Monitor signal (analog) and analog monitor [A]
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.

5.1 Explanation of monitor signals
Description
The feedback pulses from the servo motor encoder are counted and
displayed.
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.
The servo motor speed is displayed.
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.
Position command input pulses are counted and displayed.
The value is negative under the reverse command.
The frequency of the position command input pulses is displayed.
The command pulse frequency is converted and displayed in the servo
motor speed unit.
In the speed control mode, the analog speed command voltage is
displayed; in the torque control mode, the analog speed limit voltage is
displayed.
In the position/speed control mode, the analog torque limit voltage is
displayed; in the torque control mode, the analog speed command voltage
is displayed.
The ratio of regenerative power to permissible regenerative power is
displayed as a percentage.
The continuous effective load current is displayed. The effective value in
relation to the rated current (= 100 %) is displayed.
The rated torque is displayed as 100 %. The maximum value of the torque
generated in the past 15 seconds is displayed.
The instantaneous torque is displayed.
The rated torque is displayed as 100 %. The value of the generated torque
is displayed in real time.
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.
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.
The estimated ratio of the load inertia moment to the servo motor inertia
moment is displayed.
The bus voltage of the converter part of the servo amplifier (between P+
and N-) is displayed.
The feedback pulses from the load-side encoder are counted and
displayed.
Droop pulses of the deviation counter between a load-side position and a
command are displayed.
