Note
1 The above diagrams represent deceleration under maximum torque. Applying an accel-
eration/deceleration curve to the reference allows operation outside the range of the dia-
grams. (That is, characteristics change according to pattern of operation and load )condi-
tions.
2 As for 400W and 750W types, make sure not to perform frequent accel/decel, since re-
generativeresistor is incorporated inside the Servopack.
