NSK EDD Megatorque Motor - Positioning Operation Modes

8. More Advanced Function
— 8-31 —
8.6. Positioning Operation
8.6.1. Acceleration Profiling and Individual Acceleration Setting
 The Driver Unit Model EDD has the function for acceleration profiling and individual setting of
acceleration and deceleration.
 These functions are available for the positioning operation, jogging operation and Home Return
operation.
 Utilize these functions according to operation velocity and load conditions.

 The parameters CSA (Acceleration pattern select) and CSB (Deceleration pattern select) set the
acceleration profiling. Table 8-33 in the next page describes the availability of acceleration profiling.
 When setting CSB0 to the parameter CSB, the deceleration profiling will be the same as that of acceleration.
 Acceleration and deceleration specified by the parameters MA and MB denote average acceleration and
deceleration respectively.
