The maximum operating frequency of the counter in the PLC ladder program is limited by the scan period and is generally only a few tens of Hz. In industrial control, the PLC is sometimes required to have a fast counting function, and the counting pulse may come from a rotary encoder, a mechanical switch or […]

(1) When restarting, it will trip at a raise speed. This is a very serious phenomenon of overcurrent. The main reasons are: load short circuit, mechanical parts stuck; inverter module damage; motor torque is too small and so on. (2) Power-on jump, this phenomenon can not be reset generally, the main reasons are: bad module, […]

What kinds of sensors are classified by output parameters? (1) Resistive type This type of sensor is a change that will be measured by a sensitive component to a resistance. For example, platinum resistance, copper resistance temperature sensor, is the change of the measured temperature into the resistance value; the thermistor is also the change […]
