9.6.2.12 Setting Max. Speed ON / OFF function |11D|The value for “Max Speed” adjusted in menu “Settings”, is activated over a digital input. I.e. the unitworks independently of the controller function firm with this value.Contact at digital input e.g. “Digital In 1”.This function influences both circuits in operation with two control circuits.15.05.2009v_11d_max_drehzahl_m.vsdControllerD1 D1= 80 %10- - - - -10 = 0 .. 100 %1M1 Setting “Max.

The height of the “brake level” is set in “Motor Setup”.The setting “DC brake level” refers in % to the value set in “MotorRated Curr.”.Setting range: 1 - 100 %Factory setting: 50 %A current is impressed here, which does not permit any rotation of the fans. The value required toprevent any freezing depends on the ambient conditions and the connected motor’s technical data.The setting effected is to be checked under real conditions. The higher the setting, the greater theheating output generated in the motor (heat dissipation). The motor heating or stationary heating canonly become active, where there is no given modulation as a result of regulation.To prevent any overheating, motor protection in the form of thermal protection installed in the motor isrequired ( motor protection). The heating function is switched off when the motor protection functionof the regulating unit responds.InfoThe active motor heating is displayed by the radiator symbol.28.7 °CE1 ActualOperating Instructions Fcontrol – model series FKDM25/32AM-C ProgrammingL-BAL-E214-GB 1446 Index 002 Part.-No.54/99
