The nw_esp301 module

Module for Newport ESP301 motion controllers.

API

cmd_nw_esp301.init_nw_esp301(nw_esp301_id, conf_string)

Initialize NW_ESP301 motion controller.

conf_string must contain:

• bus: conf_string of the underlying link module
• chan: 1, 2 or 3 for the channel of the axis

cmd_nw_esp301.deinit_nw_esp301(nw_esp301_id)

Deinitialize and deregister nw_esp301 motion controller from the pool.

cmd_nw_esp301.config_nw_esp301(nw_esp301_id, pos_max, pos_min)

Configure nw_esp301_id axis. pos_max and pos_min define the limits of excursion.

cmd_nw_esp301.inval_nw_esp301(nw_esp301_id)

Invalidate nw_esp301_id configuration

cmd_nw_esp301.home_nw_esp301(nw_esp301_id, direction, velocity)

Reset axis nw_esp301_id by homing on direction at velocity.

cmd_nw_esp301.reset_nw_esp301(nw_esp301_id)

Reset the controller of nw_esp301_id, not just the axis

cmd_nw_esp301.go_min_nw_esp301(nw_esp301_id, velocity, acceleration)

Go to the minimum position as defined during the initalization of the axis

cmd_nw_esp301.go_max_nw_esp301(nw_esp301_id, velocity, acceleration)

Go to the maximum position as defined during the initalization of the axis

cmd_nw_esp301.move_nw_esp301(nw_esp301_id, displacement, velocity, acceleration)

Move by displacement units with the specified maximum velocity

cmd_nw_esp301.get_pos_nw_esp301(nw_esp301_id)

Get position of the specified axis

cmd_nw_esp301.get_pos(nw_esp301)

Get position of the specified axis

cmd_nw_esp301.get_error_queue_nw_esp301(nw_esp301_id)

Read error queue until the end (code 0)

cmd_nw_esp301.get_error_queue(nw_esp301)

Read error queue until the end (code 0)
