indicates one decimal place,
Motor feedback – current position. Unit is user unit, PUU.
Position command – current position. Unit is user unit,
PUU.
PT mode: it indicates the pulse command received by
the servo drive.
PR mode: it indicates the absolute position command.
It is equal to the pulse number sent by the host
(external) controller.
Position error counts between position command pulse
B
and feedback pulse. Unit is user unit, PUU.
Motor feedback – current position. Unit is encoder unit,
pulse.
Position command – current position. Unit is encoder
unit, pulse.
It is also the position command after electronic gear
ratio is set.
Position error counts between position command pulse
and feedback pulse. Unit is encoder unit, pulse.
Input frequency of pulse command received by the servo
drive.
B
Unit is Kpps. Applicable for PT and PR mode.
Actual motor speed. Unit is 0.1r/min.
The low-pass filter function is used so the value is more
stable.
Analog speed input command. Unit is 0.01Volt.
Integrated speed input command. Unit is 1r/min.
The command source may be from analog command /
B
internal parameter / position loop.
