Description
1.1
>MEASURE
-
This section displays all size units measured by the
driver; moreover it stores the minimum or maximum
values measured for some size units.
1.1.1
VBUS RMS [V]
-
3-phase root mean square voltage at the driver
infeed. This value depends on the voltage at the
ends of the main filter capacitors. As a consequence,
the DC bus voltage variations also affect this value.
. 1.1.2
VBUS DC [V]
-
Driver mains voltage, obtained by adjusting and
filtering the input 3-phase voltage. This value
depends on the motor load variations.
1.1.3
VBUS DC MIN [V]
-
Minimum DC bus voltage. This datum allows
monitoring the motor load peaks, due to
accelerations, inertial mass increase or mains
voltage fluctuations. If this value is below the safety
limit, the driver will signal error
14
.
1.1.4
VBUS DC MAX [V]
-
Maximum DC bus voltage. Thanks to this datum,
you can infer the limit reached by the DC bus
voltage due to the motor decelerations, inertial mass
decrease or mains voltage fluctuations. If this value
exceeds the safety limit, the driver will signal error
10
.
1.1.5
IQ RMS [A]
-
Calculation of the rms direct current, by measuring
the motor phase currents. This is the index of
absorption required by the motor.
1.1.6
IQ MAX [A]
-
Direct current maximum value.
1.1.7
ID RMS [A]
-
Calculation of the rms reverse current, by measuring
the motor phase currents.
1.1.8
ID MAX [A]
-
Reverse current maximum value.
1.1.9
SPEED [rpm]
-
Motor rotation speed.
1.1.10
SPEED REF [rpm]
-
Speed value, set by the active controller, that the
motor will try to reach. If this value exceeds the limit
prescribed by the driver manufacturer, the error
16
will be displayed.
1.1.11
TORQUE [Nm]
-
Torque generated by the motor.
1.1.12
TORQUE MAX [Nm]
-
Maximum torque generated by the motor.
1.1.13
DRIVE TEMP
[°C]
-
Driver dissipator temperature.
1.1.14
DRIVE TEMP MAX
[°C]
-
Driver dissipator max temperature. If this value
exceeds the limit prescribed by the driver
manufacturer, the error
7
will be displayed.
1.1.15
MOTOR TEMP
[°C]
-
Motor temperature.
1.1.16
MOTOR TEMP MAX
[°C]
-
Motor max temperature. If the limit set in the
parameter
TEMP MAX is exceeded, error
6
will be
displayed.
1.1.17
BRAKE TEMP
[°C]
-
Dynamic brake resistor temperature.
1.1.18
BRAKE TEMP MAX
[°C]
-
Dynamic brake resistor max temperature. If this
value exceeds the temperature limit, error
13
will be
displayed.
