6.11.5.3 Controlled variable input
(1) Speed settings
When using DI input to set the speed, set function code F01 or C25 (whichever is to be enabled)
according to the switch state (DIA or DIB). For example, to enable F01 on a card set to DIA, set F01 to 6.
Control inputs [N2/N1] are used to switch between F01 and C25.

BCD input is used in applications where the motor speed is converted to the machine speed. For example,
when a motor operating at 1,500 r/min. is connected to a machinery shaft via a 5:1 gear, the machinery
shaft will rotate at 300.0 r/min. DI input of 3,000 while using a BCD setting (o03 or o04) of 3,000 with
these function codes would result in rotation of 300.0 r/min. (1,500 r/min. for the motor).

at 300.0 r/min.)

(2) Torque, torque current, and torque limit input
When assigning DI input to torque (torque commands, torque current commands, and torque limits), it is
necessary to define DIA and DIB use with the function codes H41, H42, F42, and F43 according to the
function being used. For more information, see the corresponding sections of Chapter 4.
