bMctrlI2xtOverload
BOOL
Status of the Motor load monitoring (I2xt)
TRUE Thermal motor overload (I
2
xt) ≥ motor overload setting (C00120)
• Lenze setting: C00120
= 100 %.
nMctrlI2xtRate_a
INT
Current thermal motor load (I2xt)
• Scaling: 16384 ≡ 100 %
bMctrlMotorPTC
BOOL
Status of the Motor temperature monitoring (PTC)
TRUE Temperature monitoring: An error has been detected
bMctrlMotorTemp
BOOL
TRUE Thermal motor overload
bMctrlHeatSinkTemp
BOOL
TRUE Thermal inverter overload
• The heatsink temperature (display in C00061
) has reached the
maximally permissible temperature. The "oH1: Overtemperature
heatsink" error message is pending and the "Fault" response is
activated.
• Furthermore, this output is set if the heatsink temperature has
exceeded the maximally permissible temperature for the
switching frequency set. A response with an "oH4: Heatsink
temp.. > switch-off temp. -5°C" error message can be set in
C00582
. In the Lenze setting, no response will be effected.
bMctrlMainsFault
BOOL
Status of the Mains phase failure monitoring
TRUE Mains phase failure/Mains failure
bMctrlFanFault
BOOL
TRUE Fan monitoring: An error has been detected
bMctrlNmaxForFChop
BOOL
TRUE The maximum field frequency for the respective switching
frequency has been exceeded.
bMctrlShortCircuit
BOOL
TRUE Motor short circuit has been detected
bMctrlEarthFault
BOOL
TRUE Earth fault has been detected
bMctrlUVDetected
BOOL
TRUE An undervoltage has been detected
bMctrlOVDetected
BOOL
TRUE An overvoltage has been detected
bMctrlBrakeChopperFault
BOOL
Status of the Brake resistor monitoring (I2xt)
• This output is set independent of the set error response of the monitoring
function.
TRUE The I
2
xt utilisation has reached the switch-off threshold set in
C00572
.
• Lenze setting: C00572
= 100 %.
wUB24V
WORD
Current 24 V supply voltage
• Scaling: 1000 ≡ 1.000 V
nMctrlActiveOutputPower_a
INT
(from version 14.00.00)
Current active output power
• Scaling: 16384 ≡ double rated power of the inverter
nMctrl
ApparentOutputPower_a
INT
(from version 14.00.00)
Current apparent output power
• Scaling: 16384 ≡ double rated power of the inverter
nMctrlCosinePhiAct_a
INT
(from version 14.00.00)
Current cosine phi
• Scaling: 16384 ≡ cosine phi of 1.0
