*1.
These values are for operation in combination with a SERVOPACK when the temperature of the armature winding is 100
°
C. The values
for other items are at 20
°
C. These are typical values.
*2.
The rated forces are the continuous allowable force values at a surrounding air temperature of 40
°
C with an aluminum heat sink of the
dimensions given in the following table.
