backlash on reversal
Explanation:
Siemens, Energie- und Automatisierungstechnik, lists:

Umkehrspiel n
backlash on reversal

A search on that term yielded a number of pertinent hits, see if this is what you need within your context:
Despite extensive fine tuning, ball screw spindle drives cannot exceed 6m in length and a velocity of 1m/s. Non linear influences in the control system, such as mechanical play, backlash on reversal and inertia, affect accuracy and machining speed. A machine tool that is supposed to operate outside these limits must be free of such influences. As the mechanical transmission elements have the sole function of converting a rotary movement into a linear one, the future points towards linear direct drives. Direct drives require no conversion and can be installed wherever the power is required.

Each test is automatic once the number of stops is entered into the PC. However, Sniegowski runs multiple tests in both directions, to allow him to check the drive's repeatability, as well as the effect of backlash during reversal. In a typical inspection, he hits every stop six times: three revolutions clockwise, three counterclockwise. Including setup and dismantling time along with these six test runs, the entire inspection process takes him from about an hour for a two-stop drive, up to three hours for a complex drive with 30-40 stops.

NOTE: All Float-A-Shaft units have 3° to 5° of backlash on reversal of input.

Experimental and clinical experience have shown that the catheter to probe friction is far less with the Luxtron fibre optic temperature probes than with the BSD Bowman thermistor temperature probes. The Luxtron probe also is stiffer, resisting compressive forces on insertion better than the Bsn Bowman thermistor, thus reducing mechanical backlash. When the friction between the probe and catheter is low, the backlash on reversal of travel is far less than the 0.75 mm step resolution of the mapping device.
