Two-, and Three-Channel Stepper Motor Controller
The trigger settings can be used to configure multiple units in a master - slave set up,
thereby allowing multiple channels of motion to be synchronized. Multiple moves can
then be initiated via a single software or hardware trigger command.
Mode
The Mode parameter sets the trigger mode for the associated channel.
Disabled - triggering operation is disabled
Trig In - a move (specified using the Move Type parameter below) is initiated on the
specified channel when a trigger input signal (i.e. rising edge) is received on the Trig
In pin of the rear panel CONTROL IO D-type connector - see Section A.1. for pin out
details.
Trig In/Out - As for Trig In, but now a trigg er output signal will also be generated on
the Trig Output pin when the move begins - see Section A.1. for pin out details.
Trig Out - A trigg er output signal is generated on the Trig Out pin when a move
(relative, absolute or home) is initiated via software (either through the GUI panel or
ActiveX method call).
Move Type
The Move Type parameter determines the type of move to be initiated on the
associated channel when a trigger input signal is detected on the Trig In or Trig Out
connector.
Relative - trig gered relative mo ve. Relative move distance and ve locity profile
parameters can be set prior to trigge ring using the SetRelMoveDist and
SetVelParams methods respectively.
Absolute - triggered absolute move. Absolute move position and velo city profile
parameters can be set prior to triggering using the SetAbsMovePos and
SetVelParams methods respectively.
Home - triggered home sequence. Homing parameters can be set prior to triggering
using the SetHomeParams method.
