5 MONITORING
5.1 Explanation of monitor signals
Monitor signal (analog) and analog monitor [G]
On MR Configurator2, the status of the monitor signal (analog) can be obtained by using the "Display All" function and the
graph function.
Refer to the list in this section for the signals which can be obtained with the "Display All" function and the graph function.
Signals that can be set with the analog monitor are also shown in the lists.

Cumulative feedback pulses The feedback pulses from the servo motor encoder are counted and
displayed.
The displayed value is limited within the range of "-999999999 to
999999999". When the value exceeds the upper or lower limit, it changes
to "0".
The value is negative in reverse rotation.
In the fully closed loop control mode, the value is in load-side encoder
units with the gear taken into consideration.
The fully closed loop control mode can be used for servo amplifiers with
firmware version A5 or later.
Servo motor speed The servo motor speed is displayed.
Droop pulses The number of droop pulses in the deviation counter is displayed. The
value is negative in reverse rotation. The number of pulses is displayed in
the units of encoder pulses.
Cumulative command pulses Position command input pulses are counted and displayed.
The displayed value is limited within the range of "-999999999 to
999999999". When the value exceeds the upper or lower limit, it changes
to "0".
The value is negative under the reverse command.
When other than "3" (pulse) is set in [Pr. PT01.2 Unit for position data], "0"
is displayed.
Command pulse frequency The frequency of the position command input pulses is displayed.
When other than "3" (pulse) is set in [Pr. PT01.2 Unit for position data], "0"
is displayed.
Command pulse frequency
(speed unit)
The command pulse frequency is converted and displayed in the servo
motor speed unit.
Regenerative load ratio The ratio of regenerative power to permissible regenerative power is
displayed as a percentage.
Effective load ratio The continuous effective load current is displayed. The effective load ratio
in relation to the rated current (= 100 %) is displayed.
Peak load ratio The rated torque is displayed as 100 %. The maximum value of the torque
generated in the past 15 seconds is displayed.
Torque/instantaneous torque The instantaneous torque is displayed.
The rated torque is displayed as 100 %. The value of the generated torque
is displayed in real time.
Position within one-
revolution
The position within one-revolution is displayed in the encoder pulse unit.
In the fully closed loop control mode, the position within one-revolution is
displayed in the servo motor encoder unit.
The fully closed loop control mode can be used for servo amplifiers with
firmware version A5 or later.
For the linear servo motor control mode, the value of manufacturer setting
is displayed.
ABS counter The travel distance from the home position is displayed as a multi-
revolution counter value of the absolution position encoder in the
absolution position detection system.
For the fully closed loop control mode, the ABS counter is displayed in the
servo motor encoder unit.
The fully closed loop control mode can be used for servo amplifiers with
firmware version A5 or later.
For the linear servo motor control mode, the value of manufacturer setting
is displayed.

following manuals.
