What is the cause of insufficient displacement of Copeland compressor

Insufficient compressor displacement has a great impact on the entire refrigeration system. If it is not repaired and handled in time, it may cause problems such as the cylinder, cylinder head rupture, and compressor water intake, which will destroy the entire refrigeration system cycle. It may even cause accidents such as compressor combustion and explosion. So what causes the insufficient displacement of Copeland compressor? Let's take a look.

Control mode of servo motor

Torque control: the torque control mode is to set the external output torque of the motor shaft through the input of external analog quantity or the assignment of direct address. For example, if 10V corresponds to 5nm, when the external analog quantity is set to 5V, the output of the motor shaft is 2.5nm: if the load of the motor shaft is lower than 2.5nm, the motor will rotate forward, and when the external load is equal to 2.5nm
