Hi,
I'm a new engineer working on a prototype with a circuit including the following components:
PLC (24V)
Servo Motor (separate channel, 5V)
Push Button ,fed by the same 24V and fed to the PLC.
I've written a very basic code, where I want the servo to perform a certain pattern of movement following the input from the button. The problem is that when I connect the grounds to each other, the channel that feeds the PLC spikes to nearly 50V. On the other, when the grounds aren't connected the input gate of the PLC always reads "HIGH", even if the wire connected to it isn't connected to any circuit at all!
Am I making a common mistake with a simple solution?
Oh and another bit of information, I've been burning through these servos like mad! I have no idea my the voltage/current are spiking like this.
Thanks to anyone who can give me any tips!
