*1.
PACKs specifications must be used: a surrounding air temperature of 0°C to 55°C and an altitude of 1,000 m
max. Also, the applicable surrounding range cannot be increased by derating.
*2.
The coefficient of speed fluctuation for load fluctuation is defined as follows:
Coefficient of speed fluctuation = No-load motor speed - Total-load motor speed
*3.
Always perform risk assessment for the system and confirm that the safety requirements are met.
