Figure 6.14.1.1: Motor potentiometer

Motor pot sign -

Only for 6KDV3 ... Q4...! Selection of the “Counterclockwise” rotation when the

changeover is carried out via the terminal strip. The Motor pot sign - parameter is

linked with the Motor pot sign + parameter via an XOR function. This means that the

command (+24V) must be given only to one of the two terminals.

High ”Counter-clockwise” rotation direction selected.

Low ”Counter-clockwise” rotation direction not selected.

Motor pot reset.

When the Reset command is activated and the drive is switched off, the restart begins

at “Zero” speed. The command is only possible with the drive switched off!

Motor pot up

The drive is accelerated with the preselected ramp. The setting is either carried out via

the terminal, serial interface or Bus.

Motor pot down

The drive is decelerated with the preselected ramp. The setting is either carried out via

the terminal, serial interface or Bus.

When the motor potentiometer function is active (Enable motor pot), the current speed reference value is

shown in the Motor pot submenu of the keypad. When controlled via the keypad, the drive can be accelerated

by pressing the “+” key and decelerated by pressing the “-” key. This corresponds to the commands Motor pot

up and. Motor pot down. Select the menu point Motor pot oper for this purpose.
The speed of the drive can be adjusted between 0 to 100 % by setting the command Motor pot up. The drive

reduces the speed between 100 and 0 % by setting the command Motor pot down.If the command is given when

the drive is already at a stop, it will not cause the reverse running of the drive.
