4-57 Warning Feedback HighRange: Function:999999.999ReferenceFeed-backUnit*[ par. 4-56 -999999.999ReferenceFeed-backUnit]Enter the upper feedbacklimit. When the feedbackexceeds this limit, thedisplay reads Feedb High.The signal outputs canbe programmed toproduce a status signalon terminal 27 or 29 (FC302 only) and on relayoutput 01 or 02 (FC 302only).4-58 Missing Motor Phase FunctionOption: Function:NOTICEThis parameter cannot be adjustedwhile the motor is running.Displays alarm 30, 31 or 32 in the event of amissing motor phase. It is stronglyrecommended to enable to avoid motordamage.[0] Disabled The frequency converter does not issue amissing motor phase alarm. Not recommendeddue to risk of motor damage.[1] Trip 100 ms For a quick detection time and alarm in theevent of a missing motor phase.[2] Trip 1000msFor a slow detection time and alarm in theevent of a missing motor phase.[3] Trip 100ms3ph detec.[5] MotorCheckThe frequency converter detects automaticallywhen the motor is disconnected and resumesoperation once the motor is connected again.3.6.4 4-6* Speed BypassSome systems call for avoiding certain output frequenciesor speeds, due to resonance problems in the system. Amaximum of 4 frequency or speed ranges can be avoided.4-60 Bypass Speed From [RPM]Array [4]Range: Function:Size related* [ 0 - par.4-13 RPM]Some systems call for avoiding certainoutput speeds due to resonanceproblems in the system. Enter thelower limits of the speeds to beavoided.4-61 Bypass Speed From [Hz]Array [4]Range: Function:Size related* [ 0 - par.4-14 Hz]Some systems call for avoiding certainoutput speeds due to resonanceproblems in the system. Enter thelower limits of the speeds to beavoided.4-62 Bypass Speed To [RPM]Array [4]Range: Function:Size related* [ 0 - par.4-13 RPM]Some systems call for avoiding certainoutput speeds due to resonanceproblems in the system. Enter theupper limits of the speeds to beavoided.4-63 Bypass Speed To [Hz]Array [4]Range: Function:Size related* [ 0 - par.4-14 Hz]Some systems call for avoiding certainoutput speeds due to resonanceproblems in the system. Enter theupper limits of the speeds to beavoided.3.7 Parameters: 5-** Digital In/Out3.7.1 5-0* Digital I/O ModeParameters for configuring the input and output usingNPN and PNP.5-00 Digital I/O ModeOption: Function:Digital inputs and programmed digital outputs arepre-programmable for operation either in PNP or NPNsystems.[0] * PNP Action on positive directional pulses (↕). PNP systemsare pulled down to GND.[1] NPN Action on negative directional pulses (↕). NPNsystems are pulled up to + 24 V, internally in thefrequency converter.NOTICEOnce this parameter has been changed, it must beactivated by performing a power cycle.Parameter Descriptions VLT® AutomationDrive FC 301/302 Programming Guide74 MG33MH02 - Rev. 2013-09-3033
