1) The task ID to change a value can be derived from the data width (2 or 4) specified in the format.
Examples: I2 ––> AK = 2 for array parameters AK = 7, C4 ––> AK = 3 for array parameters AK = 8
2) Formats: ––> refer to Chapter 4.3, Table 4-16
3) Traversing blocks 1 and 2: Speed = P82:x P26 P24 P8
Traversing blocks 3 to 27: Closed–loop speed contr. operation: Speed = P82:x P24 P8
Closed–loop pos. contr. operation: Velocity = P82:x P24 P10
4) Traversing blocks 1 and 2: Acceleration = P83:x P27 P25 P9
Traversing blocks 3 to 27: Closed–loop speed contr. operation: Acceleration = P83:x P25 P9
Closed–loop position contr. operation: Accel. = P83:x P25 P22
5) Negative value: ––> Direction of rotation reversal of the motor
