*1.
If you combine a
Σ
-7-Series SERVOPACK with a
Σ
-V-Series Option Module, the following
Σ
-V-Series SERVO-
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:
*3.
Always perform risk assessment for the system and confirm that the safety requirements are met.
*4.
The pressure feedback detection input applies to only FT40 specification SERVOPACKs.
