有谁会用吗??
我想用OMRON PLC CMP℃A来control DC motor speed.
用PLC 本身内的 PWM module.
有谁懂得用 ladder logic 吗??
Variations:
Differentiated variant available.
Purpose:
PWM(--) is used to output pulses with the specified duty ratio from port 1 or 2. The output can be set to one of three frequencies: 5.9 kHz, 1.5 kHz, or 91.6 Hz. The pulse output continues until INI(--) is executed to stop it.
In order for PWM(--) to be executed, the specified port must be set for variable duty ratio pulse outputs in the PC Setup. Set the leftmost digit of DM 6643 to 1 to enable variable duty ratio pulse output from port 1, and set the leftmost digit of DM 6644 to 1 to enable variable duty ratio pulse output from port 2. It is not possible to output normal pulses from a port that is set for variable duty ratio output.
Operand Data Areas:
P: Port specifier 001 or 002
F: Frequency 000 to 002
D: Duty ratio IO, AR, DM, HR, TC, LR, #
Availability:
CPM2*, CPM2*-S*, CQM1 (CPU4x only) and CQM1H.

讲什么??
不清不楚~~
用PC control moto speed对不对? |

不是啦。 PLC 是 Programmable Logic Controller. 它的 PROGRAMMING 是用 Ladder Logic 来做的。
看来这里是没人懂了

oh~~~
FPGA ar~~~
我以为altera, xillin, lattice 才有
想不到OMRON都有 |

你误会了, PLC是工业用的hardware Controller, 不是IC 。
PLC我基本上已经100%淘汰它了, 工业用的PLC,也渐渐走向PC base了,基于价钱和功能的考量。
要(玩)control motor , 可以用PIC16F628A 的PWM。 |
