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.
Name
Description
Cumulative feedback pulses
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.
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 value is negative under the reverse command.
Command pulse frequency
The frequency of the position command input pulses is displayed.
Command pulse frequency
The command pulse frequency is converted and displayed in the servo
(speed unit)
motor speed unit.
Analog speed command
In the speed control mode, the analog speed command voltage is
voltage/Analog speed limit
displayed; in the torque control mode, the analog speed limit voltage is
voltage
displayed.
Analog torque command
In the position/speed control mode, the analog torque limit voltage is
voltage/Analog torque limit
displayed; in the torque control mode, the analog speed command voltage
voltage
is displayed.
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 value 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-
The position within one revolution is displayed in the encoder pulse unit.
revolution
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.
Load to motor inertia ratio
The estimated ratio of the load inertia moment to the servo motor inertia
moment is displayed.
Bus voltage
The bus voltage of the converter part of the servo amplifier (between P+
and N-) is displayed.
Load-side encoder
The feedback pulses from the load-side encoder are counted and
cumulative feedback pulses
displayed.
*2
Load-side encoder droop
Droop pulses of the deviation counter between a load-side position and a
*2
pulses
command are displayed.
