*1.
These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing 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 alu-
minum heat sink of the dimensions given in the following table.

To externally connect dynamic brake resistor, select hardware option specification 020 for the SERVOPACK.
However, you cannot externally connect dynamic brake resistor if you use the following SERVOPACKs (maxi-
mum applicable motor capacity: 400 W).
