B0 : Position feedback (Position loop)
B1 : Motion command (Position loop)
B2 : Position Error (Position loop)
B3 : Velocity command (Position loop)
∗B4 : Σ Motion command (Position loop)
∗B5 : Σ Position feedback (Position loop)
B6 : Torque command (Velocity loop)
∗∗B8 : Σ Motor position feedback (Current loop)
(Note) You can trace the data marked “∗” only for high-speed axis or Learning axis.
You can trace the data marked “∗∗” only for high-speed axis.
(Note) You should set decimal notation converted from each trace data bit.
(Example) In case that you trace Σ Motion command (B4) and Σ Position feedback (B8) at same
time,
DTKND = 272 ← (100010000)
2
(Note) You can trace two or more data at once, but the order of trace data is not predetermined.
In only case of B4 and B5, the trace data are ΣMotion command and ΣPosition feedback in that order.
If possible, you should trace one kind of data.
(Note) You must trace B4 and B8 at the same time, and don’t trace together with the other data. This analysis
is often used at the piston lath in which the motor movement corresponding to work cross section is
drawn on Personal computer compared to user command.
In case of B4 and B8, the first data is ΣMotion command. The next N data are ΣMotor position feedback.
Till then this combination repeats.
N = (Velocity loop period) / (Current loop period)
(Note) If you don’t use this servo trace, you must set No.2025, No.2026, and No.2027 to 0.
7.1.2 Trace data unit
B0 : Position feedback Detective unit (Pulse / Position loop period)
B1 : Motion command Detective unit (Pulse / Position loop period)
B2 : Error Detective unit (Pulse)
B3 : Velocity command 0.915527/64 (min
-1
)
∗B4 : Σ Motion command Detective unit (Pulse)
∗B5 : Σ Position feedback Detective unit (Pulse)
B6 : Torque command Max. amplifier current / 7282 (Ap)
∗B8 : Σ Motor position feedback 1/2

(Note) These data reverse the sign beyond −32767 to +32767 because these data are 16 bits.
For analysis, you need to connect the data consistently taking the overflow in consideration.
(Note) Caution the value with the summation (B4, B5, and B8).
These data are always accumulated from Power supply ON.
These summation is 0 cleared only when trace cancel is canceled in servo trace screen.
(Refer to 7.1.3 Operation of servo trace.)
(Note) Take care of full-closed system in which data unit of B7, B8 is detective unit (Pulse).
