Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. 
Actual drive case temperature, measured on baseplate, should not exceed

 

90°C (194°F) within the operating 

ambient conditions.  

 

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive 
mounting screws. Shock may be applied in the X, Y or Z axis.

These drives comply with the performance levels specified in this document when subjected to a maximum 
operating shock of 300 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more 
than two times per second. For 11 msec shock duration, these drives will withstand operating shock up to 150 
Gs.
