Variable name /
property
Feedback position Current feedback position of the motor encoder.
(PUU) B Unit: Pulse of User Unit (PUU).
Current coordinate of the Position command. Unit: Pulse of
User Unit (PUU).
Position command
PT mode: number of pulse commands received by the servo
(PUU) B
drive.
PR mode: absolute coordinates of the Position command.
Position deviation Deviation between the Position command and the feedback
(PUU) B position. Unit: Pulse of User Unit (PUU).
Feedback position Current feedback position of the motor encoder.
(pulse) B Unit: encoder unit (pulse).
Current coordinate of the Position command. Unit: encoder unit
Position command
(pulse).
(pulse) B
This is the command after the E-Gear ratio conversion.
Position deviation Deviation between the Position command and the feedback
(pulse) B position. Unit: encoder unit (pulse).
Pulse command Frequency of the pulse command received by the drive.
frequency B Unit: Kpps. Applicable to PT / PR modes.
Current motor speed. Unit: 0.1 rpm.
Speed feedback
This is the speed after applying the low-pass filter, which makes
B D1 Dec
it more stable.
Speed command
(analog)
Speed command from the analog channel. Unit: 0.01 Volt.
B D2 Dec
Integrated Speed command. Unit: 0.1 rpm.
Speed command
(integrated) B
Source includes analog, register, or position loop.
Torque command
(analog)
Torque command from the analog channel. Unit: 0.01 Volt.
B D2 Dec
Integrated Torque command. Unit: percentage (%).
Torque command
(integrated) B
Source includes analog, register, or speed loop.
Average load rate (moving average every 20 ms) from the
Average load rate B
servo drive. Unit: percentage (%).
Peak load rate B Maximum load rate from the drive. Unit: percentage (%).
DC Bus voltage B Rectified capacitor voltage. Unit: Volt.
Load inertia ratio
Ratio of the load inertia to the motor inertia. Unit: 0.1 times.
B D1 Dec
IGBT temperature B Temperature of IGBT. Unit: °C.
Resonance frequency of the system consists of two groups of
frequencies: F1 and F2
When monitoring from the panel, press the SHF key to switch
between F1 and F2:
Resonance frequency
F2 displays zero decimal places; F1 displays 1 decimal place.
B Dec
When reading by communication (mapping parameter):
Low word returns frequency F2.
High word returns frequency F1.
Offset value between motor position and Z phase;
Z phase offset range: -4999 to +5000.
B Dec Where it overlaps with Z phase, the value is 0; the greater the
value, the greater the offset.
