Teaching pendant of an electromechanical system

A teaching pendant, connected to an emergency stop loop of electromechanical equipment, comprising:

• a multi-stage key switch comprising a first mode and a second mode, and being used to switch between said first mode and said second mode, said multi-stage key switch generating a switching signal when switching;
• an enabling switch connecting to said emergency stop loop of the electromechanical equipment;
• and
• a safety control device connected to said multi-stage key switch and used to receive said switching signal of said multi-stage key switch, said safety control device comprising a transient emergency stop circuit and a disconnection loop time, said transient emergency stop circuit connecting said emergency stop loop of the electromechanical equipment, said safety control device triggering said emergency stop loop to enter an emergency stop state according to said switching signal, during said emergency stop state said transient emergency stop circuit interrupts said emergency stop loop of the electromechanical equipment until the disconnection loop time is completed.
