The244 HARDWARE REFERENCE INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION
free-axis-displacement commands "L+" and "L-" are sent with the "lim+" and"lim-" arguments, respectively.There is no fixed hardware signal for a home switch on the Phytron controller, butthere are twelve digital inputs available on the input connector. There is also a commandwhich will perform a relative move at the base rate until one of the inputs goeshigh or low or the magnitude of the move is reached. There are four parameters inthis command: the direction of the move, the magnitude of the move, the binaryinput number and the sense of the input switch. All four parameters are set byentering a string as generic parameter 1 on the optional motor parameter screen ofthe configuration editor. (Get there by typing m twice from the standard motorparameter screen.) The string you enter will be sent to the motor when the "home"argument is used with the "chg_dial()" function. The string is the actual commandsent to the Phytron, and is of the formSmag vE nn Dwhere S is a + or a − for the sign of the move, mag is the magnitude of the move (maximumof 65535 steps), nn is the input number (01 through 12) and D is the sense of theinput where 0 means the motor stops if the input goes off and 1 means the motorstops if the input goes on. For example,+200vE071would command the motor to move no more than 200 steps in the plus direction, oruntil input 7 goes ON.Use the m command twice from the motor screen of the configuration editor to reachthe screen where you can enter generic parameter 1. Type an initial single quote toenter a string.Special CommandsOn faster computers, the Phytron apparently cannot keep up with commands sent bythe computer at full speed. Youcan slow down the communication between spec andthe Phytron controllers with the following commands:motor_par(motor, "rdelay" [, value]) — If value is given, sets the delay beforereading a response from the Phytron to value seconds, otherwise returns thecurrent value. The default value is 0.015.motor_par(motor, "wdelay" [, value]) — If value is given, sets the delay beforesending a command to the Phytron to value seconds, otherwise returns thecurrent value. The default value is 0.015.INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION HARDWARE REFERENCE 245
