SPEED OUTPUT: SPED(885)

Transcription

1 Two target values High-speed counter input 0 Register target comparison table and start comparison D101 D102 D103 01F Target value 1: 01F4 hex (500) Incrementing, Interrupt task number 1 D104 D105 D106 03E Target value 2: 03E8 hex (1000) Incrementing, Interrupt task number SPEED OUTPUT: Purpose is used to set the for a specific port and start without acceleration or deceleration. Either independent mode positioning or continuous mode speed control is possible. For independent mode positioning, the number of s is set using. can also be executed during to change the, creating stepwise changes in the speed.

3 Upper Limits to the Target Frequency Description Port CP1H CP1L X40/XA40 version 1.0 X40/XA40 version 1.1 or higher starts on the port specified in P using the method specified in M at the specified in F. Pulse will be started each time is executed. It is thus normally sufficient to use the differentiated version (@) of the instruction or an execution condition that is turned ON only for one scan. Y20 Port khz 100 khz 1 MHz 100 khz Port khz 100 khz 1 MHz 100 khz Port 2 30 khz 100 khz 100 khz --- Port 3 30 khz 100 khz 100 khz --- Target executed. In independent mode, will automatically when the number of s set with in advance have been. In continuous mode, will continue until ped from the program. An error will occur if the mode is changed between independent and continuous mode while s are being. Continuous Mode Speed Control When continuous mode operation is started, will be continued until it is ped from the program. Note Pulse will immediately if the CPU Unit is changed to PROGRAM mode. Operation Purpose Application Frequency changes Description Procedure/ instruction Starting To with specified speed the speed () in one step Target Outputs s at a specified. settings To change speed in one step the speed during operation Target Changes the (higher or lower) of the in one step. 725

4 Operation Purpose Application Frequency changes Description Procedure/ instruction Stopping Stop Stops the immediately. Stop Stops the immediately. (Continuous, Target of 0 Hz) Independent Mode Positioning When independent mode operation is started, will be continued until the specified number of s has been. Note (1) Pulse will immediately if the CPU Unit is changed to PRO- GRAM mode. (2) The number of s must be set each time is restarted. (3) The number of s must be set in advance with PULS(881). Pulses will not be for if PULS(881) is not executed first. 726

Operation Purpose Application Frequency changes Description Procedure/ instruction Starting settings To with specified speed To change speed in one step Positioning without acceleration or deceleration the speed in one step during operation Target Pulse New target Original target Specified number of s (Specified with.) Outputs the specified number of s and then s. Specified number of s (Specified with Number of s.) specified with does not change. (independent mode) (independent mode) executed again to change the target. (The target position is not changed.) Starts ting s at the specified and s immediately when the specified number of s has been. Note The target position (specified number of s) cannot be changed during positioning. can be executed during positioning to change (raise or lower) the in one step. The target position (specified number of s) is not changed. Stopping To (Number of s setting is not preserved.) Present Stops the immediately and clears the number of s setting. PLS2(887) Stop (Number of s setting is not preserved.) Stops the immediately and clears the number of s setting., (Independent, Target of 0Hz) 727

6 Flags Example Name Label Operation Error Flag ER ON if the specified range for P, M, or F is exceeded. ON if PLS2(887) or ORG(889) is already being executed to control for the specified port. ON if or is used to change the mode between continuous and independent during. ON if is executed in an interrupt task when an instruction controlling is being executed in a cyclic task. ON if SPEC(885) is executed in independent mode with an absolute number of s and the origin has not been established. When CIO 0.00 turns ON in the following programming example, sets the number of s for 0. An absolute value of 5,000 s is set. is executed next to start using the CW/CCW method in the clockwise direction in independent mode at a target of 500 Hz. D Number of s: 5,000 D110 D111 01F4 Target : 500 #0001 D110 Target : 500 Hz 5,000 s PULS(881) and the executed SET PULSES: Purpose is used to set the amount (number of s) for s that are started later in the program using or ACC(888) in independent mode.
