Special functions

Motorpoti inc / dec time (oP.59)

This parameter denes the time for the motorpoti in order to run from 0...100%. The time is adjustable between

0...50000 s.

Control range (oP.53, oP.54)

The control range is limited by parameters oP.53 "motorpoti min. value" and oP.54 "motorpoti max. value" (see

picture 7.15.3).

Display of motor potentiometer value (ru.37)

This parameter shows the current value of the motor potentiometer in percent.

Motor potentiometer value (oP.52)

A percentage value can be adjusted directly by operator or bus via this parameter. The ramp time remains

unconsidered at this setting.

The parameter value is limited by oP.53 / oP.54. If a digital input is set for increasing or decreasing the motorpoti

value, the value of oP.52 changes.

7.15.4 Timer / counter programming

Two timers are incorporated in the COMBIVERT. As long as one of the adjustable starting conditions (LE.18/23)

or a programmable input (LE.17/22) is set, the timer counts until reaching the nal value range. If one of the re-

set conditions (LE.20/25) is fullled or one programmable input (LE.19/24) is set, the timer jumps back to zero.

The clock source and the counting direction is adjusted with LE.21/26. It can be counted in seconds, hours or

by a special programmed input for that. The current timer content is displayed in ru.43/44. Switching condition

37/38 is set with reaching an adjustable switching level (LE.00...07). It can be used to set an output.
