORT [14]:

The method smc1.configure_stage() can be used to upload configuration from an ESP stage. This should not be needed as an ESP upload is performed on controller reset.

To Reset controller, use smc1.reset_controller().
