Constants

Defines some Enumerations for constant values

class pmac_motorhome.constants.ControllerType(value)

Defines the types of controller supported

brick = 'GeoBrick'

Geobrick controller

pmac = 'PMAC'

VME PMAC Controller

pbrick = 'PowerBrick'

Power pmac controller

class pmac_motorhome.constants.PostHomeMove(value)

Defines the set up actions available upon completion of the homing sequence

none = 'None'

no action

move_and_hmz = 'z'

move jdist counts away from the home mark and set that as home

relative_move = 'r'

move jdist counts away from the home mark

initial_position = 'i'

return to the original position before the homing sequence

high_limit = 'h'

jog to the high limit

low_limit = 'l'

jog to the low limit

hard_hi_limit = 'H'

jog to the high limit, ignorning soft limits

hard_lo_limit = 'L'

jog to the low limit, ignorning soft limits

move_absolute = 'a'

jog to the absolute position in counts

class pmac_motorhome.constants.HomingState(value)

Defines the stages of homing as reported back to the monitoring IOC TODO docs for this are incorrect and I’m confusing HomingState with HomingStatus

StateIdle = 0

Homing is not running

StateConfiguring = 1

Homing is starting up

StateMoveNeg = 2

Homing is moving in opposite direction to homing direction

StateMovePos = 3

Homing is moving in the homing direction

StateHoming = 4

HM command has been issued to the pmac

StatePostHomeMove = 5

executing any post home moves

StateAligning = 6

executing alignment (unused)

StateDone = 7

Homing is complete

StateFastSearch = 8

Pre Home fast search for home position

StateFastRetrace = 9

Moving back to just before home position

StatePreHomeMove = 10
