2 types of operation are available

1 Use of single action buttons : two logic inputs are required in addition to the operating direction(s). The input 

assigned to the “+ speed” command increases the speed, the input assigned to the “- speed” command 
decreases the speed.

This function accesses the Str save reference parameter in the Control menu.

2 Use of double action buttons : only one logic input assigned to + speed is required.

+ / - speed with double action buttons :

Wiring example :

LI1 : forward
LIx : reverse
LIy : + speed

This type of +/- speed is incompatible with 3-wire control. In this case, the - speed function is automatically
assigned to the logic input with the highest index (for example : LI3 (+ speed), LI4 (- speed)).

Description : 1 button pressed twice for each direction of rotation.

Each action closes a volt-free contact.
