Why does starting a cryopump cause the PLC main unit to shut down?

The motor bearings of the pump froze due to the cold weather; why does starting it cause the PLC’s CPU to stop working?

It shouldn’t make much of a difference, right? Is the power supply for the PLC and the motor coming from the same circuit? When the motor stalls, the voltage drops, which causes the PLC to lose power.
