Name [ID] Description Dim.
Max. current [494]
Motor current RMS value limitation on the converter output. During an excessive
converter load, maximal current can drop from the value Max. mot. current [5]
(page 71) to the value Permanent current [24] (page 47).
A
Current MT unfilt.
[49]
RMS value of the non filtered motor current (load). A
Curr. phase U
[1221]
U-phase current RMS value at the output of frequency converter. A
Curr. phase V [1222] V-phase current RMS value at the output of frequency converter. A
Curr. phase W
[1223]
W-phase current RMS value at the output of frequency converter. A
Sum of I-AC [831]
Filtrated absolute sum of AC currents for evaluation of leak or current
measurement fault.
A
UL1_rms [1519]
RMS value of L1 phase voltage. This voltage can represent supply or generated
grid voltage, according to connection.
V
UL2_rms [1520]
RMS value of L2 phase voltage. This voltage can represent supply or generated
grid voltage, according to connection.
V
UL3_rms [1521]
RMS value of L3 phase voltage. This voltage can represent supply or generated
grid voltage, according to connection.
V
4.2.3 Positioning
Group of parameters number [1146]
Quantities for position control diagnostics.

Name [ID] Description Dim.
Pos.
setpoint
[1149]
Position
[1147]
Position evaluated from Pos. feedback source [1141] (page 66) signal.
Pos. error
[1148]
Difference between position setpoint Pos. setpoint [1149] (page 17) and actual position
Position [1147] (page 17).
Absolute value of position error. The value is calculated after ramp and S-curve blocks,
so it can be lower than expected in transient state. It can be used as a signal for
switching the limit switches.
4.3 Inputs and outputs
Group of parameters number [859]
Diagnostics of the converter inputs and outputs.
4.3.1 BIN
Group of parameters number [1212]
MENU \ DIAGNOSTICS \ INPUTS AND OUTPUTS \ BIN
Name [ID] Description Dim.
Binary inputs [184] State of the binary inputs. Filled rectangle represents the BINx physical switch-on.
□ BIN1 State of 1st binary input (Terminal 1).
□ BIN2 State of 2nd binary input (Terminal 2).
□ BIN3 State of 3rd binary input (Terminal 3).
□ BIN4 State of 4th binary input (Terminal 4).
□ BIN5 State of 5th binary input (Terminal 5).
□ BIN6 State of 6th binary input (Terminal 6).
4.3.2 AIN
Group of parameters number [82]
Diagnostic group of quantities for the analog inputs of the converter AIN1 to AIN4.
