iMac Shuts Down Instead of Staying in Sleep Mode

My iMac running High Sierra will shut down instead of going into sleep mode causing me to have to hit the power button after the computer has not been used for an hour.

Is there a setting causing this, or a problem that needs to be resolved.

Thanks in advance.

MacBook, OS X El Capitan (10.11.5)
