PLS Sign & Graphics has been in partnership with Regina Tent & Awning since 1990. We offer awnings, canopies, applications of industrial fabric, and architectural signs.

PLS Sign and Graphic is here to help you prepare and ensure your business or workplace is safe for you customers, employees and staff. We manufacture sneeze guards, signs and decals to help everyone comply with public health recommendations. All products can be custom made to whatever size best fits your needs.

PLS Sign & Graphic was founded in 1987. Originally starting as just an agent for national sign manufacturers, it soon became apparent that the signs could be manufactured locally at a fraction of the cost, passing savings on to the client and improving quality.

In math, the plus-minus symbol (±) has several uses, depending on the context: Indicating both positive and negative solutions: When the plus-minus symbol is used in equations or expressions, it represents both the positive and negative solutions for a given value. For example:

脉冲信号，是指外部控制器如PLC输出口信号线连接到伺服驱动器的puls sign口。 puls是脉冲，而sign是用来控制伺服 电机正反转 用的。 例如：PLC输出口Y0，ON时伺服电机正传，当想要反转是Y2必须也要ON，也就是说伺服电机正传时Y0 ON，反转Y0，Y2都要ON。

伺服或者步进电机控制器的输入信号端子，当plc或者其他上位机发出脉冲信号进入puls端，这时电机正转，如果控制器设定的接受形式是“脉冲+方向”，则如果将sign加入低电平，电机就会反转（puls的信号不能断）。

The plus–minus sign or plus-or-minus sign (±) and the complementary minus-or-plus sign (∓) are symbols with broadly similar multiple meanings. In mathematics, the ± sign generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction.

2017年1月12日 · 机型FP0R，使用指令F171（梯形控制），控制方式是绝对值控制，如何实现正反转切换？ 1）修改控制代码。 PLS+SIGN（正转OFF/反转ON）时为正转，那么改变模式为绝对值控制PLS+SIGN（正转ON/反转OFF）即切换为反向运行。 2）修改目标值。 当目标值>当前值时电机正向运转，当目标值<当前值时电机反向运转>。 没有找到解答？
