Pulse Output Function Details

Overview

Pulses are output in independent mode or continuous mode. In independent

 

 

mode, the number of output pulses is specified in advance. In continuous

 

 

mode, the number of output pulses is not specified in advance.

 

 

 

 

 

 

Mode

Description

 

 

 

 

 

 

Independent mode

This mode is used for positioning.

 

 

 

The pulse output stops automatically after the specified num-

 

 

 

ber of pulses has been output. With some instructions, the

 

 

 

pulse output can be stopped (see note).

 

 

 

 

 

 

Continuous mode

This mode is used for speed control.

 

 

 

The pulse output continues until it is stopped by an instruction

 

 

 

(see note) or the Motion Control Module is switched to PRO-

 

 

 

GRAM mode.

 

 

 

 

Note When pulses are being output by an SPED(885) or ACC(888) instruction, the pulse output can be stopped by executing the INI(880) instruction. The pulse output can also be stopped by executing SPED(885) or ACC(888) with a tar- get frequency = 0.

When pulses are being output by the PULS(886) instruction (Electronic Cam Control), the pulse output can be stopped by executing the INI(880) instruc- tion.

When using independent mode, select one of the four pulse output operation modes shown in the following table, depending on the method used to calcu- late the number of pulses and whether it is necessary to change the value during operation. Specify the pulse output operation mode in the System Setup (the operation mode setting in the Pulse Output Tab Page). In addition, if the PULS(886) instruction is being used, it is necessary to specify the Pulse Type in the second operand.
