System Variables List
The property code of each system variable is described as follows:
Monitoring variables are described in the following table according to the code
sequence:
Property Description
B BASE: Basic variables, can be selected via the UP / DOWN keys on the panel.
Dec, Hex
Display format on panel. Dec indicated Decimal, Hex indicates Hexadecimal.
Currently all the system variables are displayed in the Dec format.

(1)
000 (00h)
Feedback position
(PUU)
B, DEC Current feedback position of the motor encoder. PUU
001 (01h)
Position command
(PUU)
B, DEC
Current coordinate of the position command.
PT mode: Number of pulse commands received by the drive.
PR mode: Absolute coordinates of the position command.
PUU
002 (02h)
Position deviation
(PUU)
B, DEC Deviation between the position command and the feedback position. PUU
003 (03h)
Feedback position
(count)
B, DEC Current feedback position of the motor encoder. count
004 (04h)
Position command
(count)
B, DEC
Current coordinate of the Position command.
This is the command after the E-Gear ratio conversion.
count
005 (05h)
Position deviation
(count)
B, DEC Deviation between position command and feedback position. count
006 (06h)
Pulse command
frequency
B, DEC
Frequency of the pulse command received by the drive.
Applicable to PT, PR and I/O (Gear) modes
Kpps
007 (07h) Speed feedback B, DEC
Current motor speed. This is the speed after applying the low-pass filter, which makes it more
stable.
0.1 rpm
008 (08h)
Speed command
(analog)
B, DEC Speed command from the analog channel. 0.01 Volt
009 (09h)
Speed command
(integrated)
B, DEC Integrated Speed command. Source includes analog, register, or position loop. 0.1 rpm
010 (0Ah)
Torque command
(analog)
B, DEC Torque command from the analog channel. 0.01 Volt
011 (0Bh)
Torque command
(integrated)
B, DEC Integrated Torque command. Source includes analog, register, or speed loop. percentage (%)
012 (0Ch) Average load rate B, DEC Average load rate (moving average every 20 ms) from the servo drive. percentage (%)
013 (0Dh) Peak load rate B , DEC Maximum load rate from the drive. percentage (%)
014 (0Eh) DC Bus voltage B, DEC Rectified capacitor voltage. Volt
015 (0Fh) Load inertia ratio B, DEC Ratio of the load inertia to the motor inertia. 0.1 times
016 (10h) IGBT temperature B, DEC Temperature of IGBT. °C
017 (11h) Resonance frequency B, DEC
Resonance frequency of the system consists of two groups of frequencies: F1 and F2. The low word is
frequency F2, when the high word is frequency F1.
Hz
018 (12h) Z phase offset B, DEC
Offset value between motor position and Z phase; range: -4999…+5000 (-180 degrees to 180
degrees).
Where it overlaps with Z phase, the value is 0; the greater the value, the greater the offset.
180/5000 degree
