krak,
You didn't mention the amp draw of the motor. But I'll take a stab at it any way.
Dart makes a controller for motors up to 10 amps #65E10 you will need a 10 volt isolated analog output from the PLC. This presuming you have 24v DC power supply to work with.
Then if your motor is less than three amps perhaps this little cutie will work for you. It's designed for driving direct drive analog DC coils up to 3 amps. but should work on a motor also. And a isolated 10 volt analog output is not needed. http://www.pwmcontrols.com/

Use a DRV102 PWM Driver. It's a piece of cake to use and only costs $7.00. I use it to control a +12VDC motor..

I tend to favor the drive method myself (such as the DART unit already mentioned). Unless you really like playing with integrated circuits or the cost has to be kept at an absolute minimum, you 're better off w/ a complete drive. K-B Electronics also makes some decent drives.
A quick call to either Mfg. can solve your problem.
