Bus Voltage		Up to 320 VDC
Continuous Current, Stall	A_pk	2	3.7	3.8	3.4	3.1
	A_rms	1.43	2.6	2.7	2.4	2.2
Finish	Table	Hardcoat
	Stage	Black Anodized

Note:
1. Collet chuck accepts Rego-Fix ER collets manufactured to DIN6499 specifications only.
2. Measured TIR of precision gage pin chucked with an ultraprecision ER collet (DIN6499) 6 mm away from collet face with no load.
3. Maximum loads are mutually exclusive. Loading limits are due to the collet chuck mechanism. Contact Aerotech directly if part load requirement exceeds specifications.
4. Maximum speed based on stage capability; maximum application velocity may be limited by system data rate, system resolution, and load.
5. Collet chuck mechanism is normally-closed. Collet mechanism requires air to open collet chuck. Air supply must be dry (0º F dew point) oil-less air OR 99.99% pure nitrogen. Air or nitrogen must be filtered to 0.25 micron particle size or better. With 3-jaw gripper, air or nitrogen should be filtered to 20 micron particle size or better.
