[1617] Speed [RPM] Motor speed reference. Actual speed will depend on slip compensation being used (compensation
set in par. 1-62
Slip Compensation
). If not used, actual speed will be the value read in the display
minus motor slip.
[1618] Motor Thermal Thermal load on the motor, calculated by the ETR function. See also parameter group 1-9* Motor
Temperature.
[1622] Torque [%] Shows the actual torque produced, in percentage.
[1626] Power Filtered [kW]
[1627] Power Filtered [hp]
[1630] DC Link Voltage Intermediate circuit voltage in the adjustable frequency drive.
[1632] Brake Energy /s Present braking energy transferred to an external brake resistor.
Stated as an instantaneous value.
[1633] Brake Energy /2 min Braking energy transferred to an external brake resistor. The mean power is calculated continuously
for the most recent 120 seconds.
[1634] Heatsink Temp. Present heatsink temperature of the adjustable frequency drive. The cut-out limit is 203° ± 9°F [95°
± 5°C]; cutting back in occurs at 158° ± 9°F [70° ± 5°C].
[1635] Inverter Thermal Percentage load of the inverters
[1636] Inv. Nom. Current Nominal current of the adjustable frequency drive.
[1637] Inv. Max. Current Maximum current of the adjustable frequency drive.
[1638] SL Controller State State of the event executed by the control
[1639] Control Card Temp. Temperature of the control card.
[1650] External Reference Sum of the external reference as a percentage, i.e., the sum of analog/pulse/bus.
[1652] Feedback [Unit] Reference value from programmed digital input(s).
[1653] Digi Pot Reference View the contribution of the digital potentiometer to the actual reference Feedback.
[1654] Feedback 1 [Unit] View the value of Feedback 1. See also par. 20-0*.
[1655] Feedback 2 [Unit] View the value of Feedback 2. See also par. 20-0*.
[1656] Feedback 3 [Unit] View the value of Feedback 3. See also par. 20-0*.
[1658] PID Output [%] Returns the Drive Closed-loop PID controller output value in percent.
[1660] Digital Input Displays the status of the digital inputs. Signal low = 0; Signal high = 1.
Regarding order, see par. 16-60
Digital Input
. Bit 0 is at the extreme right.
[1661] Terminal 53 Switch Setting Setting of input terminal 53. Current = 0; Voltage = 1.
[1662] Analog Input 53 Actual value at input 53 either as a reference or protection value.
[1663] Terminal 54 Switch Setting Setting of input terminal 54. Current = 0; Voltage = 1.
[1664] Analog Input 54 Actual value at input 54 either as reference or protection value.
[1665] Analog Output 42 [mA] Actual value at output 42 in mA. Use par. 6-50
Terminal 42 Output
to select the variable to be
represented by output 42.
[1666] Digital Output [bin] Binary value of all digital outputs.
[1667] Pulse Input #29 [Hz] Actual value of the frequency applied at terminal 29 as a pulse input.
[1668] Pulse Input #33 [Hz] Actual value of the frequency applied at terminal 33 as a pulse input.
