5.1 Explanation of monitor signals
Description
The frequency at the time of oscillation detection is displayed.
The number of times the tough drive function has activated is displayed.
For the MR-J5_-G_ or the MR-J5W_-_G_, the unit power consumption is
displayed. A positive value is displayed during power running, and a
negative value is displayed during regeneration.
For the MR-J5D_-_G_, the power consumption of the converter unit
connected with the protection coordination cable is displayed.
When multiple MR-J5D_-_G_ are connected to the converter unit, "0" is
displayed for the second and subsequent MR-J5D_-_G_.
For the MR-J5_-G_ and the MR-J5W_-_G_, the unit total power
consumption is displayed.
For the MR-J5D_-_G_, the total power consumption of the converter unit
connected with the protection coordination cable is displayed.
When multiple MR-J5D_-_G_ are connected to the converter unit, "0" is
displayed for the second and subsequent MR-J5D_-_G_.
The margin for the excessive error alarm trigger level is displayed in the
encoder pulse unit. The excessive error alarm is triggered when the
margin is 0 pulse.
The margins for the alarm levels of [AL. 050 Overload 1] and [AL. 051
Overload 2] are displayed as a percentage.
The overshoot amount during position mode and positioning mode is
displayed in units of encoder pulses.
The difference between the necessary torque and the actually required
torque (torque current value) to drive the servo motor is displayed as the
torque equivalent to disturbance.
In the profile position mode (pp) and point table mode (pt), the current
position of the command unit with the machine home position set as "0" is
displayed. In other control modes, the current position of the command
unit is displayed.
In the profile position mode (pp) and point table mode (pt), the command
current position with the machine home position set as "0" is displayed.
This indicates the position command from the controller in the cyclic
synchronous position mode (csp).
In the profile position mode (pp) and point table mode (pt), the selected
profile position or the remaining distance to the command position of the
point table is displayed. In other control modes, "0" is displayed.
In the positioning mode (point table method), the selected point table
number is displayed. In other control modes, "0" is displayed.
The selected number is displayed during a temporary stop or in JOG
operation mode.
This indicates the current command applied to the servo motor.
This indicates the speed command being applied to the servo motor.
In the position mode and positioning mode, the speed command
calculated from the position command and command filter is displayed.
The command speed to be used for position control is displayed as the
command output of the analog monitor.
The command speed to be used for speed control is displayed as the
command output of the analog monitor.
The torque command in the torque mode or the target torque value in the
continuous operation to torque control mode is displayed. "0" is displayed
in the position mode, positioning mode, and velocity mode.
The speed limit value in the torque mode or continuous operation to
torque control mode is displayed.
"0" is displayed in the position mode, positioning mode, and velocity
mode.
*1
This indicates the U-phase current value applied to the servo motor in
internal units.
*1
This indicates the V-phase current value applied to the servo motor in
internal units.
